TGL announced on Monday that Jackson Koivun, 21, will join the league for the 2027 season. The standout from the Presidents Cup for the United States will team up with five-time major champion Brooks Koepka at the Motor City Golf Club, representing Detroit. This club marks TGL's first expansion, becoming the seventh team in the men's league, with Koivun and Koepka as the only announced members since the club's formation in May 2025.

Some of my best experiences have come while playing team golf, from winning national championships at Auburn to representing the U.S. at the Presidents Cup,

Koivun's addition aligns with TGL's goal of infusing the league with young talent. Notable young players like Tom Kim and Michael Thorbjornsen have paved the way for newcomers, with Koivun being the youngest at 21. He recently showcased his talent by being part of the winning U.S. Presidents Cup team at Medinah, where he finished 2-0-1 and defeated Si Woo Kim.

Having been mentored by Justin Thomas and surrounded by multiple-time major champions during the Presidents Cup, Koivun is poised for growth. With Koepka as a teammate, he is positioned to learn from one of the game's greats. Three months into his professional career, Koivun has already achieved significant milestones, including a win over the world No. 1 and participation in the FedEx Cup Playoffs. As he steps into his first full-time professional season, the expectations surrounding him continue to rise.
