Bryson DeChambeau endured a wild third round, but the FedEx Cup play-off hopeful still ended the day tied for the lead alongside Patrick Cantlay at the BMW Championship.

DeChambeau carded a five-under-par 67 to earn a share of the three-stroke lead through 54 holes at the second FedEx Cup play-off tournament on Saturday.

The 2020 U.S. Open champion's round had a little bit of everything, from back-to-back eagles to back-to-back shots in the water at Caves Valley Golf Club in Maryland.

DeChambeau was flawless on the front nine, mixing two eagles and as many birdies as he turned a one-shot deficit into a three-stroke lead within two holes.

The 27-year-old is the fourth player to make back-to-back eagles this PGA Tour season, while he is only second to Cam Davis (20) for most eagles (19).

Just as DeChambeau threatened to run away from the field, the big-hitting American stumbled, settling for a share of top spot after finding the water at the par-five 12th hole (bogey) and par-three 13th (double bogey).

"It was definitely colourful," DeChambeau – projected to be second in the FedEx Cup points race – told PGA Tour radio. "Thought I played pretty well the front nine, did mis-hit a drive on seven.

"Felt weird. From then on out I wasn't driving it very well, so that's what I'm going to do, work on that for tomorrow. If I can get that straightened out like I did the first few days, off the tee the first couple holes today, I mean, I'll give myself a great chance again."

Cantlay – the current FedEx Cup leader – is also 21 under heading into Sunday's final round following his six-under-par 66.

He was almost bogey-free on day three, holing an eagle and five birdies before bogeying the last.

Im Sung-jae is the nearest challenger after his third-round 66, while Rory McIlroy (65), Abraham Ancer (66), Sam Burns (65) and Sergio Garcia (67) are tied for fourth at 17 under.

World number one and defending champion Jon Rahm lost ground, dropping to outright eighth – five shots back – after a two-under-par 67.

FedEx Cup champion Dustin Johnson posted a seven-under-par 65 to be 14 under, while Brooks Koepka (69) ended the day a further four shots behind – two strokes better off than Justin Thomas (69).

The 121st edition of the U.S. Open takes place at Torrey Pines, a course that previously staged the major in 2008.

Tiger Woods famously triumphed in a dramatic play-off against Rocco Mediate 13 years ago, battling through the pain of a knee injury to secure the trophy for a third time. It was his 14th major triumph, but few would have predicted he would have to wait a further 11 years to add to his collection.

Woods will not be part of the field this week, but reigning champion Bryson DeChambeau will hope to match the feat of Brooks Koepka – winner in 2017 and 2018 – by defending his title.

Besides those two rivals, who else could be in contention for success in California? Time to get out the crystal ball…

LOVE HIM OR HATE HIM, REED CAN TOP THE BILLING AGAIN – Peter Hanson

A divisive figure he may be (even among his own Ryder Cup team-mates), but there is no doubting Patrick Reed's skills on the course. Moreover, he was a winner at Torrey Pines only five months ago at the Farmers Insurance Open – doing so by a convincing five-shot margin.

Four top-10 finishes have followed since, including at the Masters and his most recent tournament the Memorial. At that latter event, he led the field in scrambling and par-three scoring and Reed is tied-sixth for top-10 finishes on the PGA Tour this season. His scoring average of 70.039 is tied 11th and it would be no surprise to see him in contention for a second major this weekend.

XANDER TO 'SCHAUFFELE' OFF WITH TROPHY – Rob Lancaster

Californian Xander Schauffele should feel right at home at Torrey Pines, a venue where he has not always excelled but did finish in a tie for second at this year’s Farmers Insurance Open back in January. He has not won on the PGA Tour since January 2019, though only a play-off defeat denied him retaining the Sentry Tournament of Champions title the following year.

Crucially, the 27-year-old has a track record of doing well in this major. Since 2017, he has not finished outside the top six, including ending up in a four-way tie for third place at Pebble Beach in 2019 when Gary Woodland triumphed. Indeed, an American has been crowned champion in the past six editions – this year could see Schauffele hit another home run.

