Michael La Sasso arrived at The Club at Chatham Hills with one top-30 finish and no top-10s anywhere on his rookie LIV Golf card. He left it as a champion, and not just any champion. At 22, the reigning NCAA individual winner who gave up his Masters invitation to turn professional in January became the youngest player to win a LIV Golf event, holding off Jon Rahm and Bryson DeChambeau in a season finale that nobody saw him winning a week earlier.
The turn came out of nowhere and stayed there. La Sasso opened with a one-over 71 that suggested another quiet week for HyFlyers GC, whose season had been carried more by hope than results. Then, on the Friday, he shot 60. Bogey-free, every number falling, the kind of round that rearranges a leaderboard and a season in one afternoon. He followed it with a 66 to take the 54-hole lead into Sunday, and closed with a bogey-free 65 in the final round, hitting all eighteen greens in regulation, only the fifth time any player on LIV Golf had managed that all year.
A birdie he had to make
Sunday came down to the par-five 18th. La Sasso arrived at the tee with the lead but needing one more score to make it stand up, and the tournament account of his week is straightforward about what was required of him there: a birdie, with Rahm and DeChambeau both still moving on the leaderboard behind him.

His second shot from 229 yards did not find the green, finishing twenty yards short and left. What followed was the shot that decided the tournament: a chip that tracked in exactly the line he wanted and rolled out to within a foot of the cup, leaving a birdie putt he did not miss. “I just wanted to hit it as soon as I could,” he said afterward. “I saw exactly where I wanted to land it and kind of just drew it up perfectly, and it just kind of rolled out to be perfect.” The finish sealed a bogey-free 65 and a total of 18 under, one clear of the field.
The mistake that opened the door
Rahm made his own case for the trophy, closing with a 7-under 63 that would have been enough on almost any other Sunday. He had briefly taken the lead with a birdie at the 18th on his own card, playing the closing par four to a one-shot advantage before finishing his round on the first hole, where he missed an 11-foot par putt and made bogey. That dropped him into a tie, and handed La Sasso the exact opening he needed on the hole behind him. Rahm did not dress it up afterward. “My mistake opening the door,” he said. “Michael made a great up-and-down on 18 to win. He earned it, and as frustrating as it is for me, I’m happy about all the good things I did this week to give myself a chance.” DeChambeau’s closing 64 left him a further shot back in third, still enough to lock in his best-ever season-long individual ranking behind Rahm.
A team result to match
The team competition told a similar story from a different angle. Rahm’s Legion XIII, alongside Tyrrell Hatton, Caleb Surratt and Tom McKibbin, ran away with their second consecutive Team Championship by six shots, needing barely ninety minutes on Sunday morning to turn a one-stroke overnight lead into something closer to a procession. HyFlyers GC finished second, their best result in the team’s history, with La Sasso’s individual win doing most of the heavy lifting alongside a strong week from Scott Vincent. Captain Phil Mickelson, who has made just a single start of his own this season, watched from home and texted the team on Saturday night. “I know he was watching, said it was the most fun he’s had,” La Sasso said. “I’m thankful for everything he’s done for me.”
What La Sasso produced at Chatham Hills was his thirteenth event as a professional, and by his own admission not one he expected to be describing as a winning week when he stood over his opening tee shot on Thursday. Laurie Canter, who played in the final group with him on Sunday, put it about as well as anyone did afterward. “I knew he was a good player, but he’s had no form,” Canter said. “He’s a killer, isn’t he? He knows where it’s going. I love it. I think it’s great. I think he’s going to be great for golf.” On the evidence of one extraordinary week in Indiana, that is not a hard case to make.
