Eugenio Lopez-Chacarra claimed the LIV Golf Bangkok title after carding a final-round 69 to win by three strokes on a weather-affected final day.

The 22-year-old took a five-shot lead into the final round and did enough to hold off late charges from the likes of Patrick Reed and Paul Casey, the latter of whom will be left to rue an opening round of 71 after shooting 65 on both the second and third days.

Nobody bettered Lopez-Chacarra's first and second rounds of 65 and 63 respectively, and he overcame two bogies on the front nine to finish three under on the final day and seal victory, maintaining his focus despite play being suspended for an hour and a half because of a storm in the area.

The Spaniard was a high-ranked amateur before joining the controversial Saudi-backed tour in June and now earns his first professional championship, as well as a $4million purse.

Richard Bland and Branden Grace formed part of a leading trio with Lopez-Chacarra on seven under after the opening round, but Grace withdrew with injury on Saturday while Bland could not follow up his first-day success, losing pace on the eventual winner to finish joint-third – alongside Casey and Sihwan Kim and a stroke behind second-placed Reed.

Four-time major champion Brooks Koepka was joint-eighth at 13 under, while Bryson DeChambeau ended 14th at 10 under.

Other big names were way off the pace, with Phil Mickelson 10 shots behind Lopez-Chacarra and 2022 Open Championship winner Cameron Smith finishing a disappointing tournament tied for 41st at four under.

Eugenio Lopez-Chacarra will take a five-stroke lead into the final round at LIV Golf Bangkok after ending a brilliant second day in Thailand at 16 under par.

Lopez-Chacarra was one of a leading trio on seven under after the first round, but Richard Bland was unable to keep up with the Spaniard and Branden Grace withdrew after just three holes on Saturday due to an acute muscle strain.

Bland is one of four five shots off the lead with Sihwan Kim, Patrick Reed and Harold Varner III – while they may not be completely out of the running yet, the chasing pack need Lopez-Chacarra to lose momentum.

If his form from the first two rounds is anything to go by, there is little hope of such a collapse, with no one in the field bettering his respective scores of 65 and 63.

Saturday's 63 was nine under par as the 22-year-old – who was a high-ranked amateur before joining LIV Golf in June – carded seven birdies and an eagle, which was holed from the sand on six, and avoided a single bogey.

Those trailing Lopez-Chacarra will be hoping the Madrid native's inexperience leads to a blip on Sunday.

Four-time major winner Brooks Koepka is one of those who will aim to propel himself into contention as he sits on 10 under for the tournament, though victory will require something special.

Few other big names retain much of a chance of glory, however, with Bryson DeChambeau at seven under and Phil Mickelson another shot back.

Sergio Garcia and Dustin Johnson are among a group on four under, while 2022 Open Championship winner Cameron Smith is way down near the bottom of the standings at two under.

If Lopez-Chacarra can hold his nerve on Sunday, he will have gone from amateur golfer to winner of a $4million purse within four months.

Cameron Smith was among the early stragglers at LIV Golf Bangkok as the Open champion finished his first round seven shots adrift of the leaders.

After winning the Chicago leg of the breakaway series last month, Australian Smith would have been hoping for more at Stonehill Golf Course on Friday.

A double bogey at 16 was followed by a pair of pars as he came home in level-par 72.

Eugenio Lopez-Chacarra, Richard Bland and Branden Grace were the unlikely leading trio on seven under, with Marc Leishman and Ian Poulter tied for fourth one shot back.

Brooks Koepka was one of five players on five under, with Phil Mickelson and Bryson DeChambeau three under and Dustin Johnson two under.

Only five players shot worse scores than Smith, with Chase Koepka and Matthew Wolff bringing up the rear on two under.

The three co-leaders all had bogey-free rounds, each posting rounds of 65 after making seven birdies.

Lopez-Chacarra is a 22-year-old Spaniard who was a top amateur before embarking on his professional career in the LIV ranks. He has yet to have a top-20 finish on the tour.

