The sporting calendar provides many memorable days throughout the year but rarely do elite events overlap as often as at the Olympics.

At this year's delayed Tokyo Games, there is the prospect of seeing several of the world's top athletes all competing for gold at the same time.

August 1 looks a good bet for the standout day in 2021.

The final round of the men's golf event could see Rory McIlroy and Jon Rahm in the mix, with Andy Murray hopeful he will meanwhile be defending consecutive singles gold medals in the tennis.

This comes on the same day that Simone Biles could potentially become the most decorated Olympic gymnast of all time.

As if that were not enough, the men's 100m final is another must-watch event.

Expectations will be high heading into that second Sunday of the Games, with examples from the past three competitions living up to their billing...

AUGUST 16, BEIJING 2008

Michael Phelps and Usain Bolt would be firmly in contention to appear on the Games' own Mount Rushmore and each enjoyed one of the finest moments of their respective careers on the same day.

Phelps had spent the opening week of the Beijing Olympics pursuing Mark Spitz's 1972 record of seven golds and had six as he entered the pool again for the 100m butterfly final, almost 12 hours before Bolt's big moment.

Seventh at the turn, the United States superstar needed a remarkable recovery to triumph over a devastated Milorad Cavic by 0.01 seconds.

Phelps would pass Spitz with his eighth gold of the Games the following day, by which point he was sharing the headlines with Jamaica's own ultimate athlete.

Bolt's blistering 9.69-second final triumph in the 100m stood as a world record until the same man beat it exactly a year later. The new benchmark remains unmatched.

And that Saturday in China also saw the small matter of Roger Federer's only gold medal, claimed alongside Stan Wawrinka in the doubles final after falling to James Blake as the top seed in the singles.

AUGUST 4-5, LONDON 2012

It is actually tough to choose just one day from the 2012 Olympics, where this weekend delivered from start to finish.

On the Saturday evening, at the Aquatics Centre, swimming prepared to say goodbye to its greatest name. Phelps and the United States won the 4x100m medley, clinching his 18th gold medal in what appeared set to be his final race.

Indeed, Phelps confirmed his retirement following the Games, only to return in predictably dominant fashion in 2016.

Across the city that same night, Team GB athletes were capping a stunning run of medals that would see the day dubbed "Super Saturday". There were six home golds in all, including big wins for Jessica Ennis, Greg Rutherford and Mo Farah in quick succession.

The drama only continued the next day, too, as Murray finally sealed a Wimbledon win over Roger Federer in the tennis event, while Bolt lit up London Stadium in the 100m.

AUGUST 14, RIO 2016

Although there will be no Bolt brilliance in Tokyo, Brazil was treated to another show as he became the first three-time winner of the 100m – later doing likewise in the 200m.

The first triumph was almost overshadowed on the track, however, coming shortly after Wayde van Niekerk had broken Michael Johnson's 17-year 400m world record by 0.15 seconds.

Again, the excitement was not reserved for athletics, with Murray in action that evening to claim another gold after coming through a four-hour epic against Juan Martin del Potro.

Murray is the only player – men's or women's – to win consecutive singles golds, while Rafael Nadal's presence added a little more stardust even though he lost the bronze final to Kei Nishikori.

A stunning Sunday also saw Biles add to the reputation she takes with her to Tokyo, a third gold on the vault making her the most decorated American gymnast.

And there was history, too, for Justin Rose, as he edged past Henrik Stenson at the 18th hole of the fourth round to become the first Olympic golf champion in 112 years.

Rising stars Justin Burrowes and Emily Mayne have been named among a 12-member team that will represent Jamaica at the Caribbean Amateur Golf Championships, scheduled for August 8-13 in Puerto Rico, where they will compete for the Hoerman Cup and George Teale Trophy, for men and women, respectively.

Justin Burrowes and William Knibbs both began the final day of the Jamaica Golf Association's (JGA) National Senior Trials at Caymanas Golf Club on Sunday on even par 216 but it was Burrowes, who took home the trophy at the end.

