Louis Oosthuizen beat Bryson DeChambeau 1up in 23 holes to secure a spot for Stinger GC in the LIV Golf Championship in Miami on Sunday after a 2-1 team semi-finals win on Saturday.
Saturday's semi-finals were match play, with Sunday's Championship to be stroke play, but Oosthuizen and DeChambeau offered plenty of drama in their singles match at Trump National Doral.
With Stinger and the Crushers tied at 1-1, the pair could not be split until the fifth extra hole, with Oosthuizen having a long-range putt for victory fall short on the 18th hole.
But the South African swooped when DeChambeau's tee shot on the fifth extra hole found the water, with Oosthuizen finishing the job.
"At the end I think the adrenaline took over in the last few holes," the South African said. "It was a great match.
"I don’t know how many birdies we made, but very relieved now. I thought the boys had it covered so when I saw Branden [Grace] lost and I'm like 'oh boy I've got to do something here', so very chuffed."
Grace was beaten by Paul Casey in their singles match, but Charl Schwartzel and Hennie du Plessis had won 2up in the alternate shot against Charles Howell III and Anirban Lahiri.
Dustin Johnson and his 4Aces GC also advanced to Sunday's decider with a 2-1 win over Cleeks GC.
Pat Perez and Talor Gooch held off Graeme McDowell and Richard Bland in extra holes to clinch the winning point.
Cameron Smith's Punch GC knocked off Sergio Garcia's Firebirds GC 2-1, while Brooks Koepka's Smash GC were too good for Majesticks GC 3-0.
