Sergio Garcia is adamant LIV Golf "is the future" for the sport as the PGA Tour fights to keep its stars out of the clutches of the lucrative Saudi-backed circuit.

It remains to be seen whether players signed up to the new series are kissing goodbye to playing the majors, which would be diminished by the absence of stars such as Garcia, Bryson DeChambeau, Dustin Johnson, Brooks Koepka and new defector Cameron Smith.

The PGA Tour has banned those players from its events for now, though they are still allowed to participate on the DP World Tour – previously known as the European Tour – whose sanctions have been put on hold until a hearing is heard early next year.

Ahead of this weekend's Boston leg of LIV Golf, Garcia told Stats Perform he had no regrets about committing to the controversial series, with the 42-year-old having been one of the first to sign up.

"Yeah, I love it. I think it's great. I think it's getting more and more momentum," the Spaniard said.

"I think that everyone is really enjoying the format and the way we're playing. We all believe that is the future of golf, keeping it fresher, even quicker and all the things that people are asking for. We're very excited about it."

There is a team element as well as individual honours at stake, while each event has so far been contested over 54 holes, rather than 72 as has long been the custom in the men's game. Players are joining on huge signing-on fees, while the level of tournament prize money is also proving appealing.

Saudi Arabia's often-criticised human rights record has led to accusations that LIV Golf is an attempt at 'sportswashing', looking to improve the reputation of a country by investing heavily in a glitzy event featuring widely admired international stars.

Garcia, the 2017 Masters champion, insists he has no problem with where the money behind the series originates.

"I think that a lot of people make business with Saudi Arabia and the government is fine. So there's nothing to do there," Garcia said.

"LIV Golf is international  Even this year, with just eight tournaments, we're playing some abroad. Next year coming up, there's going to be a lot more tournaments worldwide. So it definitely is [international]."

Paul Casey, an Englishman who won three PGA Tour titles and added 15 tournament wins on the European Tour, is another who has accepted a big cheque to join LIV Golf.

"I saw the first two events before my first event at Bedminster," Casey said.

He told Stats Perform he was impressed by "the energy", "the youngness of the crowd" and the "passion and excitement for everybody involved".

"This is like a start-up. This is something different," Casey said.

The likes of Rory McIlroy and Tiger Woods have insisted they will not be swayed by the huge sums on offer by LIV Golf, standing steadfastly by the PGA Tour and insisting it is that established circuit that is committed to golf's best interests.

McIlroy, who has played on Ryder Cup teams with Garcia and Casey, spoke recently of his opposition to LIV Golf, saying: "I hate what it's doing to the game of golf."

LIV is pumping enormous funds into the Asian Tour, too, with a host of LIV Golf players set to take part in that circuit's International Series.

Casey said: "A lot is always talked about growth of the game and stuff, and that is still an area where there is massive potential. There's been great growth in the game all over, but there's massive potential on the international front and I think the guys who are out here understand that and they're embracing it, and we'll see.

"I mean, I've always enjoyed playing international golf and enjoy playing golf certainly in Asia. And I'm looking forward to being in Bangkok, in Jeddah.

"There's rumours about maybe Australia or something like that as well coming back for us. So that's going to be pretty cool."

Big new signings hit the ground running in the first round of LIV Golf Boston, but after 18 holes at The International Golf Club it is Matthew Wolff and Talor Gooch tied for the lead at seven under.

While Gooch got to his 63 in a traditional fashion, posting eight birdies and one bogey, Wolff had far more ups and downs, making up for his three bogeys with six birdies, an eagle and a hole-in-one – the first ace in LIV Golf history.

One stroke behind the leaders are new arrivals Cameron Smith and Joaquin Neimann, after both played in last week's PGA Tour Championship.

Smith had five birdies and two eagles, showing off his firepower, but a double-bogey on the par-four 14th hole cost him a chance at the first-round lead.

After his round, Smith called it "great fun" and said "it was nice to see a familiar face" about his pairing with Dustin Johnson.

The rest of the field is at least two further strokes back, with Kevin Na, Bernd Wiesberger, Louis Oosthuizen, Paul Casey and Anirban Lahiri occupying the tie for fifth at four under.

The logjam at three under includes Dustin Johnson and Pat Perez, who along with Gooch and Patrick Reed (one under) have their Four Aces GC sitting second in the team standings. They trail only Hy Flyers GC, consisting of Wolff, Wiesberger, Cameron Tringale (one over) and Phil Mickelson (four over, 45th out of 48).

Bryson DeChambeau and Carlos Ortiz are at one under, and the Koepka brothers – Brooks and Chase – shot even-par 70s.

Serena Williams revealed how Tiger Woods encouraged her to return to tennis for one last glory mission after she powered into round three of the US Open.

Golf great Woods was on his feet and rapturously celebrating as Williams beat number two seed Anett Kontaveit on Wednesday night in New York.

He had been invited to sit in Williams' player box and shared conversations with Venus Williams as they watched Serena push past Kontaveit with a dynamic display, coming through 7-6 (7-4) 2-6 6-2 on Arthur Ashe Stadium.

