The 12 biggest former PGA Tour players teeing it up for the second LIV Golf event at Pumpkin Ridge

World rank: No. 19

Best major finish: 4 wins — PGA Championship (2018, 2019), US Open (2017, 2018)

LIV Golf team: Smash GC (captain)

One thing to know: Brooks Koepka is one of the latest former PGA pros to make an about-face on their LIV Golf stance. "They'll get their guys," Koepka said of the upstart league back in February. "Somebody will sell out and go to it."

At his first press conference with LIV Golf, Koepka refused to go into details regarding his change of heart. "Just my opinion, man," Koepka told reporters ahead of the Portland event. "My opinion changed."

World rank: No. 31

Best major finish: Win — US Open (2020)

LIV Golf team: Crushers GC (captain)

One thing to know: Bryson DeChambeau has been one of the biggest stories in golf over the past few years, bombing drives further than any other player on the PGA Tour. As the new team captain of Crushers GC, his team name certainly fits his style of play.

World rank: No. 84

Best major finish: 6 wins — Masters (2004, 2006, 2010), PGA Championship (2005, 2021), Open Championship (2013)

LIV Golf team: Hy Flyers GC (captain)

One thing to know: Phil Mickelson is still the biggest name in all of LIV Golf and will again captain Hy Flyers GC. This time around, he'll have three new teammates, with Bernd Wiesberger, Matthew Wolff, and Itthipat Buranatanyarat filling out his roster.

World rank: No. 17

Best major finish: 2 wins — Masters (2020), US Open (2016)

LIV Golf team: 4 Aces GC (captain)

One thing to know: Dustin Johnson remains the top-ranked player on the LIV Golf roster. With many of those above him in the rankings, including Rory McIlroy, Justin Thomas, Jon Rahm, and Collin Morikawa, pledging their commitment to the PGA Tour, it's unclear if that fact will change any time soon.

World rank: No. 39

Best major finish: Win — Masters (2018)

LIV Golf team: 4 Aces GC

One thing to know: Patrick Reed is another PGA Tour mainstay making his debut this weekend at LIV Golf's event in Portland. With teammates Dustin Johnson and Talor Gooch, Reed and the 4 Aces are the only team in LIV Golf to boast three players ranked in the top 50 in the world. No other team has more than one, and half of the 12 teams have zero.

World rank: No. 21

Best major finish: Win — Open Championship (2010)

LIV Golf team: Stinger GC (captain)

One thing to know: Louis Oosthuizen captained Stinger GC to victory at the first LIV Golf event in London, but was the only player on his team to not finish on the podium, with Charl Schwartzel taking first, Hennie du Plessis finishing second, and Branden Grace in third.

World rank: No. 96

Best major finish: 2nd — Open Championship (2008)

LIV Golf team: Majesticks GC

One thing to know: Ian Poulter was the captain of Majesticks GC for the London event, leading the team to a third-place finish in the team portion of the tournament alongside fellow Englishmen Lee Westwood, Sam Horsfield, and Laurie Canter. This week the same four men will make up the team, but Westwood will take up the captaincy from Poulter. The intricacies of roster decisions among LIV Golf teams are still quite murky.

World rank: No. 63

Best major finish: Win — Masters (2017)

LIV Golf team: Fireballs GC (captain)

One thing to know: Sergio Garcia has won just once on the PGA Tour since his Masters win in 2017. Still, given his standing as one of the greatest Ryder Cup players of all time, Garcia remains one of the bigger draws LIV Golf has to offer. At his press conference ahead of the Portland event, Garcia said he hoped that he'd still be able to compete on Ryder Cup teams, though given the relationship between LIV, the PGA, and the European Tour, that possibility remains in doubt for now.

World rank: No. 77

Best major finish: 2nd — US Open (2020)

LIV Golf team: Hy Flyers GC

One thing to know: Matthew Wolff is a good catch for LIV Golf — a young player still ahead of his prime that has already made waves at the highest level of the sport, including two top-five finishes at majors in 2020.

World rank: No. 22

Best major finish: T8 — PGA Championship (2021)

LIV Golf team: Fireballs GC

One thing to know: Abraham Ancer is another strong addition for LIV Golf ahead of its Portland event. He stands as the fourth-highest-ranked player on the roster, behind just Koepka, Johnson, and Oosthuizen.

World rank: No. 33

Best major finish: 7th — US Open (2016)

LIV Golf team: Iron Heads GC (captain)

One thing to know: Kevin Na's Iron Heads GC finished last in the team rankings at LIV Golf's debut event, with the team ending the weekend +16. Na will hope to improve on that this weekend in Portland with the help of two new teammates — Phachara Khongwatmai and Sihwan Kim.

World rank: No. 38

Best major finish: T14 — Masters (2022)

LIV Golf team: 4 Aces GC

One thing to know: Like Wolff and Ancer, Talor Gooch is not yet the biggest name in golf, but he's a player on the verge of being considered among the elites. As one of the highest-ranked players in the field this weekend, thanks to his strong play on the PGA Tour, Gooch was a captain at the first LIV Golf event, but in Portland he'll play under Dustin Johnson with 4 Aces GC.
