Kim Si-woo secured the fourth PGA Tour win of his career after producing a remarkable finish at the Sony Open in Hawaii.

After beginning the week with back-to-back rounds of 67, Kim posted consecutive 64s on the weekend to finish at 18 under.

He trailed by one as he reached the 17th hole, and despite missing the green on the par-three, he pulled things even at 17 under with a chip-in. He then reached the green on the par-five final hole in two shots, two-putting for another birdie to take the outright lead.

Kim finished a few holes before Hayden Buckley in the final group, leaving Buckley with a chance to force a playoff if he could birdie either of the 17th or 18th, but he could only muster a pair of pars.

Buckley may have had the edge if he could have taken it to a playoff, with Kim winless in his three playoffs on the PGA Tour, but he finished at 17 under in outright second.

For Kim, the victory is just his second in the six years since bursting onto the scene when he won The Players Championship in 2017, with his only other title since then coming in January 2021 at The American Express.

Chris Kirk finished alone in third at 15 under, while England's Ben Taylor tied for fourth at 14 under with American duo Andrew Putnam and David Lipsky.

Hayden Buckley finished the third day at the Sony Open in Hawaii with an eagle to claim a two-stroke lead from David Lipsky, Ben Taylor and Chris Kirk on Saturday.

Buckley carded a six-under-par round of 64 to be 15-under overall, managing two eagles on the third day along with three birdies and a bogey at Waialae Country Club.

The American sunk a 28-foot birdie putt on the eighth hole, before he moved into the lead buoyed by an excellent back nine where he nailed a 133-yard hole-out eagle on the 10th hole along with another on the 18th aided by a pinpoint approach.

Halfway leader Kirk slipped after a third-day 68 which started with a double bogey on the first hole, although he expertly produced a hole-out birdie from the bunker on the 14th to stay in contention.

Lipsky had an up-and-down round that included seven birdies and three bogeys, while Englishman Taylor birdied four of his final six holes to be tied for second at 13 under.

Andrew Putnam shared the round of the day with Nick Taylor, both carding eight-under-par rounds of 62, with the former moving to 12-under overall.

Putnam, who managed a career-high 10 birdies, is tied with Si Woo Kim, who had a strong third round with seven birdies in his 64.

Will Gordon and Nate Lashley are a further shot back at 11 under, while J.J. Spaun's third-round 71 saw him drop to well off the pace and nine under.

Two-time major winner Hideki Matsuyama enjoyed his best round at the Sony Open with a 65, leaving him at eight-under overall.

Chris Kirk is alone atop the leaderboard at 11 under following Friday's second round of the Sony Open in Hawaii.

Kirk was in a three-way tie for the lead after shooting a six-under 64 on Thursday, and he followed it up with a 65 in his second trip around Waialae Country Club.

He began his round in blistering fashion, collecting birdies on each of the first three holes to put himself in a commanding position, and he finished with a birdie on the 18th.

J.J. Spaun looked a sure thing to finish the day tied with Kirk at 11 under as he reached his final hole – the par-five ninth – with a share of the lead.

Despite it playing as the easiest hole on the course, Spaun found the water, resulting in his first bogey of the week to head into the weekend at 10 under.

Spaun is tied for second with American compatriot Taylor Montgomery, while Hayden Buckley and David Lipsky are at nine under to round out the top-five.

England's Ben Taylor is part of the three-man group at eight under, Germany's Stephan Jaeger is at seven under, Kim Si-woo is at six under and former Masters champion Adam Scott headlines the group at five under.

Hideki Matsuyama finished the day two strokes inside the cut-line at three under, while joint first-round leader Jordan Spieth imploded for a five-over 75 to miss the cut at one under.

Jordan Spieth owns a share of the lead after the first round of the Sony Open in Hawaii, tied with Chris Kirk and Taylor Montgomery at six under.

A three-time major champion, Spieth has one PGA Tour win in each of the past two seasons, and this week he is seeking his first top-10 finish since The Open in July.

He posted seven birdies and one bogey during his first trip around the picturesque Waialae Country Club course to shoot 64, while Kirk and Montgomery reached their scores in identical fashion, joining Spieth at the top after both birdieing their final hole.

Kirk has not won a PGA Tour event since the Crowne Plaza Invitational at Colonial in 2015, but he flashed some form this past season with four top-10 finishes, including a tie for fifth at May's PGA Championship. Montgomery entered the season with no career top-10s, but has three in his seven starts this campaign.

There is a seven-way tie for fourth place at five under featuring Slovakia's Rory Sabbatini from the early group and South Korea's Seong-hyeon Kim from the late finishers.

The densely packed field means there is a further logjam at four under including Maverick McNealy and top-five finisher from last week's Sentry Tournament of Champions, J.J. Spaun.

England's Aaron Rai is at three under, Japanese major champion Hideki Matsuyama is at two under and fellow former Masters champion Adam Scott of Australia is at one under.

The highlight of the day came from Ryan Armour, who finished his round at even par, but enjoyed a moment he will never forget after hitting his second ace of the season on the par-three 17th.