The leaderboard showed four birdies and a bogey on the front-nine for three under par 33. On the back-nine, he shot a birdie, two bogeys and one double bogey for a three-over-par 39, for an even-par 72.

His combined score of even-par 288 was three strokes ahead of runner-up Knibbs.

“Today (Sunday) was pretty good. I shot even par. I was three-under on the front-nine and three over on the back-nine.  I would say that I felt like I had my best game today.  I felt like I struck it the best,” he said.

“I felt like I was swinging the best today out of all the four days.  I didn't quite score like I wanted to.  I didn't quite finish like I wanted to but a win is a win and I am very grateful for it and I am thankful to my entire team around me for all the support.  It's just always an amazing feeling when you can execute and come out on top and I am just very grateful for that."

Knibbs was on target up to hole number 15 but had a double bogey on 16 and a bogey on 18 for a three-over par 75 for a total score of 291.

"My ball-striking wasn't where I wanted it to be over the course of this weekend so the last two rounds (I) missed a lot of greens with irons and short clubs which is usually the strength of my game but I just made a bad swing on 16, lost a ball, made double - just one of those things but I take a lot of positives from the past week because my ultimate goal was to break par for the four rounds and I came really close to it so I know that if I tighten up on a few things, then I should be good for the Caribbean Championships," he said.

Dr Mark Newnham with a score of 301 (78, 74, 75, 74) was third, while junior golfer, 16-year-old Rocco Lopez, who improved his position after every round, ended in fourth after the final round of 76 for an overall score of 304.

Shamar Wilson was one stroke back on 305 (77,80, 74, 74) in fifth.

Junior golfer, Emily Mayne copped the Ladies category, which she led from round one.

She posted her best round of five over par 77 in the final round for a total score of 316 (80, 79, 80, 77) to win by 32 strokes ahead of Mattea Issa who ended on 358. Many-time national champion Jodi Munn-Barrow, who was in second place, did not compete on the final day.

“Today (Sunday) was a good day.  I had a very good start which was different from the first two days which I had a bad start.  I kept it consistent,” she said.

“Obviously, I had two bad holes, which is what resulted in me shooting five over. However, the pin positions on a lot of the greens were very difficult and you had to know your way on the greens which I did not succeed in on the holes which I finished badly on, however, I am proud of myself for my finish today."

 The golfers were competing for places on team Jamaican for the Hoerman Cup for men and the George Teale Trophy for women in the Caribbean Amateur Golf Championship which is tentatively set for Puerto Rico August 8-13.

The top three golfers in the various categories in the two-day (Saturday/Sunday) Caymanas Golf Classic which ran concurrently with the national trails were:

Men & Men Senior 0-6:  Justin Burrowes - 140, William Knibbs - 145 and Dr Mark Newnham - 149.

Men & Men Senior 7-12:  Dave Cameron - 171, Gregory Mayne - 172 and Ryan Lue - 173.

Men & Men Senior 13-24: Philip Gooden - 165, Delroy Anderson - 191 and Richard Wayner - 200.

Men Super Senior 0-12:  Robert Chin - 156, Mike Boyd - 157 and Wayne Chai Chong - 160.

Men Super Senior 13.24:  George Wright 182, Fred Sutherland - 191 and Howard McKenzie - 201

Ladies 0-12:  Emily Mayne -157, Michele McCreath 173 and Winni Lau 174.

Junior Boys 11-13:  Aarron Ghosh - 165, Ramsay Wayner 177 and Kemari Morris 193.

Junior Girls 11-13:  Khatri Anoushka 188.

William Knibbs and Emily Mayne are the early leaders after Thursday’s opening day of the Jamaica Golf Association's (JGA) National Senior Trials at the Cinnamon Hill Golf Course in St. James and the Caymanas Golf Club in St. Catherine.

Graeme McDowell and Martin Kaymer have been appointed as vice-captains by Team Europe skipper Padraig Harrington for the Ryder Cup.

Both players bring a wealth experience to Harrington's backroom team for the rescheduled clash against the United States, which will take place at Whistling Straits in September – 12 months on from the original date that was scuppered by the coronavirus pandemic.

