Phil Mickelson remained on track to become golf's oldest major winner as he held a two-shot lead at the halfway stage of his final round at the US PGA Championship.  

The 50-year-old had ended Saturday's action at Kiawah Island with a one-stroke advantage over Brooks Koepka, who is seeking to win the tournament for a third time in four years.  

Mickelson's slender advantage disappeared with a three-putt bogey at the opening hole, setting the tone for an uneven front nine that saw him record just three pars but still reach seven under.  

The undoubted highlight was a wonderful chip from a tricky greenside bunker by the fifth green that found the cup, delighting a crowd that sensed they could be witnessing history in the making. 

Playing partner Koepka also had his struggles, following up an opening birdie with a double-bogey seven at the second. He sat at five under through nine, the same score as Louis Oosthuizen. 

Abraham Ancer had shown how it was possible to go low on Sunday, carding the best round of the week with a blemish-free 65 that owed much to a fast start.  

The Mexican birdied four of his opening six holes before picking up a further shot prior to the turn, seeing him go out in 31 strokes. While he cooled off on the way back in, it was still an impressive display.  

While his charge came too late to mount a challenge for the tournament, Ancer feels his superb score is a further sign of how he is getting close to making a major breakthrough in his career.  

"I usually like golf courses that are going to be tough, it's not just going to be a birdie-fest and you have to grind it out and have to hit the ball well where you are supposed to," he told Sky Sports.  

"It's not that I don't care about other events, I try to think about every event the same and try to win every time, but I do feel my game is better for golf courses that are tougher." 

Justin Burrowes extended his lead to 11 strokes on day three of the Alliance National Amateur Golf Championship on Saturday at the Caymanas Golf Club. He shot two under par 70 for a three-day total of 212 (73, 69, 70) and is poised to secure victory when play resumes at 7:30 today.

“Today (Saturday) was another pretty good day. (I) gave myself a lot of opportunities, which is really what I set out to do.  It didn't convert as much as I would have liked but still, all in all, I would say a lot more positives than negatives today,” said Burrowes, who started the day with a birdie and followed up with three more on holes 11, 12 and 15 while posting two bogeys on holes 14 and 18.

“In a good place to build on.  The course was definitely more inviting today with the softer conditions - no wind and no rain.  It was definitely more inviting. I played solid but I didn't hold enough putts today to go really deep so hopefully, I can build on today and do that tomorrow (Sunday)."

Meanwhile, defending champion William Knibbs posted his first under-par score of 70 but is still 11 strokes off the lead.  He has a combined score of 223 after posting 74 and 79 on days one and two, respectively.

 He expressed satisfaction with the round especially after day two, saying "After yesterday (Friday), I would say that it could have only gotten better today (Saturday) and obviously it was better. Two under but as with most of what I have done this week there were always shots that I felt that I could have done better with or putts that I could have made but I am just happy to have bounced back today."

 His scorecard showed one eagle, three birdies and three bogeys.

Dr Mark Newnham, who was in second place on day two, dropped to third after scoring six over par 78 for a three-day total of 228.

Mention must be made of 15-year old Aman Dhiman, who posted the lowest score of the championship so far, a four-under-par 68.  He sunk five birdies on holes 1, 2, 4, 7 and 16 before bogeying the 10^th hole.

The perennial ladies’ national champion Jodi Munn-Barrow, who led from day one is again the national champion.  The female championships ran over three days and she posted scores of 72, 77 and 74 for a total of 223 to be leagues ahead of second-place Samantha Azan who shot 82 on the final day for a total score of 251.  Third place went to Winni Lau.  She shot 91 for an overall score of 271.

 "Happy with my overall performance today (Saturday). (I) was able to focus and just play the holes as they came, played a shot at a time and happy to finish with two over,” she said.

“Seven over for the three days so I am pleased with the overall performance and happy once again I was able to become the national amateur champion."

The Ladies 13 - 24 category went to Valerie Grant 102 (308) followed by Suzan White 108 (324).

The Men 7-12 category had two golfers with scores of 86 for Thajae Richards for a total of 252 and who still leads Richard White, who shot 89 and now totals 279.

There is a new leader in the Men Senior 0-12 category with former Cricket West Indies president Dave Cameron 81 (245), ahead of Tony Allison 83 (245) in second and Vikram Dhuman 78 (245) in third.