Hideki Matsuyama produced a stunning second shot on the first playoff hole to claim victory at the Sony Open in Hawaii as he triumphed over Russell Henley.

The reigning Masters champion had trailed by five strokes on the back nine but produced a surge capped with a birdie at the last to force a playoff with Henley after both finished 23 under par.

Henley's putt on the 18th to win the tournament skimmed the outside edge of the hole and he was left to rue that miss in quite astonishing fashion.

They returned to the same hole for the playoff and Matsuyama, having gone for the 3-wood off the tee, elected to use the same club for his second shot from 277 yards away and could not have hit it any better, sending it to three feet for an eagle putt to secure his eighth PGA Tour title and his third in less than a year as Henley made bogey.

Waialae Country Club holds a special place in Japanese golf history, with it being the course where Isao Aoki became the first player from the country to win on the PGA Tour.

And Matsuyama was thrilled to replicate his achievement.

"I got on a roll, I'm glad it came out this way," said Matsuyama. "To follow him [Aoki] up, I'm over the moon."

Kevin Kisner and Seamus Power were Matsuyama and Henley's closest challengers, finishing in a tie for third, four strokes off the pace.

Russell Henley remains in the lead ahead of the final day of the Sony Open in Hawaii but 2021 Masters Championship winner Hideki Matsuyama surged into contention on Saturday.

Henley carded a three-under-round of 67 to maintain his lead after being three strokes ahead at the halfway mark at the Waialae Country Club.

Japanese 29-year-old Matsuyama, though, moved up the leaderboard into second spot, two shots behind Henley, with a seven-under-63 to be 16 under overall.

Henley leads at 18 under, with Matsuyama 16 under, before four players are tied at 14 under in third in Adam Svensson, Seamus Power, Matt Kuchar and Haotong Li.

The American, who won the Sony Open in 2013, had two bogeys and five birdies in his round, including a 16-foot birdie putt on the 17th hole to buffer his lead after Matsuyama made his move earlier in the day.

Matsuyama, who carded rounds of 66 and 65 on the first two days, improved with a day-three 63 headlined by four birdies in his final seven holes.

Svensson and Power both hit five-under-rounds of 65 to remain in contention, while Kuchar and Li are close but carded rounds of three-under and two-under to fail to close on Henley.

American Russell Henley holds a three-stroke lead at the halfway mark of the Sony Open in Hawaii after a seven-under-63 on Friday.

Henley, who won the Sony Open in 2013, carded an eight-under-62 on the opening day and backed that up to be 15-under and three shots ahead of second-placed Haotong Li.

Li along with third-placed Matt Kuchar and equal fourth Chris Kirk all carded rounds of five-under-65.

Kirk is one of 10 players tied for fourth alongside Seamus Power, Stewart Cink, Corey Conners, Adam Svensson, Keita Nakajima, Davis Riley, Dylan Wu, Brandt Snedeker, Payton Kizzire and 2021 Masters winner Hideki Matsuyama.

Henley's seven-under-63 was a round-best alongside Cink and Charles Howell III who both surged up the leaderboard.

The 32-year-old American had an even card on the second round before holing a bunker shot for eagle on the 18th hole, his ninth hole of the day.

Henley came home strong with four birdies and an eagle in his final six holes, including a 29-foot eagle putt. He has three PGA Tour titles across his career, the last being in 2017.

Veteran Jim Furyk dropped well off the pace after his fast start, with a two-over-round of 72 leaving him six under at halfway, while day one leader Kevin Na slipped to eight under after a round of one-over-71.

Jim Furyk rolled back the years with a hole-in-one at the Sony Open to finish the opening round in Hawaii one shot behind leader and defending champion Kevin Na.

The 51-year-old, who has 17 PGA Tour victories to his name, sunk the perfect shot on the par-three 17th on his way to finishing eight under on Thursday.

Furyk was hampered by a slow start at Wai'alae Country Club with a bogey on the opening hole, though that proved to be the American's only dropped shot in a round of 62.

That makes Furyk the oldest player to shoot 62 or better on the PGA Tour since 1983 as he looks to win the tournament for a second time, 26 years on from his previous triumph.

"I'm trying to get ready for this year. I want to be competitive this week," said Furyk, who made the sixth hole-in-one of his career and first since 2011.

"I want to compete and put myself in position, in the hunt, and also want to get a feel for where my game is and what I want to work on for the year."

Furyk will resume day two level with compatriot Russell Henley and a stroke behind blemish-free Na, who is aiming to defend the crown he won last year.

Na was on course for a sub-60 round, but three good birdie chances passed him by and he now has seven challengers within two shots of his lead.

The South Korean settled for 61 to tie his career-low round on the PGA Tour. He leads the way for the most rounds-of-62 or better since such data was first recorded in 1983 (10).

Na, Furyk and Henley are three of six past Sony Open winners in the top 10 after day one, along with Matt Kuchar, Patton Kizzire (both six under) and Ryan Palmer (seven under).

Elsewhere, Cameron Smith could not build on his record-breaking win at last week's Sentry Tournament of Champions as a couple of bogeys left him three-under par in a tie for 40th.