RAHM THE MAN FOR THIS MAJOR – Benjamin Spratt

Jon Rahm is a man in form heading into this event. Perhaps. It is slightly difficult to gauge exactly how the Spaniard is shaping up, having just recovered from COVID-19, but he was flying the last time we saw him on a golf course. Rahm led by six shots at the Memorial Tournament when he was remarkably required to withdraw following a positive test result.

The premature end to that event will not have hit Rahm's confidence, though, and the 26-year-old should not be lacking in that department heading to Torrey Pines. His first PGA Tour title came on the South Course at the 2017 Farmers Insurance Open, while he was a runner-up at the same event three years later.

IN-FORM CANTLAY CAN LEAD THE WAY – Jonathan Wright

An outside bet perhaps but one certainly worth considering, Patrick Cantlay shot up to number seven in the world after winning the Memorial Tournament in a play-off with Collin Morikawa this month.

That triumph may have come after Rahm had to withdraw, but Cantlay topped a strong field with his best performance of a season in which he has won two PGA Tour titles, claimed five top-10 finishes and leads the way in the FedEx Cup standings. The combination of good form and playing on the home should give the Californian great confidence.

FINAU WILL FINALLY END HIS WAIT – Russell Greaves

Tony Finau is a perennial contender at the majors and it's high time he finally got his hands on a title.

The omens bode well for the 31-year-old, who has 10 top-10 finishes in majors. Finau claimed was among the top 10 at the Farmers Insurance Open in 2017, 2018 and 2020 before ending as joint runner-up this year. He obviously enjoys this course.

He is carrying solid form into this one, too, having earned seven finishes inside the top 10 on tour this season.

Patrick Cantlay defeated Collin Morikawa in a play-off to win the Memorial Tournament on Sunday.

Cantlay earned his second Memorial title, having also won the tournament in 2019, after Morikawa was unable to match his par putt on the first play-off hole.

A sudden-death shoot-out was needed at Muirfield Village Golf Club after Cantlay and fellow American Morikawa finished 13 under through 72 holes following final-round 71s.

It became a showdown between Cantlay and Morikawa on the final day after runaway leader Jon Rahm was forced to withdraw following a positive coronavirus test.

Defending champion Rahm was six shots clear of Cantlay and Morikawa in the third round before the duo were thrust to the top of the leaderboard.

"It's such a weird situation and so unfortunate because, me included, everyone knows it would be a totally different day today had that [Rahm's withdrawal] not happened," Cantlay said after his fourth PGA Tour triumph.

"There's nothing I can do about it and I just tried to work as hard as I could to reset and really get focused.

"I started off a bit shaky today but I really hit a lot of good shots coming in and it felt the same as when I won a couple of years ago. I felt calm and collected and it worked out."

Scottie Scheffler (70) finished two shots behind Cantlay and Morikawa, while Branden Grace (71) was a stroke further back as Patrick Reed and his three-under-par 69 earned him outright fifth at eight under.

Reigning U.S. Open champion Bryson DeChambeau (71), four-time major winner Rory McIlroy (72) and former world number one Jordan Spieth (73) ended the event in a share of 18th position at one under.

Memorial Tournament runaway leader Jon Rahm has been forced to withdraw from the event after testing positive to COVID-19 on Saturday.

Rahm had carded back-to-back rounds of 64 and 65, including a hole-in-one on Sunday, to lead by six shots at 18-under from Collin Morikawa and Patrick Cantlay at 12-under.

However, the Spanish world number three, who was asymptomatic, was informed by officials immediately following his round in dramatic scenes that he had tested positive and would be required to pull out of the event.

Rahm was seen on the TV broadcast being informed of the news by an official, reacting by stooping in anguish and emotionally putting his hands to his face, before walking off the course shaking his head.

The PGA TOUR put out a statement clarifying that Rahm had been subject to contact-tracing protocols as he had come in close contact with a person who was COVID positive.

The statement said: "Rahm has tested negative every day, but his most recent test – which was performed after the conclusion of his second round (rain delayed) and before the start of his third round – returned positive at approximately 4:20 p.m. ET while Rahm was on the golf course.

"The PGA TOUR’s medical advisor requested a confirmatory test on the original sample, which came back at 6:05 p.m. ET, and was also positive.