The Men Super Senior 0-12 also has a new leader in Mike Boyd 74 (235), followed by George Hugh with an 82 (240) and the day-one leader, former JGA president Wayne Chai Chong shot 81 (240).

The final male category - Men Super Senior 13 and over, with one occupant - Desmond Brown scored 93 for a three-day total of 282.

The juniors who competed over two days which ended on Saturday saw Sebastian Azan copping the Boys 14-15 category with scores of 78 and 81 for a combined score of 159.  Ryan Lue took second spot after posting 82 and 79 (161) while Trey Williams was third 87, 79, (161).

Michael Lowe topped the Boys 16-17 category.  He had scores of 85 and 87 (172).  Zaniel Knight was second with scores of 91 and 89 (180) while Justin Wainwright 116 and 124 (240) was third.

Phil Mickelson's dream week at the US PGA Championship continued Saturday, putting him in position to become golf's oldest major championship winner. 

The 50-year-old survived early on the back nine to shoot 70 and hold a one-stroke lead over Brooks Koepka at seven under par for the tournament. 

He knows he does not have many chances left to collect his sixth major title, but he said he's trying to keep his focus on his game rather than thinking about the big-picture implications. 

"I think that because I feel or believe that I'm playing really well and I have an opportunity to contend for a major championship on Sunday and I'm having so much fun that it's easier to stay in the present and not get ahead of myself," Mickelson told reporters. 

Mickelson opened a gap on the field early on moving day with birdies on four of his first seven holes, then another at the 10th. 

"I felt I had a very clear picture on every shot, and I've been swinging the club well, and so I was executing," he said of that stretch. "I just need to keep that picture a few more times."

The picture got a bit fuzzy at 12 and 13, where Mickelson went bogey-double bogey. 

He said his focus slipped on those two holes. 

"It's just an example of losing the feel and the picture of the shot, and I get a little bit jumpy, a little bit fast from the top, and it just -- when that happens I get narrow and I end up flipping it," he said. 

"So those two swings were more a product of not staying or keeping the feel and the focus of the shot. And so that's just a small little thing that I need to iron out."

Mickelson finished the round with five consecutive pars to ensure his place atop the leaderboard heading into Sunday. 

His remarkable week has put him in position to surpass Julius Boros, who won the 1968 PGA at age 48, as the oldest major winner, but Mickelson was in no mood to ponder what he already had accomplished just by getting this far. 

"I'm more focused on a few things that I need to work on tonight before tomorrow's round, and I'm not really dwelling back on what took place today," he said. 

"I just know I'm having a lot of fun and I'm very appreciative of the way the people have been supportive."

Brooks Koepka is exactly where he expects to be heading into the final round of a major, particularly the US PGA Championship. 

After carding a two-under-par 70 on Saturday, Koepka sits one stroke back of leader Phil Mickelson at six under for the tournament, putting him in position to win his fifth major championship. 

Considering Koepka has been no worse than tied for fourth after 12 of the last 13 rounds at the PGA, his spot in Sunday's final pairing is familiar territory. 

"It just feels good, feels normal," Koepka told reporters after his round. 

"It's what you're supposed to do, what you practice for.

"I'm right where I want to be, and we'll see how tomorrow goes.

"Just be within three of the lead going into the back nine and you've got a chance."

Koepka trailed Mickelson by five strokes at one point Saturday but saw the five-time major winner slide back to him on the back nine. 

A bogey on 18 denied Koepka a chance to match Mickelson at seven under, but the 2018 and 2019 PGA winner is looking forward to a potential one-on-one showdown in the final round. 

"I can see what he's doing, and everybody else is in front of me, so I'll have a good idea on the leaderboard what's going on and just need to putt better -- simple," Koepka said.

"If I strike it anything like I did the last three days, I'll have a chance."

If he can pull it off, Koepka would become the first player to win the same major three times in a four-year stretch since Tom Watson captured the Open Championship title in 1980, 1982 and 1983.

Though the wind that had made scoring difficult at Kiawah Island's Ocean Course the first two days died down a bit Saturday, Koepka anticipates a challenging final round. 