Kevin Na birdied the final hole to win the Sony Open in Hawaii by one stroke on Sunday.

The American carded a five-under 65 in the final round at Waialae Country Club, finishing a stroke clear of Chris Kirk (65) and Joaquin Niemann (66).

Na made a short birdie putt after producing a great chip on the final hole, the birdie sending him to 21 under and victory.

It marked his fifth PGA Tour win and fourth in two and a half years.

"It's a nice feeling. I know it's a Ryder Cup year, it's all positives. I feel great," Na told a news conference after his win.

"It's four seasons in a row I've won, it's a great feeling, nice to get it done early but I'd like to win another one before the season is over."

Behind Kirk and Niemann were Webb Simpson (64), Marc Leishman (65) and overnight leader Brendan Steele (69).

Niemann, who lost a play-off at the Tournament of Champions last week, finished second for the second straight week.

The last player to finish second in back-to-back weeks on the PGA Tour was Simpson in 2019.

Patton Kizzire (64), Collin Morikawa (64), Billy Horschel (65) and Daniel Berger (66) finished tied for seventh at 18 under.

Brendan Steele recorded the lowest round of his PGA Tour career as he claimed a two-stroke lead after the third round at the Sony Open in Hawaii.

American golfer Steele – who lost a play-off at last year's tournament – posted a nine-under-par 61 to rise six positions to the top of the leaderboard in Honolulu on Saturday.

A three-time Tour champion, Steele was flawless at Waialae Country Club, where he drained nine birdies, including his final two holes to be 18 under overall.

Steele holds the outright 54-hole lead for the second consecutive season at the Sony Open in Hawaii. He could become the first player to lose a play-off and win the same event the following season since Ryuji Imada in 2008.

Kevin Na (61) and Joaquin Niemann are Steele's nearest challengers heading into the final round of the tournament.

Na equalled his career low-round, while the American is now tied with Brandt Snedeker and Justin Thomas for the most rounds (four) of 61 or better on Tour since 2014.

Peter Malnati (64), Charley Hoffman (64), Russell Henley (65), Chris Kirk (65) and Stewart Cink (65) are three shots off the pace.

Overnight leader and Canadian Nick Taylor, meanwhile, dropped down the leaderboard following his two-under-par 68.

Taylor ended the round tied for ninth on 14 under, alongside Marc Leishman (65), Keith Mitchell (63) and Daniel Berger (64).

Nick Taylor climbed into a two-stroke lead at the halfway mark of the Sony Open in Hawaii after carding an eight-under 62 on Friday.

The Canadian kick-started his second round with an eagle at the 18th hole – his ninth – before getting to 12 under at Waialae Country Club.

Taylor was one under through eight holes in his round before chipping in for the eagle, and he picked up another five shots on the back nine.

A two-time winner on the PGA Tour, Taylor is two shots clear of Stewart Cink (63), Webb Simpson (65), Russell Henley (64), Vaughn Taylor (66) and Chris Kirk (65).

Henley is a former champion of the event, lifting the trophy in 2013, while Kirk was runner-up a year later.

On what is a congested leaderboard, another eight players are just a shot further back.

Joaquin Niemann (69) and Peter Malnati (69), who shared the overnight lead with Jason Kokrak (71), are among them, alongside Charley Hoffman (65), Collin Morikawa (65), Marc Leishman (65), Hideki Matsuyama (65), Billy Horschel (66) and Brendan Steele (66).

Steele was runner-up last year and is again well-placed to contend after posting rounds of 65 and 66.

Horschel, meanwhile, is the only player in the field bogey-free through 36 holes. It is the third time in his PGA Tour career he has been bogey-free through two rounds.

Defending champion Cameron Smith carded a four-under 66 to sit at seven under – in a tie for 19th in a group that includes Kokrak.

Joaquin Niemann is part of a three-way tie for the lead after the opening round of the Sony Open in Hawaii.

The Chilean carded an eight-under 62 at the Waialae Country Club on Thursday to lead alongside Peter Malnati and Jason Kokrak.

Coming off a play-off loss to Harris English at the Tournament of Champions, Niemann's fine start to 2021 continued.

The 22-year-old made seven birdies, a bogey and an eagle, the latter coming with a chip in at the 18th.

Kokrak produced a bogey-free opening round, while Malnati mixed nine birdies with one bogey.

At the 17th, Kokrak almost produced a hole-in-one, only to see his shot lip out as he was forced to settle for a birdie.

Vaughn Taylor, Jim Herman, Aaron Baddeley, Patton Kizzire, Daniel Berger and Kim Si-woo are two shots adrift of the leaders.

The champion in 2018, Kizzire made a 45-foot eagle putt from off the green at the ninth, while Baddeley – runner-up in 2003 – is also in contention.

A group of 13 players are at five under, including last year's runner-up Brendan Steele, 2014 runner-up Chris Kirk and 2012 U.S. Open champion Webb Simpson.

Defending champion Cameron Smith opened with a three-under 67 to be in a tie for 40th.
