Louis Oosthuizen holds a two-shot lead at the halfway stage of the 149th Open Championship after posting a record 36-hole score at golf's oldest major.

The South African, who claimed the Claret Jug in 2010, continued his stunning form at majors in 2021 with a 65 on Friday, with 129 the lowest total after two rounds at this event.

Tournament debutant Collin Morikawa, who had earlier carded a 64 at a sun-drenched Royal St George's, is Oosthuizen's closest rival on nine under, with 2017 winner Jordan Spieth one stroke further back.

Oosthuizen finished in a tie for second at the US PGA Championship in May and was outright runner-up at the U.S. Open the following month. 

He faces stiff competition from a chasing pack that also includes world number one Dustin Johnson following his 65 to move seven under, while Brooks Koepka is on five under.

Favourable weather on the Kent coast meant the course was set fair for low scoring and 2020 US PGA Championship winner Morikawa took full advantage.

His round included a run of five birdies in seven holes before a bogey at the 15th – the tricky par four playing at an average of 4.4 – halted his progress.

Oosthuizen did not go out until the afternoon but quickly made his intentions clear with a birdie at the first, though the highlight of his round was an eagle three at the 14th.

Reigning champion Shane Lowry also enjoyed a fine day as he shot 65, while pre-tournament favourite Jon Rahm went one better to keep his slim hopes alive.

Rory McIlroy birdied the last to ease any lingering fears of missing the cut, while 2018 champion Francesco Molinari did not make the weekend after a 74 that included a quadruple-bogey seven at the sixth, where he took three shots to get out of a bunker.

SHOT OF THE DAY

There was joy for Englishman Jonathan Thomson as he hit the first ace at the 16th en route to a 67.

CHIPPING IN

Rory McIlroy: "I felt a little nervous going to that 18th tee. I knew I needed a par at least, but birdie to at least be comfortable."

Jonathan Thomson: "The hole-in-one was obviously awesome. It was a real confidence booster after what had been up until that point a real grind."

A LITTLE BIRDIE TOLD ME...

- Jordan Spieth's halfway score of 132 is the American's second lowest at a major.

- Emiliano Grillo shot a 64, which was six strokes better than his opening round.

- Phil Mickelson improved on his opening effort by eight strokes, but still missed the cut at 12 over.

Collin Morikawa feels has the right mindset to cope with the pressure of majors after he took the lead at the Open on Friday with a fine 64.

The debutant surged up the leaderboard with a tremendous second round, moving to nine under for the tournament.

A stunning card from the 2020 US PGA Championship winner showed just one bogey and he could have even moved further clear had a putt on 18 not skirted the cup.

Morikawa made seven birdies as he took advantage of fine early conditions at Royal St George's.

As well as his US PGA win, Morikawa, 24, also has a 2021 top-10 finish to his name at that tournament, as well as coming fourth at the U.S. Open last month.

"Yeah, I look at them as obviously they're starred," he said of his success at majors so early in his career.

"We have four of them a year, and you're trying to definitely win these four because they're that big. 

"Talking about last year's PGA, I had seen every single guy before, I had played with every single guy, and that doesn't make anything different. 

"It's just the stage that we're on, more media, more spectators, more people around. 

"But that's everything outside that I could control. For me, it's just let's go figure out this golf course Monday through Wednesday like I have been the past couple years and figure it out on what I need to do to play well. 

"This style of golf is very different, but playing last week at the Scottish Open helped tremendously."

Morikawa posted a 67 in round one but believes his play was similar across the first two days.

"Just sticking to what I've been doing," he said of his Friday success.

"On Thursday I thought I played really well, just wasn't hitting as many fairways. Was able to hit a few more fairways early on in the round this time."

Morikawa ended his round three clear of overnight leader Louis Oosthuizen, who was joined at six under by fellow South African Daniel van Tonder as well as Emiliano Grillo, Marcel Siem and Jordan Spieth.

A flying start from former champion Spieth, who birdied his first two holes on Friday, meant he was promptly up to seven under and within two of his American compatriot, though he then dropped a shot at the third.

Birdies on 17 and 18 meant Grillo matched Morikawa with a 64, while Siem also gained two shots in the final two holes to sign for an impressive 67.

Rory McIlroy, meanwhile, all but ensured he will finish above the cut line with a crucial birdie on 18.

The Northern Irishman is level par for the week after a second straight 70. 

In an up-and-down round two, he recovered nicely from consecutive bogeys to start his day but then bogeyed 16 and 17 before improving his position once more at the last.

Tournament debutant Collin Morikawa surged into the lead at The Open with a second-round 64 to move to nine under on Friday.

The 2020 US PGA Championship winner's stunning card showed just one bogey as the American ended his round three clear of overnight leader Louis Oosthuizen.

