Jordan Spieth and Max Homa capped off their excellent week's work with singles wins to help the United States secure the Presidents Cup by a final score of 17.5-12.5 at Quail Hollow.

Spieth was the only player to win in all five sessions, banking four victories while paired up with Justin Thomas before defeating Cam Davis 4 and 3 in Sunday's singles matchplay.

Despite the comfortable final score, it was Spieth who had to respond to early adversity after Davis won the first two holes, but after clawing back to even, the American rattled off four consecutive victorious holes on the back nine to pull away.

Thomas had a chance to equal Spieth with five wins for the week, but he ended up going down to Kim Si-woo as the South Korean won the 18th hole to finish 1up.

After Spieth, the only other American to finish the competition unbeaten was Homa, who played in three of the four pairs sessions before edging out Tom Kim for a 1up win in the singles.

Xander Schauffele finished 1up against Corey Conners to clinch overall victory for the US team at a time when five matches were still on the course.

In other results to tilt America's way, Tony Finau beat Taylor Pendrith 3 and 1, Patrick Cantlay had a 3 and 2 success over Adam Scott, and Collin Morikawa also won 3 and 2 against Mito Pereira.

However, it proved a highly competitive singles section of the event as the United States only narrowly edged it with six wins and a halved contest, as Sam Burns and Hideki Matsuyama fought out a stalemate.

The Internationals took five of the 12 matchups. Lee Kyoung-hoon was the most emphatic winner from his team, defeating Billy Horschel 3 and 1, while Sebastian Munoz upset world number one Scottie Scheffler 2 and 1 and Christiaan Bezuidenhout got the better of Kevin Kisner 2 and 1.

Im Sung-jae landed a 1up win versus Cameron Young after taking the lead on the 17th hole.

The United States have won nine consecutive editions of the Presidents Cup since a tie in 2003, with the International team's only triumph coming in 1998.

The Internationals have charged back into contention ahead of the final day of the Presidents Cup but still trail 11-7 at Quail Hollow in North Carolina.

USA had led 8-2 heading into Saturday's action that included four morning foursome matchups followed by four fourball contests, with Australia’s Cam Davis and South Korean Kim Joo-hyung starring for the under-dog International team.

The Internationals won two of the morning's foursome matchups and three of the fourball contests to make up major ground but will need win 8.5 points from the 12 on offer on the final day with singles to determine the winner.

If the International team win, it would be the greatest last day comeback in Presidents Cup history and their first victory since 1998 in Melbourne, the team's sole triumph.

"I'm almost in tears," Internationals captain Trevor Immelman said. "I'm so proud of these guys. We've fought so hard. We've had to be so patient."

"We’ve got a very long way to go. We know how tough the Americans are in singles. But today was a great day for us. This team has been through a lot."

Debutant Kim Joo-hyung had one of the moments of the day, sinking a 10-foot birdie putt at the 18th hole to clinch a 1up victory with Kim Si-woo against the previously unbeaten Xander Schauffele and Patrick Cantlay.

The South Korean emotionally reveled in victory after the putt, having holed a 54-foot eagle putt on the 11th hole. In a seesawing fourball contest, Schauffele also putted in from 37 feet on the 15th.

Davis, paired with compatriot Adam Scott, was crucial with late putts in their 1up fourball victory over Sam Burns and Billy Horschel.

On the par-five 16th, Davis sunk an 11-foot eagle putt to win the hole, before making a 14-foot birdie putt to claim the 17th. Davis backed that up with a nine-foot birdie putt to tie 18 and secure the win.

The unbeaten Jordan Spieth and Justin Thomas defeated Hideki Matsuyama and Taylor Pendrith 4 and 3 for USA's only fourballs win, while Im Sung-jae and Sebastian Munoz never trailed as they got past Tony Finau and Kevin Kisner 3 and 2.

In the morning's foursomes, Lee Kyoung-hoon and Kim Joo-hyung defeated Scottie Scheffler and Sam Burns 2 and 1 and Adam Scott teamed up with Hideki Matsuyama to knock off Cameron Young and Collin Morikawa 3 and 2.

USA got victories as Spieth and Thomas won against Im and Corey Conners 4 and 3 and Finau and Max Homa beating Kim Si-woo and Davis 4 and 3. Spieth and Thomas are the third duo in Presidents Cup history to go undefeated in the first four rounds.

"We're in a good spot," USA captain Davis Love said. "We have a lot of guys hitting it good. They just made more putts than we did.

"We always feel like we're at an advantage in the singles. We've had some great singles days in the past."

Friday was the second day of The Presidents Cup, and the second day in a row the United States team came away with four of the five points on offer to lead 8-2 in the best-of-30 competition.