"it's a tough golf course," he said. "I thought it definitely played easier for sure, but this golf course you can make one little mistake and it can be costly.

"That's why it's a major championship. I think this place is perfect for it, and it will be fun to watch tomorrow."

Phil Mickelson and Brooks Koepka both shot 70 Saturday to set up a mouth-watering final pairing at the US PGA Championship. 

At seven under par for the tournament, Mickelson holds a one-stroke lead over his countryman entering the final round at Kiawah Island's Ocean Course after saving par on 18 while Koepka bogeyed the last. 

The 50-year-old Mickelson is the fourth player aged 50 or older to lead a major after three rounds in the modern era, which began in 1934. 

The others were Tom Watson at the 2009 Open Championship, Greg Norman at the 2008 Open, and Julius Boros at the 1973 US Open -- none of whom ended up holding on for the win. 

Mickelson has been resilient this week in South Carolina, though, steadying himself Saturday after going bogey-double bogey on 12 and 13 to make par on the final five holes. 

While Mickelson's resurgence has excited the fans, Koepka remains a model of consistency at the PGA.

He has finished at least tied for fourth in 12 of the last 13 rounds at the major, and he could become the first player to win the same major three times in a four-year stretch since Watson won the Open in 1980, 1982 and 1983.

Mickelson will be shooting for his sixth major title and first since the 2013 Open, while Koepka seeks his fifth. 

Louis Oosthuizen, who shared the lead with Mickelson entering play Saturday, managed just three birdies on the day on the way to an even-par 72 that left him five under for the tournament. 

American Kevin Streelman (70) is at four under, while Oosthuizen's South African countrymen Branden Grace and Christiaan Bezuidenhout are at three under after even-par rounds of their own. 

Bryson DeChambeau (71) was unable to gain ground on the leaders and enters Sunday five back of Mickelson along with Gary Woodland (72) and Joaquin Niemann (71). 

Jordan Spieth matched Billy Horschel for the low round of the day with a 68, and he sits at even par for the tournament along with Rickie Fowler (69) and Keegan Bradley (72).

Reigning Masters champion Hideki Matsuyama fell from contention with a 76, putting him at one over with the likes of Shane Lowry (73), Padraig Harrington (73) and Ian Poulter (73). 

Phil Mickelson reached the turn at Kiawah Island's Ocean Course four shots clear of his nearest US PGA Championship rivals, before sinking a birdie on the 10th.

Mickelson – a PGA championship winner in 2005 – was in sensational form in South Carolina over the first two days and carried the same level of performance into Saturday's play.

He was four under through the first eight holes, though did make his first mistake of the day on the ninth, dropping his drive short and left of the green, but recovered to make par.

That had him on 32 through nine, with Louis Oosthuizen, tied for second on five under, going through in 36.

Tied with Oosthuizen were Masters champion Hideki Matsuyama and Branden Grace, while Brooks Koepka was at four under when reaching the turn, but nosed himself up to T2 with a 12-foot putt.

But the chasing pack were further behind when Mickelson rolled a birdie putt in on the 10th to move to 10 under.

Justin Burrowes shot a three-under-par score of 69 Friday to extend his lead to eight strokes on day two of the Alliance National Amateur Golf Championship at the Caymanas Golf Club.

Following his opening-round score of 73 on Thursday, Burrowes, the only golfer to post an under-par score so far in the championship, has a two-day score of 142.

Dr Mark Newnham is currently in second place following his second-round score of 74, for a combined score of 150. Newnham shot a 76 in the first round that had left him fourth on the leaderboard.

Meanwhile, defending champion William Knibbs is a further three strokes back after a particularly rough round.  He shot 79 to go along with his 74 on day one for a two-day total of 153, 11 strokes off the leader.

Burrowes believes consistency was key to his play on Friday.

“Today (Friday) was, I would say kind of more of the same as yesterday (Thursday).  I just felt like I made more putts today, definitely driving it well, hitting it well, doing all the parts of the game pretty well right now,” said Burrowes, who made three birdies on the front nine as well as two more on the back that were cancelled by two bogeys.

 “It was just about execution and today I went out and executed pretty well.  Still, something to build on, I still missed a few putts I thought I should have made but all in all the conditions today were pretty tough with the rain and the wind.  I felt like I managed it pretty well but still I know I left a couple out there and tomorrow (Saturday) that's what I am going go after."