Morikawa made seven birdies as he took advantage of fine conditions at Royal St George's, but he squandered the chance to get to 10 under with a putt on 18 that skirted the cup.

Daniel van Tonder moved level with South African compatriot Oosthuizen following a 66, while Tony Finau signed for the same score to get to four under.

Rory McIlroy, who matched Finau's 70 on Thursday, remained at even par through 11, while 2018 Champion Golfer of the Year Francesco Molinari is unlikely to make the weekend after a 74 left him two over.

Oosthuizen goes out at 14:59 local time alongside reigning champion Shane Lowry and pre-tournament favourite Jon Rahm, both of whom will be looking to improve on rounds of 71.

As if to welcome the return of this glorious tournament after two years in the dark, the sun shone brightly on the opening round of the 149th Open Championship.

Royal St George's was initially basked in a warm glow as a crowd of more than 30,000 were treated to a spectacular day of golf at the famous links in Sandwich.

Louis Oosthuizen closed the round top of the leaderboard, but it was the course itself that took centre stage.

And Stats Perform's man on the ground was out and about, taking notes of all the happenings on the other side of the ropes.

SEAVIEW AND FREEVIEW!

There is a large grass mound at the far end of the course that affords a stunning vantage point across the whole links.

A sizeable crowd gathered there from early in the morning, taking in the view from high above the sixth green, with the North Sea glistening in the sunshine away to the east.

But there is another option, with Princes Drive running alongside the course but outside of its perimeter and allowing an unobstructed view of the fifth green, while the sea is a stone's throw away, with plenty of projectiles available on Sandwich Bay's pebble beach.

DINO-SOARING TEMPERATURES

Fancy dress is a common sight at golf tournaments but you should choose your outfit wisely.

The weather forecast in Kent is promising to serve up the best of British summertime over the four days of competition and it made one man's decision to don a dinosaur onesie appear quite ill-judged.

He was to be found roaming the fairway's edge around the seventh hole, and would no doubt soon have been in search of water. Or maybe he was just waiting for Roary McIlroy...

FAN-TASTIC

It was a joy to see so many fans in attendance in Sandwich, with several players commenting on how much it improved the experience for them.

After a prolonged spell of being deprived of such things, Jordan Spieth was among those to welcome the return of crowds to enhance the spectacle.

He said: "I feel like the fans here are very knowledgeable about the sport, and they're also having a great time.

"It's just like at Augusta, it's just a beautiful setting a lot of times, shaping a lot of the holes with people."

Louis Oosthuizen holds the first-round lead at The Open but has Jordan Spieth snapping at his heels in a battle between two former champions.

South African Oosthuizen, who claimed the Claret Jug in 2010, shot a blemish-free 64 to sit one stroke ahead of 2017 winner Spieth, who has Brian Harman for company on five under.

Oosthuizen outshone his playing partners in a headline-grabbing trio featuring reigning champion Shane Lowry and pre-tournament favourite Jon Rahm.

A host of players are within three shots of the summit at Royal St George's, including major winners Justin Rose and Danny Willett, along with 2009 champion Stewart Cink.

Lowry's hopes of becoming the first player to successfully defend the title at the Sandwich links since Harry Vardon in 1899 suffered a setback following an opening 71, with U.S. Open champion Rahm matching that effort.

While Oosthuizen holds a narrow advantage, it is three-time major winner Spieth who has the omens on his side, having been drawn in the same group as Branden Grace.

Oosthuizen's compatriot has featured alongside the eventual winner in the opening two rounds of each of the last two editions of golf's oldest major.

World number one Dustin Johnson is poised to make a move after a two-under-par 68, with Sergio Garcia signing for the same score.

Rory McIlroy, who missed the cut on home soil at Royal Portrush two years ago, closed with a birdie to card an even-par 70.

SHOT OF DAY

It was not the most technically brilliant strike of the ball, but the nerves involved in Richard Bland's opening tee shot made it a triumph of coolness under pressure.

The Englishman won his first European Tour title at the 478th attempt at the British Masters in May and had the honour in Kent on Thursday.

He managed to keep the ball on the fairway with a drive that was slightly left, but safe nonetheless.

CHIPPING IN

Louis Oosthuizen: "[That was] probably in my mind the perfect round I could have played. I didn't make many mistakes. When I had good opportunities for birdie, I made the putts."

Richard Bland: "It was very special, very nerve-racking. The nerves definitely cranked up a little bit and I was glad to hit one in the fairway." 

Shane Lowry: "It's so good to have the crowds here and it's so good to be playing in the Open Championship like we know. The big grandstands and the big crowds and getting clapped on the grandstands and on the tees, that's pretty cool."

A LITTLE BIRDIE TOLD ME...

