Who Is Max Homa's Caddie? Meet Bill Harke

John Maxwell Homa, or 'Max' to most people, is a six-time PGA Tour winner who has represented Team USA at several Ryder Cups and Presidents Cups over the years. Since turning pro in 2013, Homa has continued to evolve as a golfer and went on to become one of the best in the world before a recent dip in form.

For much of his time as a pro, Homa had childhood friend, Joe Greiner on the bag. Homa met his long-time caddie when he was just six years old, with the pair going on to play golf together at Vista Valencia Golf Club in California - the place where Greiner holds the par-3 course record.

Greiner is a very good player himself and held aspirations of becoming a pro during his younger days, competing in mini-tour golf at one point, before falling into caddying and working with Homa during a brief stint in 2013. After looping for Kevin Chappell until he underwent back surgery in 2019, Greiner returned to Homa's bag and spent an extremely successful six years with the Californian.

The pair won several big PGA Tour events together, including two Wells Fargo Championships, two Fortinet Championships, a Genesis Invitational (2021), and the 2023 Farmers Insurance Open.

Their most recent success arrived on the DP World Tour when Homa landed the 72-man Nedbank Golf Challenge at Gary Player Country Club in Sun City, South Africa during November 2023.

However, since that point, Homa has fallen considerably down the world rankings, with a T3rd finish at The Masters in 2024 one of very few highlights. That caused the former World No.5 to make a change shortly before Augusta National in 2025, replacing Greiner with Bill Harke.

Speaking to the PGA Tour about his decision at the time, Homa said: “Joe and I made memories for a lifetime and can’t be more thankful for all the hard work. We have parted ways and it will be sad to see him go. I’ll always be grateful to have walked the fairways with one of my best friends.”

Harke, Homa's new bagman who started at the 2025 Valero Texas Open, is also a very good player having competed on the men's golf team at Cal State Monterey Bay during the early 2000s. After initially pursuing a career in golf as a PGA Apprentice, he began caddying on tour in 2004.

In his 20-plus-year career as a caddie, Harke has worked with multiple PGA Tour pros including Jonas Blixt, Colt Knost, Sam Ryder, Paul Casey, James Hahn, Ryan Moore, Chris Kirk, Min Woo Lee, and his long-time friend, Matt Every. His most-recent boss was Taylor Montgomery.

The Californian's first pro gig was with Janice Moodie on the LPGA Tour before he later moved on to work for Peter Tomasulo as the Korn Ferry Tour player earned his first PGA Tour card.

Homa's new caddie is not only highly experienced but also pretty successful, too, with victories alongside Kirk at the 2013 McGladrey Classic (RSM Classic) and the 2014 Deutsche Bank Championship in the FedEx Cup Playoffs.

Harke helped Blixt to the 2013 Greenbrier Classic title as well as the 2017 Zurich Classic, later going on to work with Min Woo as he claimed the 2021 Genesis Scottish Open.

His stint with the Swede only reportedly arrived after Blixt - who had missed seven cuts in a row - asked Harke for a lesson. The Californian helped Blixt out and then promptly won the week after. Blixt credited his stand-in looper for the success and then immediately hired him full-time.

Not only involved in caddying, Harke began volunteering with Academy of Art women's golf in 2023. During his debut campaign with the San Francisco-based school, he helped the team to a second-place finish at the Pacific West Conference Championship as well as guiding Academy of Art's players to a top-15 finish on 14 further occasions that term.

During his time away from tour golf, Harke has spent time as an instructor at Corica Park - a public course in Alameda, California which features an Australian links design - as well as the golf club's camp director for the Nike Adult Golf Camps.