McDowell was also part of the set-up at Le Golf National in 2018, where Europe – led by Thomas Bjorn – hammered their American counterparts 17.5-10.5.

The Northern Irishman has featured four times as a player (2008, 2010, 2012, 2014), accumulating nine points from 15 matches – including claiming the winning point at Celtic Manor in 2010.

"I decided on Graeme as a vice-captain a long time ago. He was vice-captain in 2018 with me and I liked what he brought to the team room," Harrington said of the 2010 U.S. Open champion.

"He's quite an authority, confident in what he's doing and saying and knows the scene. The only reason he would not have been a vice-captain was if he was going to be a player.

"Graeme is a strong influence and the players look up to him. When he speaks, people listen, but he doesn't speak unless he's got something to say. I definitely saw that when he was vice-captain previously – players pay attention and follow him."

Kaymer too brings plenty of Ryder Cup experience to the table. The German has won 6.5 points from four appearances at the biennial tournament (2010, 2012, 2014 and 2016).

Undoubtedly his most famous contribution came when he sank the winning putt in 2012 to complete the "Miracle of Medinah", where Europe overturned a 10-6 deficit on the final day to retain the trophy.

Whistling Straits is also the scene of Kaymer's 2010 US PGA Championship triumph, which led to his debut in the Ryder Cup. 

"Martin is somebody I wanted as a vice-captain because he has a great personality and brings a calmness, a European element, and a lot of confidence with him," Harrington said of Kaymer, who also won the 2014 U.S. Open. 

"The fact that he won around Whistling Straits also brings that level of authority and assurance that you need.

"Martin will also bring a nice emotion to the team, which is very important. He's somebody who will help with the atmosphere, put an arm around a player or two and bring that level of authority and belief that we may need during the week."

Jon Rahm birdied his final two holes to outlast Louis Oosthuizen by one stroke for U.S. Open victory and his first major title.

Oosthuizen was in a three-way share of the lead heading into the deciding round and opened up a one-shot lead on a gripping final day at Torrey Pines.

But Rahm rallied in San Diego, where the emotional Spanish star dramatically birdied the 17th and 18th holes to claim a lead he never relinquished on Sunday.

Rahm signed for a four-under-par 67 to finish six under through 72 holes as 2010 Open Championship winner Oosthuizen (71) settled for a runners-up cheque.

At the scene of his maiden PGA Tour win – the 2017 Farmers Insurance Open – Rahm became the fourth player from Spain to win a major and first at the U.S. Open.

Rahm, who was forced to withdraw from the Memorial Tournament when leading by six shots after testing positive for coronavirus earlier this month, said post-round: "I'm a big believer in karma. After what happened a couple of weeks ago, I stayed really positive, knowing big things were coming.

"I didn't know what it was going to be, but I knew we were coming to a special place, I know I got my breakthrough win here, and it's a very special place for my family. The fact my parents were able to come, I got out of COVID protocol early, I just felt like the stars were aligning.

"I can't even believe I made the first two putts! This was definitely for Seve [Ballesteros]. I know he tried a lot, and wanted to win this one most of all. I just don't know how to explain it! I don't know why, but every time we land here, we are happy. We’re in our spot!"

Oosthuizen was initially circumspect on day four, going one over through eight holes to leave the South African one shot behind defending champion Bryson DeChambeau – who came agonisingly close to a sensational hole-in-one at the par-three eighth.

But DeChambeau was unable to maintain his hot start, finishing with a forgettable six-over-par 77 to end the event eight shots off the pace.

Oosthuizen also failed to keep Rahm at bay – dropped shots at the 11th and 17th holes, paving the way for the red-hot Spanish golfer to emerge triumphant for the first time at a major.

Harris English (68) finished solo third, a stroke better off than Guido Migliozzi (68), two-time U.S. Open winner Brooks Koepka (69) and Collin Morikawa (70) as former world number one Rory McIlroy's final-round 73 resulted in a share of seventh spot at one under.

World number one Dustin Johnson (74) and fellow stars Jordan Spieth (72) Justin Thomas (73), Patrick Reed (67) and Sergio Garcia (68) closed out the event tied for 19th.