Among the ladies, day one leader Jodi Munn-Barrow held her lead after shooting five over par 77 on day two.  Her round included three bogeys and a double bogey for a combined total of 149 (72 and 77). "Today was also another difficult day.  It started out being very hot and extremely windy and then the rains came.  We had to stop and then go back on the course so it was very difficult to maintain concentration,” she said.

“(The) course played tough again but overall pleased with my game. I felt like I kept it together well for the 18 holes even with the distractions that were there, so I am hoping I can do the same tomorrow and put up another good score."

Second place Samantha Azan shot 16 over for an 88 to close day two on 169.  She is followed by Winni Lau, who shot 90 on both days for a total score of 180.

Scores for the Ladies 13 - 24 category are Valerie Grant 105 (206) and Suzan White 110 (216).

The Men 7-12 category had two golfers with scores of 78 for Thajae Richards for a total of 166 who still leads Richard White, who shot 93 and now totals 190.

There is a new leader in the Men Senior 0-12 category with Tony Allison 80 (162) ahead of former Cricket West Indies president Dave Cameron 77 (164) in second and Vikram Dhuman 90 (170) copping the third spot.

The Men Super Senior 0-12 also has a new leader in George Hugh with a 76 (158).  The day one leader, former JGA president Wayne Chai Chong shot 80 (159), while Robert Chin 79 (160) is in third.

 The final male category - Men Super Senior 13 and over, with one occupant - Desmond Brown scored 92 for a two-day total of 189.

The golfers will tee off at 7:30 am on Saturday.

Phil Mickelson and Louis Oosthuizen topped a leaderboard filled with major winners at the US PGA Championship, setting up a fascinating weekend at the Ocean Course at Kiawah Island. 

Mickelson started early and roared to the finish, carding five birdies on the back nine on the way to a 69 that left him at five under par for the tournament before Oosthuizen shot 68 in the afternoon for a share of the overall lead. 

Two-time US PGA winner Brooks Koepka (71) was one stroke back after recording a pair of eagles on Friday, followed by 2021 Masters champion Hideki Matsuyama (68) at three under. 

Oosthuizen's fellow South Africans Branden Grace (71) and Christiaan Bezuidenhout (70) also were two back of the leaders. 

First-round leader Corey Conners (75) and 2019 U.S. Open winner Gary Woodland (72) were at two under, with reigning U.S. open champion Bryson DeChambeau (71) dropping back to one under after a bogey on 18. 

Players battled windy conditions throughout the day and had an especially difficult time with the last two holes.

Oosthuizen lost his chance to stand alone atop the leaderboard with a bogey on 18 that ensured no one would post a bogey-free round on the first two days of competition, while Grace dropped three strokes on 17 and 18 to mar an otherwise stellar round.

Rory McIlroy (72) saw a move for contention disintegrate with bogeys on the final three holes that left him eight back of the leaders entering Saturday, and Jordan Spieth (75) was in the same spot after bogeys at 17 and 18.

The four-time major champion Koepka had perhaps the most erratic day of any contender, carding just one birdie to go with his eagles at the seventh and 11th and four bogeys. 

Among the notables missing the five-over cut line by one stroke were Dustin Johnson (74), Sergio Garcia (73), Adam Scott (72) and Justin Thomas.

Former major winners also missing out on the weekend include Zach Johnson (78), Jason Dufner (81), Martin Kaymer (77), Rich Beem (77), Charl Schwartzel (79) and John Daly (86). 

The 2009 US PGA Championship winner, Y.E. Yang, was disqualified after signing an incorrect scorecard but would have missed the cut anyway. 

Phil Mickelson played himself right into contention to become the oldest major champion in history after taking the clubhouse lead on day two of the US PGA Championship.

The 50-year-old looked in good shape in his first round on Thursday and he went a step further on Friday, finding himself top of the leaderboard having gone around the Ocean Course at Kiawah Island in 69.

It meant the American was on five under for the tournament, and he was leading by two shots shortly after he had finished for the day.

For much of Friday it looked as though Branden Grace was going to be in charge, the South African sitting pretty at six under for the tournament as he stepped up to the tee on the 17th.