- Louis Oosthuizen's 64 is his lowest score at a major.

- Rory McIlroy started an Open with a birdie for the first time, with this the Northern Irishman's 12th entry into the tournament.

- The 15th hole proved the toughest to tame on Thursday, the par four playing at an average of 4.37.

Jordan Spieth staked an early claim for a second Open title with a stunning first-round 65 at Royal St George's.

The three-time major winner, who triumphed at Royal Birkdale in 2017, was in fine form on Thursday as he reached five under to sit one stroke behind fellow former Champion Golfer of the Year Louis Oosthuizen. Oosthuizen was still out on the course.

Spieth has the good fortune to be playing alongside Branden Grace, who has featured with the eventual winner in the opening two rounds of the previous two Opens.

The South African teed off in a group with Francesco Molinari at Carnoustie in 2018, before playing alongside Shane Lowry at Royal Portrush a year later.

Spieth's showing put him two ahead of the next-best clubhouse score, with four players on three under.

Reigning champion Shane Lowry and pre-tournament favourite Jon Rahm both faced an uphill battle to get involved in the race for the Claret Jug.

Irishman lowry was one over through 16, with U.S. Open champion Rahm one stroke further back at the same stage.

Rory McIlroy tees off at 15:21 local time with the hotly tipped Patrick Reed for company.

The 149th Open Championship got under way at Royal St George's on Thursday, with Jon Rahm the hot favourite to prevail.

Englishman Richard Bland, who won his first European Tour title on his 478th start at the British Open in May, had the honour of teeing off proceedings at 06:35 local time at the Kent links, which is hosting for the 15th time.

Rahm claimed his maiden major with victory at this year's U.S. Open and will attempt to wrestle the Claret Jug from the grasp of playing partner Shane Lowry, with 2010 Champion Golfer of the Year Louis Oosthuizen completing a trio that tees off at 09:58.

Lowry, who is aiming to become the first player to successfully defend the prize at this course since Harry Vardon in 1899, proved a popular winner at Royal Portrush two years ago, with the 2020 event having been cancelled amid the coronavirus pandemic.

Spaniard Rahm is eyeing a rare double, with only six players having won the U.S. Open and Open Championship in the same year.

The omens bode well for the in-form Jordan Spieth after he was drawn alongside Bryson DeChambeau and good-luck charm Branden Grace.

Grace has played with the eventual winner in his first two rounds at each of the previous two Opens.

The South African featured with Francesco Molinari at Carnoustie in 2018 and Lowry in Northern Ireland the following year. 

Four-time major champion Rory McIlroy will head out in the afternoon with Patrick Reed and Cameron Smith, while world number one Dustin Johnson starts his bid for a first Open title at 10:20 with Will Zalatoris and Justin Rose for company.

Brooks Koepka is an 08:45 starter and the star attraction of a threesome that includes Jason Kokrak and Garrick Higgo.

Darren Clarke, who prevailed when last Royal St George's last hosted in 2011, goes out at 08:25 alongside Bernd Wiesberger and amateur Joe Long.

U.S. Open winner Jon Rahm will tee off alongside 2019 Champion Golfer of the Year Shane Lowry at the 2021 Open Championship on Thursday.

Spaniard Rahm won his maiden major at Torrey Pines, edging out Louis Oosthuizen by one stroke, and is among the favourites to prevail at Royal St George's this week. 

Lowry was a popular winner when golf's oldest major was held at Royal Portrush two years ago, with the 2020 event having been cancelled amid the coronavirus pandemic.

The Irishman, whose trio goes out at 09:58 local time and also includes 2010 victor Oosthuizen, will seek to become the first man to defend the Claret Jug at the Kent links since Harry Vardon in 1899.

Any superstitious players might have hoped to be drawn in Branden Grace's group, as he has played with the eventual winner in his first two rounds at each of the previous two Opens.

The South African featured with Francesco Molinari at Carnoustie in 2018 and Lowry in Northern Ireland the following year. 

Jordan Spieth, a winner in 2017, and 2020 U.S. Open champion Bryson DeChambeau are the lucky pair, with that group teeing off at 09:25.

Four-time major champion Rory McIlroy will head out in the afternoon with Patrick Reed and Cameron Smith, while world number one Dustin Johnson starts his bid for a first Open title at 10:20 with Will Zalatoris and Justin Rose for company.

Brooks Koepka is an 08:45 starter and the star attraction of a threesome that includes Jason Kokrak and Garrick Higgo.

Darren Clarke, who prevailed when last Royal St George's last hosted in 2011, is an 08:25 starter alongside Bernd Wiesberger and amateur Joe Long.

The action will begin at 06:35, with English trio Richard Bland, Andy Sullivan and Marcus Armitage having the honour.

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."