Louis Oosthuizen opened up a one-shot lead in a gripping final round at the U.S. Open.

Oosthuizen was in a three-way share of the lead heading into Sunday at Torrey Pines but was initially circumspect, going one over through eight.

That put the 2010 Open winner a shot behind defending champion Bryson DeChambeau, who came agonisingly close to a sensational hole-in-one at the par-three eighth.

That birdie result was enough for the outright lead on five under at the turn, although the American's first bogey of the weekend on 11 came as Oosthuizen's putter heated up, picking up shots on nine and 10. Oosthuizen dropped one at 11 though.

DeChambeau erred again, meaning Jon Rahm – who flew out of the blocks with back-to-back birdies – was the nearest challenger to Oosthuizen alongside another overnight leader Mackenzie Hughes on four under.

Rory McIlroy drained a 35-footer on the fourth, leaving him well-placed early on minus four.

However, the Northern Irishman passed up three further birdie opportunities by the midway point of his round and his hopes were fading when he bogeyed the 11th.

That left McIlroy level on three under with Brooks Koepka, although the American four-time major winner was through 16 holes and appeared to have missed his moment to make a decisive move.

The 2020 US PGA champion Collin Morikawa was one of the pack on four under until he went through the green on 13 and left with a double bogey.

Louis Henley was alongside Oosthuizen and Hughes in the clubhouse on Saturday but also dropped back to minus two, albeit in less spectacular fashion than Morikawa.

Bryson DeChambeau is fully embracing the atmosphere created by the so-called 'Brooksy bros' at the U.S. Open.

There is little love lost between defending champion DeChambeau and two-time winner Brooks Koepka, with their simmering rivalry one of the more intriguing sub-plots in golf during 2021.

At last month's US PGA Championship, a video of Koepka visibly frustrated at an interruption from DeChambeau went viral, which led to the pair trading back-and-forth jibes on social media.

Prior to the tournament, DeChambeau admitted the two just "don't like each other". On Sunday, as he contemplated going for the par-five 18th in two while in a sand trap, fans of Koepka yelled "go get 'em Brooksy" and "Brooks would go for it".

DeChambeau resisted the temptation to bite but when questioned about it after his round, the world number five insists he is relishing the rivalry.

"Hey, I love it. I think it's so much fun," said DeChambeau, who recorded his first ever bogey-free round in major golf to sit two back of leaders Mackenzie Hughes, Louis Oosthuizen and Russell Henley at three under at Torrey Pines.

"People think that it annoys me. If anything, it just creates a great atmosphere for golf. At first, I didn't really know how to handle it. You're kind of thrown into a situation. 

"But now I enjoy it. I think it's great. You've got to embrace it. There's going to be team Bryson, team Brooks out there, and hey, keep it up, I'm happy about it. 

"I'm excited that one day we can eventually get paired up and play together. It would be fun."

DeChambeau, who scored a three-under 68 in round three, is using driver at almost every opportunity in tactics similar to those he employed when winning at Winged Foot last year.

He says he has learned the nuances of coping with major golf.

"You've got to be really patient out here at these majors. It's something that is not easy to do," he added.

"My first few goes at majors, I was not successful or anywhere near successful, and I feel like I'm starting to understand major championship golf and how to play it and how to go about managing my game, my attitude and just my patience level. 

"If I can continue to do that [on Sunday], I think I'll have a good chance."

Jon Rahm is three off the lead after signing for a one-over 72 on Saturday. The Spaniard thinks being part of the chasing pack may actually play to his strengths.

"I feel like it's easy when you're in the lead to get a little tentative and start trying to be a little bit more safe in certain parts," he said. 

"I feel like when you're a couple shots back, you have nothing to lose early on. So, I feel like you can be a little bit more aggressive and try to get some birdies.

"There will be somebody who gets a fast start, and hopefully that's me tomorrow, and I get a fast start, and I get it going fast."

Since winning The Open in 2010, Oosthuizen has been a perennial nearly man in the majors, recording five runners-up finishes including play-off defeats at the 2012 Masters and 2015 Open, while he was tied second to Phil Mickelson at the PGA Championship last month.