After foursomes was the format on Thursday, things moved to four-ball for the second trip around Quail Hollow, meaning all four golfers in their matchup play each hole, with only the best score from each duo counting towards their score.

Patrick Cantlay and Xander Schauffele – the reigning champions from the PGA Tour's only team event during the season, the Zurich Classic of New Orleans – showed no signs of slowing down after their blistering 6 and 5 win in the opening round, again delivering the biggest margin of victory for the day.

They defeated the duo of Hideki Matsuyama and Tom Kim 3 and 2, and the International team needed to mount a comeback to even survive that long as the United States were 5up through eight holes.

Kim was responsible for all three winning holes for his duo, with birdies on the 12th, 14th and 15th, while Cantlay and Schauffele evenly split their six triumphant holes with three apiece.

The only other fixture to not go the full 18 was Jordan Spieth and Justin Thomas' 2 and 1 win against Australian duo Cam Davis and Adam Scott.

It was another hot start for the United States, with back-to-back birdies from Thomas and one from Spieth putting them 3up through eight holes, and although Davis and Scott both won a hole each down the back-nine, they were never able to bring the margin to within one.

Things were much more competitive in Max Homa and Billy Horschel's 1up win against Canadians Corey Conners and Taylor Pendrith, as the Americans picked up the lead with one hole to play.

Team United States took a 2up lead into the back-nine, which was quickly erased by Conners with two birdies on the 11th and 13th, leaving things tied until the 17th, where Homa delivered a clutch birdie to secure the win.

There were no wins for the Internationals on Friday, but they collected two half-points as the duos of Mito Pereira and Christiaan Bezuidenhout as well as Im Sung-jae and Sebastian Munoz held on to salvage something from the day.

Im and Munoz had a tough matchup against world number one Scottie Scheffler and Sam Burns, but it was Burns doing most of the heavy lifting for the United States, winning three of his team's four holes.

Munoz won three of the Internationals' four holes, including a par on the 17th as both Americans bogeyed to even things up.

Lastly, Pereira and Bezuidenhout were leading through 13 holes, before Cameron Young tied it and collected another half-point for his duo with Kevin Kisner.

Saturday will see teams contest both foursomes and four-ball rounds, before the competition moves to singles play on Sunday.

The United States got off to a blistering start at the Presidents Cup to open lead 4-1 lead over the International Team on Thursday.

Setting the tone for the United States in the foursomes was the pairing of Patrick Cantlay and Xander Schauffele – who are the reigning champions at the only other team event on the PGA Tour calendar, winning at the Zurich Classic of New Orleans this past season.

Matched up against Adam Scott and Hideki Matsuyama at Quail Hollow Club in Charlotte, the Americans were a well-oiled machine, going 4up through the first seven holes, including a string of three consecutive birdies.

While they were the authors of their own early success, the International duo fell apart on the back nine, with three consecutive bogeys handing the United States three more holes, ending the contest at 6 and 5.

The rest of the matches were far more competitive, with Jordan Spieth and Justin Thomas edging the duo of Corey Conners and Sung-jae Im 2 and 1.

Once again, the Americans got off to a flyer to be 3up through six holes, before the Internationals took two of the next three to tighten things up down the stretch.

The 15th hole decided the contest, after it appeared a poor drive and a mediocre chip that rolled to the fringe of the green would cost the United States, but some poor putting from the Internationals opened the door, with Thomas sinking a difficult one to swing the hole in their favour.

Tom Kim and Lee Kyoung-hoon were the only International team to draw first blood, going 1up on the second hole, but they would finish the front nine trailing by two as Cameron Young and Collin Morikawa responded swiftly.

Back-to-back hole wins on the 11th and 12th for the Internationals tied things up, but again the United States were quick to snatch back the ascendancy on the very next hole, closing things out with a birdie on the 17th for a 2 and 1 triumph.

Max Homa and Tony Finau had to wait until the very last hole to secure their win against Taylor Pendrith and Mito Pereira after the Internationals levelled the contest with five to play.

After four consecutive shared holes, Pendrith's approach on the last found the bunker, and they were not able to salvage a par as the Americans kept it clean with a comfortable two-putt for the 1up win.

The Internationals' only win came from the duo of South Korea's Kim Si-woo and Australia's Cam Davis against world number one Scottie Scheffler and Sam Burns, emerging as 2up victors.

It was a great fightback after the United States led most of the round – 3up after seven holes, and 2up through 14 – as the Internationals won the final four holes to snatch a point.

Friday will see the teams go head-to-head in the four-ball format.