Bland is a 49-year-old Englishman who in May 2021 won his first European Tour title at the 478th attempt; while Grace, with two wins on the PGA Tour and nine on the European Tour, is the renowned top performer among the pace-setting trio.

The Official World Golf Ranking (OWGR) on Thursday revealed that no rankings points will be up for grabs in Bangkok this week or Jeddah next week.

Dustin Johnson got the best of Brooks Koepka in a heavyweight matchup to finish 2 up in their WGC-Dell Technologies Match Play quarter-final.

After Johnson got through Richard Bland and Koepka made it past Jon Rahm earlier on Saturday, the two former major champions went all 18 holes before Johnson won the last to turn 1 up into 2 up and avoid a playoff.

It was a great start for Koepka, winning two of the first three holes, but Johnson found his touch going into the seventh and went on to claim four holes and tie the rest from that point.

Scottie Scheffler passed his test against Seamus Power with flying colours, winning three and two with a strong back-nine.

Winning two holes apiece on the front nine, it was all Scheffler down the stretch, including winning the two par fives (holes 12 and 16) by two strokes to wrap things up with a couple holes to spare.

Brooks Koepka edged a battle of two heavyweights at the WGC-Dell Technologies Match Play, needing a 19th hole to beat world number one Jon Rahm.

The two were paired in the pick of a round of 16 that delivered its fair share of thrills and spills early on Saturday.

Koepka was 2 up twice on the back nine, only to be reeled in by Rahm at the 16th and 17th, meaning an additional hole was required.

A birdie from Koepka was enough as they replayed the 10th, setting up another intriguing quarter-final clash with Dustin Johnson.

For a time, it appeared Johnson would be joining Rahm in making an early exit, as 49-year-old opponent Richard Bland was 2 up through five holes.

However, Bland double-bogeyed the sixth as he lost four of the next five holes, allowing Johnson to canter home 3 and 2.

The other standout match-up saw a replay of last year's final. Billy Horschel won the 2021 title, but he was beaten this time by Scottie Scheffler, who finished 1 up.

Scheffler's next task is against Seamus Power, who this time last year was finishing in a tie for 54th at the Corales Puntacana Resort and Club Championship, leaving him ranked 463rd in the world.

On Saturday, Power routed Tyrrell Hatton 4 and 3 – albeit not the biggest win, as Abraham Ancer dominated Collin Morikawa 7 and 6 and will face Corey Conners, a 5 and 3 winner.

In the final section of the draw, Will Zalatoris required 22 holes to get the better of Kevin Na, with Kevin Kisner up next.

Rory McIlroy wasted a glorious opportunity to win a third Dubai Desert Classic title in a gripping conclusion that saw Viktor Hovland edge Richard Bland in a play-off.

After making steady progress up the leaderboard on Friday and Saturday, McIlroy had a share of the lead alongside Hovland and Bland heading into the final hole on Sunday.

But the four-time major winner, aiming to add to his 2009 and 2015 triumphs in Dubai, sent his approach shot from 267 yards way right on the 18th and it ended in the water.

McIlroy gave himself hope by chipping a shot within 15 feet of the hole to remain on course for par, but his stroke brushed the cup and left him 11-under for the tournament.

That put him a stroke behind Hovland and Bland, who carded a six-under 66 and four-under 68 for the day respectively to finish level and take the competition to an extra hole at the Emirates Golf Club.

Hovland finished strongly with two birdies and an eagle on the final three holes to set the clubhouse lead, which Bland matched with two birdies in a row to conclude his round.

It was Hovland who prevailed in the first play-off hole, the Norwegian rolling in a three-footer for par after Bland's bogey opened the door.

The 24-year-old has now won three of his last five events, having also prevailed at the Hero World Challenge and Mayakoba Golf Classic towards the end of 2021.

Hovland started the day six strokes behind overnight leader Justin Harding, who endured a poor final round, which included a triple-bogey on the 11th to finish in joint-fourth.

"This is pretty wild. I didn't really think this was possible going into today," Hovland said.

"I knew I had to shoot a really low number but a lot of things had to go my way and I am thankful that they did."

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.
