Joe Greiner has become one of the most talked-about caddies on the PGA Tour in 2025. Known for his strong rapport with top golfers and his deep understanding of the game, Greiner's recent moves have sent ripples through the professional golf community. Let’s explore Greiner’s journey, his new partnership, and what his evolving role means for the sport.

A Trusted Name in Professional Golf

Joe Greiner is no stranger to high-pressure situations on the biggest stages of golf. He built a rock-solid reputation while working with Max Homa, helping guide Homa to several of his career highlights. Their partnership was deep, based on both friendship and shared passion for the game. However, as reported by Yahoo Sports, Greiner and Homa recently ended their professional relationship to preserve their enduring friendship. Homa explained, "We always had a deal that we're friends first and friendship mattered more than the work thing."

The transition was bittersweet but done with mutual respect. Greiner briefly caddied for Justin Thomas this spring, stepping in while Thomas’ regular caddie recovered from injury. During this short period, Greiner helped Thomas secure a milestone win, solidifying his reputation as someone who brings out the best in his players.

The Move to Collin Morikawa’s Bag

In a significant shift for Greiner and the PGA Tour, Collin Morikawa, ranked fourth in the world, selected Greiner to be his new caddie. This major change, detailed by Golf.com, marks the end of Morikawa’s partnership with J.J. Jakovac—a duo that claimed six PGA Tour victories, including two majors. Such splits among elite golfer-caddie teams are rare, which is why Morikawa’s choice underscores just how highly Greiner is regarded within the touring community.

Morikawa’s decision also suggests a drive for further excellence. After several strong finishes but no major wins since 2022, the new partnership signals his commitment to elevating his game. “Morikawa is calling off a partnership that has been very, very good,” notes Golf.com, highlighting the belief that teaming up with Greiner could be even greater.