The South African is aiming to take the positives from those experiences, though, saying: "The two that really hurt was the playoffs. That's so close to winning.

"You know, the other ones, just good weeks and good results. Could have been better but taking more positive out of it than anything else."

Oosthuizen drained an eagle at the par-five 18th, which drew a huge reaction from the galleries.

"A year ago, that would have been a very boring eagle with a few people going nuts. But that was nice to see everyone back," he said, alluding to the return of fans who were unable to attend in 2020 due to the coronavirus pandemic.

Ten years to the day after he wrapped up his first major championship win at Congressional, Rory McIlroy put himself in position for another U.S. Open title by shooting 67 Saturday at Torrey Pines. 

McIlroy is three under par for the tournament, two strokes back of the leading trio of Louis Oosthuizen, Mackenzie Hughes and Russell Henley entering Sunday's final round. 

The Northern Irishman will feel good about his chances after a round that featured five birdies and just one bogey a day after he shot a wobbly 73. 

The lone bogey may have been the key to his round, a difficult save that kept him from losing momentum after what had been a positive day. 

"This is the only tournament in the world where you fist pump a bogey," McIlroy told reporters.

"Only losing one there was a big deal, and getting it up-and-down out of the bunker on 16 and making that birdie on 18 just to get that shot back that I lost, really big."

By the end of the day, McIlroy considered it "one of the best rounds of golf I've played in a while." 

The 32-year-old broke an 18-month title drought with his win at the Wells Fargo Championship in May.

He also won that tournament in Charlotte, North Carolina for his first PGA Tour victory six weeks before securing his first major championship a decade ago.

There will be no repeat of that astonishing eight-stroke victory over Jason Day this weekend, but McIlroy is satisfied to be in the hunt for his first major title since the 2014 US PGA Championship. 

"I mean, I'm trying to think of the last time where I really felt like I had a chance [at a major]," he said.

"Carnoustie in '18 felt like I maybe had half a chance, going into the final day at Pebble in 2019.

"But apart from that, there's been some good finishes but never felt like I was in the thick of things.

"I'm just excited for the opportunity to have a chance and be in one of the final groups."

Louis Oosthuizen and Mackenzie Hughes used eagles on the back nine to surge into a share of the lead heading into the final round of the U.S. Open. 

They join Russell Henley atop a crowded leaderboard at Torrey Pines after the second-round co-leader saved par on 18 to complete an up-and-down round and sit at five under par for the tournament. 

Oosthuizen finished with a flourish, draining a downhill putt for eagle on 18 to cap his one-under 70 as he continues the quest for his second major title 11 years after winning the Open Championship. 

The unheralded Hughes, meanwhile, eagled the 13th and birdied the last for a 68 on the day. He is the first Canadian to hold at least a share of the lead after 54 holes of a major since Mike Weir at the 1999 US PGA Championship. 

The 30-year-old missed the cut in his last five PGA Tour starts and has only one career victory, in the 2016 RSM Classic at Sea Island. 

Impressive as Hughes was, the round of the day belonged to Rory McIlroy (67), who also birdied the 18th to reach three under for the tournament exactly 11 years after he closed out his runaway U.S. Open win at Congressional. 

Bryson DeChambeau (68) also lurks two back of the leaders after a bogey-free third round. 

Jon Rahm (72) is among the group at two under as he seeks his first major title, along with 2020 U.S. Open runner-up Matthew Wolff (73) and Scottie Scheffler (70).

The 2016 U.S. Open champion Dustin Johnson (68) is four back of the lead at one under along with 2020 US PGA champion Collin Morikawa (70), Christiaan Bezuidenhout (70), Xander Schauffele (72) and Kevin Streelman (72). 

Among other notables, Brooks Koepka and Justin Thomas are at even par after shooting 71 Saturday, while Jordan Spieth (68), Martin Kaymer (69), Lee Westwood (71) sit one over. 

Richard Bland, who shared the lead with Henley after the second round, plummeted down the leaderboard to one over with a brutal round of 77 punctuated by the 48-year-old putting his approach shot in the water on 18. 