But he finished his round with a double-bogey and a bogey as the breezy conditions took their toll on the two holes regarded as the toughest on the entire course, meaning he walked off after his final hole three under for the tournament.

Mickelson had similar issues on the same two holes earlier in the day after starting on the 10th, though the five-time major winner only dropped two shots across the 17th and 18th – it clearly was not enough of a wobble to really impact his mood.

The 2005 US PGA Championship winner has not had a single top-10 finish on the PGA Tour this season, but he has a great chance to end that here.

Opening up on his brilliant start at Kiawah Island, he said: "Physically I've felt as good as ever, I've been able to perform to play the shots, but I haven't been able to be as present or sharp mentally to visualise the shots I want to play.

"Meditation has been a big part of me being able to play the shots I want. It's gotten more difficult as I've got older to focus. Your mind is like a muscle, you have to exercise.

"That's what I've been doing, some days playing [as many as] 40-45 holes to make sure I can concentrate longer than just 18."

Mickelson carded five birdies after the turn, playing a huge role in putting him into contention to surpass Julius Boros as the oldest ever major winner at 48 in 1968.

Additionally, he is the first man aged 50 or over to be in top-five contention after 36 holes at a major since 2013.

His form here is made all the more remarkable by the fact he needed a special exemption to even qualify for next month's US Open, given his current ranking of 115.

"I'm having a lot of fun," he added. "To play well, to know I'm playing well heading into the weekend, to be in contention, to have a good opportunity, I'm having a blast. I'm excited for the weekend."

Ian Poulter looked to be putting himself into contention as well only to fall apart in the latter stages of his round, carding four bogeys in his final five holes – he was previously six under for the day.

Similarly, overnight leader Corey Conners' dropped down to two under for the tournament thanks to a difficult three-over second round.

Meanwhile, world number one Dustin Johnson will almost certainly not be returning on Saturday as he followed up a shocking first day with comparatively poor two over on Friday, leaving him on six over.

Jordan Spieth faces a nervy wait, he sits at four over following a second-round 75.

Justin Burrowes overcame three bogeys to shoot a one-over-par 73 and assume the early lead at the Alliance National Golf Championships at the Caymanas Golf Club on Thursday.

Burrowes also had three birdies and an eagle on the day that gave him a one-shot lead over William Knibbs. Owen Samuda had a 75 while Zandre Roye shot a 76 to be tied with Mark Newnham. Sean Morris and Shamar Wilson are both tied on 78.

Burrowes said he was happy with his first-round score even though he bogeyed the last two holes to end the round a stroke above par.

"Today was pretty good.  I knew that I had to post a good number to keep myself in the tournament which I felt like I did today,” he said.

“Didn't putt as well as I wanted to but there are still a lot of positives to build on going into the next three days.  I feel like I played well and there is a lot to build on and with the conditions being tough, it's always good to hit the ball well which I feel like I did today and I look forward to the next couple of days."

Meanwhile, many-time women’s champion Jodi Munn-Barrow led juniors Samantha Azan and Winni Lau with an even-par 72.  She was also pleased with the day's play.

"(I am) very happy with today's round, didn't make a lot of mistakes which was good because the course was playing very tough.  Conditions were hard, so overall happy, still have two more days to go so I have to focus on day two and day three so and hopefully the outcome will be good," she said.

In the Ladies 13 - 24 category, Valerie Grant had a score of 101 while Suzan White shot 106.

In the Men Senior 0-12 category, Vikram Dhuman leads with an 80 and is followed by Tony Allison (82), Nigel Davy (84) and Dave Cameron (87).

In the Men 7-12, Thajae Richards shot 88 while Richard White had 97.

The Men Super Senior 0-12 is led by former JGA president Wayne Chai Chong (79) and is followed by Teddy Alexander (80), Robert Chin (81), Stephen Chang (81) and Bert Tomlinson (82).

 Desmond Brown scored a 97.

The golfers will take to the Caymanas Golf Course at 7:30 am today for the second day of the championship.

Brooks Koepka dismissed concerns over his knee, insisting he does not have to be "100 per cent" after impressing on day one of the US PGA Championship.

Koepka ended the opening round two strokes behind leader Corey Conners and tied for second position following his three-under-par 69 on Thursday.