"The PGA TOUR’s medical advisor notified Rahm immediately upon completion of his round, and under TOUR protocols, he will be withdrawn from the competition. Rahm is now in isolation, and in accordance with CDC guidelines, he will need to remain in isolation through Tuesday, June 15.

"While this is an incredibly unfortunate situation, throughout 50 events since the PGA TOUR’s Return to Golf, there have been only four positive tests (including Rahm) within competition; Rahm is the first positive, asymptomatic case as part of the TOUR’s routine, contact-tracing protocols."

Rahm had been the equal leader at eight-under on Friday after the second round was suspended due to darkness, alongside Cantlay.

The Spaniard raced away with 11 birdies on Saturday as well as a hole-in-one on the 16th to move into the outright lead as he completed his second round.

Morikawa and Cantlay suddenly find themselves in the lead, with the former having shot a six-under 66 on Saturday with eight birdies.

Cantlay finished with a four-under 68 to sit equal with Morikawa at 12-under, with four birdies in his round including sinking a 22-foot putt on the 18th.

South African Branden Grace and American Scottie Scheffler are both tied for second at nine-under, with Max Homa next best at six-under.

Defending champion Jon Rahm joined Patrick Cantlay at the top of the leaderboard before the second round of the Memorial Tournament was suspended due to darkness.

The opening round was hit by storms at Muirfield Village, where most of the field managed to complete their second rounds on Friday.

Rahm – eyeing back-to-back Memorial titles – was through 13 holes when play was called for the day, the Spanish star level at eight under alongside Cantlay.

Cantlay had posted a five-under-par 67 to surge to the top of the standings in Dublin, Ohio.

The 2019 champion, Cantlay played 33 holes on Friday to be tied for the two-stroke lead through 36 holes, ahead of fellow American Scottie Scheffler (71).

Carlos Ortiz (68), Max Homa (through 14), Xander Schauffele (through 12) and Rickie Fowler (through 11) ended the day three shots off the pace at the PGA Tour event.

Overnight leader Collin Morikawa completed 12 holes but slipped down to a tie for eighth at four under, alongside the likes of Masters champion Hideki Matsuyama.

Former world number one and three-time major champion Jordan Spieth recorded a five-under-par 67 to bounce back from his first-round 76 – the American improving to one under.

Reigning U.S. Open champion Bryson DeChambeau also completed his round – an even-par 72 – to be seven strokes behind Rahm and Cantlay but it was a testing day.

DeChambeau was taunted by fans amid his ongoing feud with fellow star Brooks Koepka, with approximately 10 spectators ejected.

There is no love lost between DeChambeau and Koepka, particularly after footage of the latter emerged during a post-round interview at the US PGA Championship.

In a leaked viral video, four-time major champion Koepka was seen rolling his eyes at DeChambeau and cursed in frustration during the interview.

After Friday's second round, DeChambeau said: "I think it's absolutely flattering what they're doing. They can keep calling me that all day if they want to, I've got no issue with it.

"When you look at it, to most people it's they think it's a distraction, but I grew up learning how to deal with that stuff and I honestly thought it was flattering.''

On Koepka – who is not playing this week – DeChambeau said: "Look, I've got nothing against him. I've got no issues at all. If he wants to play that game, that's great. I'm going to keep trying to play my best game and when it comes down to it, when somebody's that bothered by someone else it is flattering."

Meanwhile, four-time major champion Rory McIlroy shot back-to-back 72s to be even par.

Kim Si-woo claimed his first PGA Tour win in almost four years with a one-stroke victory at The American Express on Sunday.

The South Korean carded an eight-under 64 in the final round at the PGA West Stadium Course to finish at 23 under.

It was enough for Kim to win his first PGA Tour crown since May 2017 and third overall.

Kim's win came despite a spectacular final round from Patrick Cantlay, who fired a stunning 11-under 61.

Cantlay broke the course record on the back of 11 birdies.

Australian Cameron Davis finished outright third after a fine eight-under 64 in the final round.

Tony Finau and Max Homa were tied for the overnight lead with Kim, but they slipped back to finish fourth and tied for 21st respectively.

Abraham Ancer (66), Michael Thompson (66) and Doug Ghim (69) finished at 15 under.