Rory McIlroy and Dustin Johnson kept themselves well within a shout of second respective US Open successes with excellent third rounds on Saturday.

Johnson put in his best performance of this year's event at Torrey Pines, carding a 68 which moved the world number one to one under par, and he would surely have been even closer to the leaders if not for a dismal loss of form on the back nine on Friday.

"I feel like I'm swinging really well. I didn't drive it on the fairway enough but I felt like I managed the game pretty well. I rolled the putter really nicely today and made a lot of clutch par putts, which is what you've got to do in the US Open," Johnson told Sky Sports.

"When I was on the fairway I felt like I played pretty well, my irons were good and I'm controlling my distance – I'm just not getting enough shots from the fairway.

"I felt like they did a really good job of setting the course up - if you drive it on the fairway, you can attack the golf course and it's been like that all week. There's a few holes obviously where you will take a four and run but for the most part the way they set it up today, you can attack it."

McIlroy, meanwhile, went one better, finishing on 67 for the round to keep his chances firmly alive. The 2011 champion's birdie on the 18th ensured he was the clubhouse leader at three under.

Russell Henley, meanwhile, reached the turn with a two-shot lead over Richard Bland.

The overnight leader reached the front of the ninth in two shots, yet missed his eagle attempt and subsequently had to settle for a three-out par, whereas Henley snatched a birdie.

However, Henley then dropped a shot on the 10th, immediately cancelling out his own advantage.

Bryson DeChambeau is also in the hunt, with the defending champion T3 with McIlroy, Jon Rahm and Matthew Wolff.

Paul Casey had looked sharp earlier in the day, yet bogeys on the 16th and 17th meant he had to settle for 67, and heads into round four on par.

Bryson DeChambeau said his swing fix "came to him" in a dream after the U.S. Open champion kept his title defence alive.

DeChambeau opened his bid for back-to-back U.S. Open trophies with a 73 but the big-hitting American responded by posting a two-under-par 69 on Friday.

An eagle, four birdies and four bogeys saw DeChambeau surge 47 positions on day two, moving within five shots of co-leaders Richard Bland and Russell Henley at Torrey Pines.

Reflecting on his bounce-back display heading into the weekend, DeChambeau credited a late-night tweak.

"I was sleeping and it came to me in the middle of the night," DeChambeau told reporters.

"Woke up and I was like, hmm, I'm going to try this, and my intuition is pretty good, so I went out and tried it and it worked, just keeping the right wrist bent for a lot longer through impact."

"It's more just my intuition telling me there's something weird here, what's going on, and I couldn't figure it out for an hour and a half last night, an hour last night," said DeChambeau said. "Going back and just sitting down, eating dinner and just thinking about it, thinking about it, I literally won't talk to anybody for like an hour, just thinking, thinking, thinking, and sure enough, I went to bed and I found a little something that worked for my driver."

DeChambeau added: "I feel like if I can clean up my iron play and get a little more comfortable with the irons and the drivers, I'll have a good chance for this weekend."

He is tied for 13th alongside the likes of rival Brooks Koepka (73), Justin Thomas (69) and Collin Morikawa (67).

Amid their ongoing feud, DeChambeau and two-time U.S. Open champion Koepka narrowly avoided being paired together for Saturday's penultimate round.

Koepka – eyeing a fifth major crown – lost ground on the leaders after mixing five bogeys and just three birdies but he told reporters: "I feel right there. I feel like I'm in it. Just need to put two solid good rounds and put the ball in the fairway, and that's it. I love the way I'm putting. I love the way I'm striking it. Just need to keep doing it."

Four-time major winner and former world number one Rory McIlroy is a stroke further back following his second-round 73.

"A bit of a rollercoaster, got off to a good start," McIlroy said. "Made a couple of birdies early on and was under par for the round. Then I made a couple of mental errors and missed it in the wrong spots, and when you do that around this golf course, it's just really hard to see a par.

"I made a few bogeys, but birdieing two of the last four holes definitely makes me feel better about the round and gives me a nice bit of momentum going into tomorrow…So, yeah, in for the weekend and still feel like I've got a really good chance."