American star Koepka has been plagued by injuries since winning back-to-back PGA Championships in 2019 and a fourth major title in three years, undergoing knee surgery in March before missing the cut at last month's Masters.

Koepka overcame a slow start after double-bogeying his opening hole in windy conditions as he made history in South Carolina.

The four-time major champion has opened the PGA Championship with a score in the 60s in each of the last six years, the longest such streak at any major in the modern era (since 1934), eclipsing Jack Nicklaus (five – 1972-1976 Masters).

"It's a major. I'm going to show up," Koepka said when asked about his fitness and whether it was the best he has felt since returning from injury. "I'm ready to play. I've been itching to do this since Augusta.

"I mean, I feel so much better now. I don't need to be a hundred percent to be able to play good."

"I love it when it's difficult," said Koepka. "I think that's why I do so well in the majors. I just know mentally I can grind it out. Like when it's windy like this, it's not so much putting, it's more about ball striking, and I felt like I struck it really well today. I feel like that's why I've done really well.

"You've got to understand that sometimes par is a good score. You've got to understand that 30, 35 feet is a great shot sometimes, and you've just got to accept it and move on."

Defending champion Collin Morikawa closed out day one a shot further back at two under.

Morikawa mixed five birdies with three bogeys to end the round three strokes off the pace at Kiawah Island Golf Resort.

He played alongside big-hitting Bryson DeChambeau (72) and praised the reigning U.S. Open champion.  

"I think people need to give him credit, starting today, that he's actually picking up the pace," Morikawa said. "It was amazing how fast he actually played. I'm not going to say fast, but he wasn't slow. You weren't just waiting on him to figure out whatever.

"Kudos to him because it was windy and he had to figure out some stuff for sure. But I enjoy it. He's a character. He's his own person. That's what makes Bryson, Bryson. I think that's why people love him. I enjoy playing with someone like that. It's not going to faze me that he hits it a hundred past me. I know I can still hit it and play golf."

DeChambeau, who heads into the second round tied for 31st, added: "The wind just kicked my butt. It's hot. Just grinding out there, it takes a lot out of you. Working really, really hard to hit every shot the exact way I want to, and then it doesn't happen, and you've got to be comfortable with it and going, okay, how do I get up-and-down.

"It's windy and you're over a four-footer. Wind is blowing really hard, and you think it's going to break. When the wind stops, it's not going to break. It's all just a really difficult thing that you've got to control out there. It's a lot of work."

Corey Conners savoured his "really special round" after defying windy conditions to set the early pace at the US PGA Championship.

Conners earned a two-shot lead on Thursday, the unheralded Canadian golfer upstaging a star-studded field with a five-under-par 67 in South Carolina.

Without a victory since his solitary PGA Tour triumph at the 2019 Texas Open, Conners was almost flawless in gusty conditions, holing six birdies with just one bogey.

Conners' lead marks his third career 18-hole lead/co-lead on the PGA Tour (0-for-two to date) and first at a major. Earlier this season, the 29-year-old was tied for the first-round lead at the Arnold Palmer Invitational and finished third – his best result of the season.

"It was a really special round. I did a lot of things really, really well. Like I said before, it's really nice to see some mid-range birdie putts fall in the hole," Conners said.

"Really gave me confidence and felt like I rolled it really well for the rest of the round. A lot of putts had chances to go in and I made some nice saves, as well."

Prior to Thursday's first round, Conners' best position after any round of a major was equal sixth through 54 holes at this year's Masters at Augusta, where he eventually finished tied for eighth.

Conners bettered that at Kiawah Island Golf Resort, where he tops the leaderboard ahead of four-time major champion Brooks Koepka, Keegan Bradley, Viktor Hovland, Aaron Wise, Sam Horsfield and Cam Davis.

"I have a lot of belief in myself, and I've been playing well for quite a while," said Conners. "I'm excited for opportunity to play against the best players in the world and put my game to the test.

"I have a lot of confidence in my game and I'm excited for the rest of the weekend. Didn't try to force it to happen but definitely saw myself having a good day today and hopefully can keep that up the rest of the weekend."

Corey Conners withstood hammering winds to claim a two-stroke lead following the opening round at the US PGA Championship as Brooks Koepka impressed but Rory McIlroy and Dustin Johnson struggled.