Bryson DeChambeau insists he harbours no regrets following his decision to join the controversial LIV Golf Invitational Series.

The 2020 U.S. Open winner became one of the biggest names to join the lucrative Saudi-backed tour in June, later describing his move as "a business decision".

Despite LIV Golf players becoming the targets of hostility when playing at majors and selected events on other tours in recent weeks, DeChambeau remains content with his choice.

"This is the biggest decision, besides choosing my agent, that I've ever made in my entire life," DeChambeau said, ahead of LIV Golf Chicago. 

"I couldn't be more happy to be over here, I have no buyer's remorse. 

"I have ultimate respect for the PGA Tour and what they've done for my career, as I've said from day one. They've allowed me this opportunity." 

While the PGA Tour has reacted furiously to the founding of the new circuit, DeChambeau said in August he was "not worried" by their blanket ban on LIV Golf players, adding: "I think it will get figured out."

The 29-year-old reiterated that belief this week, saying: "I personally believe that over the course of time they will come to a resolution. There has to be, it's only in the best interests of golf down the road.

"What LIV Golf has provided is something new and unique, different. With that being said, there is going to some disruption and people aren't going to like it. 

"I respect every single person who thinks it isn't good for the game of golf, I understand it. But I hope they are open-minded enough to go, 'you know what? I'll give this a chance'. If you give it a chance, you might just see something pretty cool.

"I'm a golf fan, first and foremost. I'm going to watch golf wherever it's played with some of the best players in the world, whoever it is. I think down the road that'll change. 

"I think that this [LIV Golf] will become something special, even more special than what it is now, and moving forward in the future, I'll still watch other tournaments that I've won and done well at before."

The subject of LIV Golf players appearing at team events such as the Ryder Cup has been fiercely debated since the split, with Rory McIlroy adamant this week none of the circuit's players should be able to feature. 

But DeChambeau, who has helped the United States to two victories at the Ryder Cup (2018 and 2021) and one at the Presidents Cup (2019), believes a ban would only serve to harm the tournaments.

"I personally think that the team events are only hurting themselves by not allowing us to play," he added. "Not allowing us to qualify through some capacity, in some facet."

To measure the scope of the Presidents Cup, a suggestion is to travel back in time – 28 years, to be exact – to when this international team golf tournament was introduced.

It was the brainchild of Tim Finchem, back when he was a deputy for PGA Tour Commissioner Deane Beman. But when Beman handed the reigns over to Finchem early in the summer of 1994, going full throttle on the debut of Presidents Cup consumed him.

The naysayers were lined up, but Finchem was steadfast in his belief that great players from beyond the borders of the United States and Europe deserved to compete on a global stage in an international team match. Should you point to the lopsided results – the Americans are 11-1-1 and have won eight in a row – you would be an egregious point-misser.

The Presidents Cup was about bringing the game a little closer together, because global golf, Finchem insisted, was here to stay. He knew it would be a somewhat awkward fit at first, but he begged for patience and offered a vision that a lot of folk struggled with.

To wit, there would be a day when the world's best players competed in the same tournaments dozens of time per year and American golf fans would know the international stars quite well.

If he were the type to seek the limelight, Finchem could take a bow. But instead, let's take a measurement to indicate how his vision has played out beautifully.

In 1994, half the International Team needed to introduce themselves to their American counterparts at the Robert Trent Jones Club in Gainesville, Virginia. Aussie Bradley Hughes had only played in six PGA Tour tournaments that season, while Mark McNulty of Zimbabwe (five), Peter Senior of Australia (three) and Frank Nobilo of New Zealand (two) attended even fewer. As for Robert Allenby of Australia and Tsukasa Watanabe of Japan, they hadn't played at all.

In all, the 12 International Team members had combined for just 141 PGA Tour tournaments in 1994, which is not an indictment of them whatsoever. It is a reminder of the era, when global traffic was limited to the world's very elite names and, while the Presidents Cup perhaps appealed back then to those who are intrigued by players they know little about, Finchem was convinced the stature of the competition would grow as American fans became educated about the Aussies and South Africans, the South Americans and the Canadians.

"In 20 years," he told reporters back then, "we can have an event of really premier quality."

Critique Finchem's statement as much as you'd like, there is an argument to be made that he's been proven correct. Three of the past five competitions have been close (16-14 in Australia in 2019; a one-point match in South Korea in 2015; a closer-than-it-looks 18.5-15.5 decision at Muirfield Village in 2013), and then there is the familiarity aspect: whereas 28 years ago the 12-man International Team combined for just 141 PGA Tour starts, in 2021-22 the 12 members of this year's Presidents Cup team totalled 282 starts.