US PGA Championship winner Phil Mickelson also feels he can "make a run at it" after avoiding the cut on Friday.

Richard Bland upstaged a star-studded field to earn a share of the U.S. Open lead at the halfway stage as defending champion Bryson DeChambeau soared up the leaderboard.

Unheralded Englishman Bland, 48, powered to the top of the summit at Torrey Pines thanks to his four-under-par 67 in San Diego, where he continues to prove patience pays off.

Alongside Russell Henley (70) for the one-stroke lead after two rounds, Bland is benefitting from perseverance, having gone almost 20 years without a European Tour title.

At the 478th attempt on the European Tour last month, Bland claimed an emotional win at the British Masters, which earned him a place in his fourth major championship.

Bland – who missed the cut at his one previous U.S. Open appearance in 2009 – dazzled on day two of this year's tournament, storming into the clubhouse lead before being joined by American Henley.

After opening with a 70, Bland holed seven birdies and three bogeys to catapult himself to the top of the standings, before Henley teed off in his second round, amid his improbable dream of clinching a major.

"I feel good about my game," said three-time PGA Tour champion Henley, whose previous best performance at a major came via an 11th-place finish at the 2017 Masters.

"I've never been in this position before in a major. Just feel like I'm going to learn something no matter what happens."

Louis Oosthuizen (71), who was the overnight co-leader along with Henley, ended day two in a tie for third position alongside Matthew Wolff (68), while Bubba Watson (67) and Jon Rahm (70) are a shot further back at three under through 36 holes.

DeChambeau boosted his hopes of back-to-back U.S. Open titles, though the big-hitting American star remains five strokes off the pace heading into the weekend.

A two-under-par 69 saw DeChambeau move to even par as he rose 47 positions into a tie for 13th alongside rival and two-time U.S. Open champion Brooks Koepka (73), Justin Thomas (69), Collin Morikawa (67), Harris English (70), Branden Grace (70), Christiaan Bezuidenhout (70) and Adam Hadwin (72).

Koepka – eyeing a fifth major crown – lost ground on the leaders after mixing five bogeys and just three birdies, while Rory McIlroy followed his opening-round 70 with a 73 to be one over the card as world number one Dustin Johnson (73) ended the day two over.

US PGA Championship winner Phil Mickelson emerged from the jaws of elimination, qualifying for the weekend via a two-under-par 69 after his forgettable 75 on Thursday.

Masters champion Hideki Matsuyama (76), Adam Scott (75), Sergio Garcia (74), Patrick Reed (73) and Jordan Spieth (69) all avoided the cut, but Justin Rose (77) was not so fortunate at 13 over.

Bubba Watson believes golf should be celebrating the biggest hitters in the game – and he cannot work out why the sport is so "mad at that guy".

Without naming Bryson DeChambeau, Watson appeared to have his mind set on the likes of the man who leads the PGA Tour for driving distance this season.

DeChambeau, who is driving an average of over 320 yards, has faced some flak for placing such an emphasis on physical strength and building up his body to be more powerful off the tee. He plays with custom clubs, each of the same length, and is the defending champion this week at the U.S. Open, an unorthodox winner who rubs some up the wrong way.

Two-time Masters champion Watson, after moving into contention following the second round at Torrey Pines, used his platform to condemn what he sees as a culture of negativity towards players re-thinking the game and finding new ways to win.

"Truthfully, here's the sad part for me. I've got the microphone so I'm going to talk. The sad part for me is we celebrate every sport in the world. We celebrate accomplishments. We celebrate a guy scoring 50 points in the NBA. They are not saying quit shooting three-pointers. But we don't celebrate when a guy makes eight birdies or a guy bombs it 400 yards," Watson said.

"I don't understand how we're not celebrating. We're trying to make golf courses bigger, harder, dumber, however you want to word it, but we're not celebrating our great players.

"I'm definitely not in that group of great players. I'm saying I want to see these guys hammering the ball. I want the next up-and-comer. I want a 6ft 8in guy not playing in the NBA, I want to see him on the PGA Tour bombing the ball.