It was remarkable from the 40-year-old on court as she found an extra gear for the deciding set, teeing up a clash with Australian world number 46 Ajla Tomjlanovic.

Williams has firmly indicated this will be her final tournament before retirement, and a host of stars have come out to watch her in action, with former US president Bill Clinton in the crowd for her first-round match.

Woods, actress Zendaya and film director Spike Lee were among those watching the Kontaveit match, and Williams suggested afterwards that she and 15-time major champion Woods had helped each other with their respective comebacks.

At this time last year, Williams was sidelined by a leg problem sustained at Wimbledon, while Woods was recovering from the serious leg injuries he suffered in a car crash.

"He's one of the reasons I'm here, one of the main reasons I'm still playing," Williams said. "We talked a lot. He was really trying to get me motivated.

"There's a few people, but we were like, 'Okay, we can do this together'.

"It was good, because I didn't know what I wanted to do. I was just lost, so many questions. When you can rely on someone like that, I mean, my goodness, he's Tiger Woods, it was really helpful to get clarity."

What Williams is wary of at this stage is raising her own expectations.

She was charmingly dismissive of an on-court question when asked if she was surprised by how well she was performing.

As far as Williams is concerned, she has proven countless times she is the greatest player, certainly of her own era, so even with limited preparation she backs herself.

But thinking too intently about winning majors may have been costly in recent years, with Williams having lost her last four grand slam finals to remain on 23 singles titles, one short of Margaret Court's all-time record.

"I cannot think that far," when asked about the prospect of winning the tournament. "I'm having fun and I'm enjoying it. Honestly, I've had so many tough matches the last I don't know how long that I just feel like just being prepared for everyone that I play is just going to be really, really difficult. Get through those moments."

In typical Williams fashion, she has danced around the subject of retirement since writing in Vogue in early August she would be "evolving away from tennis".

She spoke of wanting to "relish these next few weeks" in the magazine article, and so far at Flushing Meadows she is savouring every moment.

Serena and Venus were due to play doubles on Thursday, again on the Ashe Stadium court, with more fanfare expected.

"I think I've mostly been kind of blocking everything out, but then at the same time I've been embracing a little bit of it, because I also want to enjoy the moment," WIlliams said.

"I just feel like I have had a big red X on my back since I won the US Open in '99. It's been there my entire career, because I won my first grand slam early in my career.

"But here it's different. I feel like I've already won, figuratively, mentally. It's just pretty awesome the things that I've done."

Cameron Smith said he retains hope of featuring at the majors despite joining LIV Golf, as he labelled the lack of world ranking points on offer on the breakaway tour "unfair".

Smith, the current world number two, became the highest-ranked player to join the controversial Saudi Arabia-backed circuit on Tuesday, when he was announced as one of six new players ahead of this week's event in Boston.

The Australian, who clinched his first major title when winning the Open at St Andrews in July, joined compatriot Marc Leishman, as well as Joaquin Niemann, Cameron Tringale, Harold Varner III and Anirban Lahiri in signing up to the Greg Norman-headed tour.

Having reportedly agreed a deal worth over $100million to sign for the LIV Series, a decision which will earn him an indefinite suspension from the PGA Tour, Smith believes barring the circuit's players from majors is unfair on fans. 

"I hope that these world ranking points will sort themselves out before my exemption is up. I think to the fans of major championship golf, it may be a little bit unfair on them," Smith said.

"I think, you know, majors are about having the best guys in the best field on the best golf courses and hopefully we can sort that out.

"I haven't resigned my membership on the PGA Tour. I think my life has definitely changed over the last couple of months after the Open, I've had a few phone calls with players. 

"It has been a little bit different, but this, for me, was the right decision. I think this is the future of golf. I think it's been the same for a very, very long time and needs to be stirred up a little bit."

Aged 29 and ranked second in the world, the signing of Smith arguably represents one of the greatest coups managed by LIV to date, and he is hopeful the new circuit will soon be able to award rankings points.

"I think it's really a shame that we're not getting world ranking points out here," he added.

"I think, you know, to have 48 of the best guys around the world playing and not to get world ranking points, I think is perhaps a little bit unfair."

Meanwhile, Smith admitted upon joining LIV that the circuit had made him "an offer I couldn't ignore", but says being able to enjoy more time at home and play in his own country were also key motivations.

"Yes, it was a business decision as well. But you know, there's so many positives to come out of this thing," Smith said.

"For me, I haven't been back in Australia for three years. To spend more time at home, you know, not miss it out on friends' and family's weddings and you know, a couple of my friends have had kids over the last four or five years that I still haven't met. So that's going to be a part of my life that I can't wait to get back."

Asked whether there was anything the PGA Tour could have done to prevent his switch, Smith added: "Not particularly, to be honest. I think for me the biggest attraction was spending more time at home, getting that part of my life back. 

"It's something that I've really missed. I think obviously the pandemic that we've had over the last couple of years didn't really help out."