Prior to Thursday's first round in South Carolina, Conners' best position after any round of a major was equal sixth through 54 holes at this year's Masters at Augusta.

Conners bettered that at Kiawah Island Golf Resort, where the Canadian defied the wind to set the early pace with a five-under-par 67.

Without a victory since his solitary PGA Tour triumph at the 2019 Texas Open, Conners was almost flawless in gusty conditions, holing six birdies with just one bogey.

Conners' lead marks his third career 18-hole lead/co-lead on the PGA Tour (0-for-two to date) and first at a major. Earlier this season, the 29-year-old was tied for the first-round lead at the Arnold Palmer Invitational and finished third – his best result of the season.

Koepka ended day one in a share of second position alongside Keegan Bradley, Viktor Hovland, Aaron Wise, Sam Horsfield and Cam Davis.

Koepka has been plagued by injuries since winning back-to-back PGA Championships in 2019 and a fourth major title in three years – the American star underwent knee surgery in March before missing the cut at last month's Masters.

But Koepka impressed on Thursday, overcoming a slow start to shoot a three-under-par 69.

Koepka double-bogeyed his opening hole on the back nine, however, the four-time major champion only dropped one shot after that as he tallied six birdies.

He has opened the PGA Championship with a score in the 60s in each of the last six years, the longest such streak at any major in the modern era (since 1934), eclipsing Jack Nicklaus (five – 1972-1976 Masters).

Defending champion Collin Morikawa is a stroke further back alongside the likes of five-time major winner Phil Mickelson.

Big-hitting American and reigning U.S. Open champion Bryson DeChambeau signed for an even-par 72 at the close of the first round, level with Jon Rahm and Justin Rose, while Masters holder Hideki Matsuyama, former world number one Jordan Spieth – eyeing a career Grand Slam – and Xander Schauffele shot 73s.

Jason Day and Patrick Reed were also further down the leaderboard as two-time PGA Championship winner McIlroy and world number one Johnson were powerless in the wind.

McIlroy – seeking a first major trophy since 2014 – recorded a three-over-par 75, which included six bogeys and just three birdies.

Justin Thomas also went three over for the day, while Johnson finished with two double-bogeys and a bogey in a forgettable four-over-par 76 display.

Rory McIlroy struggled on his return to Kiawah Island with a three-over-par 75 in the opening round at the US PGA Championship as playing partner Brooks Koepka impressed.

McIlroy won by eight shots the last time the PGA Championship was staged at Ocean Course in South Carolina in 2012 and was installed as the favourite of many after ending a winless streak of almost two years at the Wells Fargo Championship two weeks ago.

However, the four-time major champion – seeking a first major title since 2014 – landed his very first shot into the water on a windswept morning before recovering somewhat with back-to-back birdies on Thursday.

McIlroy – a two-time PGA Championship winner – was level par at the turn after dropping another shot on the par-five 16th, but he managed just one more birdie compared to five bogeys as he closed for 75, eight shots behind Corey Conners.

Koepka played down expectations heading into the tournament due to a knee injury and he started slowly with a double-bogey on his first hole, though the two-time PGA Championship winner recovered well with two birdies in the next three holes.

After turning in 36, Koepka picked up three shots in four holes on the front nine to complete an impressive turnaround that saw him earn a share of the lead before Conners soared to the summit as he aims to add to his successes in this event in 2018 and 2019.

"I felt like an idiot," he told Sky Sports Golf when reflecting on his cagey start. "It was probably a poor club choice off 10. I thought three-wood would have carried, but it didn't. I also didn't find the face, it barely hit the face!

"The first rule is, if you're in trouble, get the hell out. I couldn't reach the green and it was a bad lie, so I didn't know where I was going. I just tried to hit a sand-wedge up by the green instead of just chopping it out.

"So it was a mental mistake there, and I deserved every bit of that double-bogey. But it kind of helped me refocus. I can't play with any mistakes, maybe one a day, and that was my one, and I got it out of the way on the first hole."

Koepka is joined on three-under par by former champion Keegan Bradley, Viktor Hovland. Aaron Wise and Sam Horsfield.