That is a growth of 100 per cent, and the difference can be seen up and down the line-up. Eleven of the 12 members of this year's International Team made 20-plus Tour starts this year – Tom Kim appeared in 11 events as he eventually earned his card by the end of the season – while seven of them made 25 starts or more.

Budding stars from Chile (Mito Pereira, 27 starts) and South Korea (Lee Kyoung-hoon, 28) head the list of workhorses. Lee's fellow countryman, Kim Si-woo, will join him in Charlotte for his second Presidents Cup after a team-leading 29 starts this season.

Corey Conners made his first team after a year of admirable consistency, as did fellow Canadian Taylor Pendirth (21 starts). Aussie Cam Davis (25), South African Christiaan Bezuidenhout (24), Colombian Sebastian Munoz (25) and Japanese Hideki Matsuyama (21) also help comprise the roster.

Round out the team with South Korean Im Sung-jae, who with 'only' 26 starts this season is almost slacking off, and you have an International Team that is getting more and more comfortable in the US by the week. That, in turn, is why optimism continues to be an International strong suit.

"We're still talking about 18 holes of match play, and we've got to remember anything can happen in an 18-hole match," Adam Scott told reporters at the Rocket Mortgage Classic in late July.

"Momentum plays a big deal in these things. We saw that at the last one. We kind of got up early and we nearly hung on [to win]."

Veteran that he is, Scott would tell you that even as he and his mates have become more comfortable in the US thanks to a full complement of PGA Tour tournaments, another aspect of this biennial affair continues to make matters difficult.

That is an American team that is constantly deep and consistently young.

How deep? Ten of the 12 players on the US team are ranked in the top 20 in the Official World Golf Ranking, and the only two who aren't check in at numbers 22 (Max Homa) and 26 (Kevin Kisner). The team features number one Scottie Scheffler and four others in the first 10 – Patrick Cantlay, number four; Xander Schauffele, number five; Justin Thomas, number seven; and Collin Morikawa, number nine.

How young? Two are just 25 years old (Morikawa and Cameron Young) and five others are in their 20s. As for the 'old' guard, we're talking Cantlay, 30; Max Homa, 31; Tony Finau, 32; and Billy Horschel, 35.

That's deep, that's young, and that's one potent group teeing it up next week at Quail Hollow Club in Charlotte, North Carolina.

It's an indication that the Americans will likely be heavy favourites to win for a ninth straight time. Then again, being the underdog is news to the Aussies, the South Africans, the Fijians, the Kiwi, the Canadians, the South Americans, the Japanese and the Koreans.

True, they've not yet come up with an answer to this biennial puzzle, but you'd be doing them a massive disservice if you sold them short. The big picture does them justice as you look at the 2021-22 season: four of their players (Matsuyama, Im, Lee and Kim) combined for five wins on the PGA Tour this season.

True, the Americans have bigger numbers (they combined for 18 victories this season), but Finchem's vision has played out as he predicted. International players have established global stature thanks to a high level of play on the PGA Tour and that will be prominently displayed in this year's Presidents Cup.

Focus on the individuals who'll make up the two line-ups, and not the past results, and you'll likely find 15 of the world's top 20 names. As promised more than 20 years ago, the Presidents Cup has reached a level of premier quality.

Will Zalatoris' bid to win the FedExCup is over after he withdrew from the Tour Championship due to a back injury.

The 26-year-old suffered two herniated discs during the third round of the BMW Championship last weekend and pulled out after the fourth hole.

Zalatoris had given himself a great chance of winning the FedExCup with his maiden PGA Tour triumph at the FedEx St. Jude Championship, but he will not be fit for the Tour Championship at East Lake this week.

The world number nine, who is third behind Scottie Scheffler and Patrick Cantlay in the FedExCup standings, will also miss the Presidents Cup at Quail Hollow next month.

If all 29 players complete 72 holes in Atlanta this weekend, Zalatoris will finish 30th in the FedExCup and pick up bonus money of $500,000, with the winner pocketing $18million

Allen Hobbs, Zalatoris' agent, said in a statement on Tuesday: "After Will’s withdrawal from the BMW Championship on Saturday, his medical team determined that the source of his back pain is two herniated discs. 

"Unfortunately, this means that Will is unable to play this week at the TOUR Championship. He is also very disappointed that he will not have the opportunity to play in next month's Presidents Cup, where he was hoping to play for Captain Love [Davis III] and represent the United States. 

"Will would like to thank his fans, sponsors, the TOUR, and his team for all of their support. He is fully focused on getting healthy and back onto the course as soon as he is able."