"We're the only sport not celebrating accomplishments of being a guy working out in the gym that can hit the ball miles. We're mad at that guy. I don't know why, but we are. I'm not, but some people are – golf course designers.

"The NBA, Tom Brady winning, throwing touchdowns, we celebrate that. They don't ever talk about us chopping out of the – hey, he laid up again. That's great. Anyway, that's my rant for the day."

Watson was offloading that baggage after adding a 67 to his opening 72 to reach three under, looking sure to be in contention going into the weekend as he sits just two shots behind clubhouse leader Richard Bland.

DeChambeau followed a 73 with a 69 to sit on level par, still in the hunt at five off the pace.

That was a far healthier position than Patrick Reed, Justin Rose and Jordan Spieth found themselves in.

Reed bogeyed his final hole to slip to three over, a five-foot putt brushing the edge of the cup. Reed won the Farmers Insurance Open at Torrey Pines earlier this year but was on the borderline of the cut mark after his round on Friday.

Rose added a 77 to his opening 78, and that meant the former champion had no chance of staying around for the weekend's action.

Three-time major winner Spieth followed an opening 77 with a gutsy 69 to give himself a slim chance of making the cut.

Richard Bland, the Englishman who was a first-time winner at the 478th attempt on the European Tour last month, shot to the top of the U.S. Open leaderboard on Friday.

The 48-year-old enjoyed an emotional victory at the British Masters, held at The Belfry, and that helped to earn him a place in his fourth major championship.

He missed the cut on his one previous U.S. Open appearance, in 2009, but this time at Torrey Pines there was no danger of that, with Bland storming into the clubhouse lead and expressing the hope he might remain in the hunt come the back nine on Sunday.

Bland followed an opening 70 with a 67 to reach five under par, and that put him one ahead of Russell Henley, who was yet to start his second round, with Francesco Molinari and Rafa Cabrera Bello tied for third on three under. They too had yet to get under way. Louis Oosthuizen was also at three under through 14 holes, one over for his day.

Starting on the back nine, Bland began his second round with a birdie at the long par-four 10th and picked up three more shots by the turn, although he also gave two back.

Further gains at two, four and six moved Bland to six under, two clear of the field, but a dropped shot at eight meant his lead was trimmed.

When asked how he was feeling about his effort, Bland said: "Pretty good. Whenever you're leading in a major after 36 holes, you've got to be happy, especially at the U.S. Open. To be five under, I'm over the moon."

Speaking on the Golf Channel, Bland said fellow Englishmen Lee Westwood and Justin Rose, both former world number one players, had been among those who had given him pointers before the tournament began. 

"I got some good information off Lee Westwood on Monday and Rosey on Wednesday. My coach Tim Barter, as well, gave me some notes. But I've been driving the ball well for a while now and that's critical at a U.S. Open, especially for someone like myself. I'm not one of the longer hitters. To hit fairways is more of a premium on a course this long.

"When I saw the course, it's set up pretty straight, it's all there in front of you, so if I kept driving it well I felt I could give myself chances."

Bland, who battled back from losing his European Tour card in 2018, admitted it would be impossible for him not to think about the prospect of landing a major.

"Of course, it's going to be pretty tough not to do that, but you look at the leaderboard and see the guys behind, and there's guys who have got a lot more on their CV than I have," Bland said.

"But I'm going to try to enjoy it, best I can. I'm here to compete and give it the best I've got and hopefully come the back nine on Sunday I'm there or thereabouts.

"That's all you can do, there's still 36 holes to go. Every hole is a potential disaster around here, but if I can keep doing what I'm doing I think I can be in there come Sunday."

He would not become the oldest major winner, of course, should Bland follow his efforts on the opening two days with a title push over the weekend.

Phil Mickelson owns that record, having won the US PGA Championship last month at the age of 50.

At his home course in San Diego this week, Mickelson began his U.S. Open effort with a four-over-par 75, meaning his prospects of adding this title to his collection to complete a career grand slam looked slim as he prepared to set out for his round on Friday. He was likely to need to shoot one or two under par to make the cut.