Bradley's opening round included four birdies and just one dropped shot, coming on the par-four 13th, while Hovland bounced back from an opening bogey with four birdies.

Collin Morikawa is one shot further back after bogeying his final hole, the defending champion joined on a first-round 70 by Martin Laird, who was also let down by a couple of dropped shots on his final two holes.

Justin Thomas finds himself way down the standings, meanwhile, after carding a three over that included a double-bogey on the 18th, while US Open champion Bryson DeChambeau had a mixed first day as he posted a level-par 72.

World number one Dustin is among the late starters, along with Jordan Spieth, Tommy Fleetwood and Justin Rose.

Major glory awaits for one man at Kiawah Island on Sunday, when the winner of the US PGA Championship will be confirmed.

With such a stacked field it is hard to pick out the most likely victor, but that has not stopped Stats Peform's team of expert writers from having a go.

Last year it was Collin Morikawa who prevailed, snapping American compatriot Brooks Koepka's run of consecutive wins.

Who will it be this time?

IT'S OFFICIAL, RORY IS BACK! – Peter Hanson

Okay, I'm officially calling it – Rory McIlroy is back! At the back end of 2019 and the start of 2020, the Northern Irishman was flying. Then the coronavirus pandemic hit. Then there were some questionable decisions to start trying to match the bombs Bryson DeChambeau can nail off the tee. Then there were some ugly results – including missed cuts at the Players Championship and the Masters. But forget all that, McIlroy – just six weeks on from starting work with renowned coach Pete Cowen – was back in the winners' circle at Quail Hollow last weekend, his first title since November 2019. A McIlroy in full swagger is a joy for any golf fan, and crucially he knows how to get it done at Kiawah Island having won the first of his two PGA Championship titles at the South Carolina course back in 2012 – doing so by eight strokes, a record for the tournament. It's time for Rory to finally get that fifth major.

SCHAUFFELE HAS GOT THIS ONE – Russell Greaves

If you have this notion that Xander Schauffele always seems to be in contention at the majors, it's because he is. His tie for third at the Masters this year represented an eighth top-10 finish at a major for Schauffele, with two of those coming at the US PGA. His record is one of remarkable consistency, with only one missed cut across 14 entries in the sport's four headline events. Schauffele is one of the most adaptable players out there, as evidenced by his PGA Tour-leading sand save percentage of 69.35. At just 27, it seems inevitable he will eventually clinch a title at one of those quartet of tournaments.

HIDEKI WILL DOUBLE UP – Ben Spratt

Hideki Matsuyama had been waiting a long time for his breakthrough triumph at Augusta last month, with seven top-10 finishes at majors without reaching the winner's circle before that Masters victory. "It was a relief, really," he said last week. But having got that monkey off his back and shown he is good enough in his approach play that a poor putting game need not be a hindrance, Matsuyama can no longer be written off so easily. The Japanese will be heading to Kiawah Island full of confidence and ready to win. A second straight success would really lay down a marker.

IT'S RAHM TIME – John Skilbeck 

Sooner or later, or so goes the theory, Jon Rahm will win a major. Let's tilt towards sooner then, because Rahm is top of the PGA Tour's ball-striking chart this season, fourth in terms of finding greens in regulation and top 20 in average driving distance and scoring average. On a course set to measure over 7,800 yards, those ingredients in his game look more than useful, but Rahm will need to putt well too and that is not a given. He is down in a share of 192nd for putts per round this season, so needs to get something going with the short stick. He is developing a reputation as a Masters specialist, with four successive top-10 finishes at Augusta, and the Kiawah Island conditions will be a world away from those in Georgia. But this breakthrough at a major is going to happen sooner or later, isn't it?

RAHM'S THE ONE FOR ME – Chris Myson 

Aside from a tie for fourth at the 2018 US PGA Championship, Rahm has not made a huge impact at this event. But he is rightly among the favourites for victory this week on the back of his tie for fifth place at the Masters and his continued consistency on the PGA Tour. With six top-10 finishes to his name at major championships, Rahm has proven he can get himself into contention at the biggest events. And he comes into the latest major in form. While the world number three is yet to win this year, he has missed the cut just once in 10 events. Rahm says the recent birth of his son Kepa has helped to take the pressure off his pursuit of a first major, an occasion which is surely not far away.
