Who is Max Homa’s caddie?

The California-born golfer is a multiple winner and popular figure on social media, but who is Max Homa’s caddie?

Max Homa has a long-time friend on the bag , as Joe Greiner has the job of walking the course with the PGA Tour star.

The pair have a close relationship that goes back to playing together at Vista Valencia Golf Club in California, where Greiner holds the course record on the Par-3 layout.

Greiner is clearly a talented player himself, having played collegiate golf at College of the Canyons, a community college in Santa Clarita, in the Western state.

However, Homa has turned to a couple of different caddies at the start of 2025.

His main man was unavailable for The Sentry, the first Signature Event of the season, and the Farmers Insurance Open.

So Homa called up Michael Greller, the longtime caddie for Jordan Spieth, for the first event before working with ex-caddie John Wood in California.

Despite never turning professional, Greiner would become a successful caddie for Max Homa, with the pair first joining forces in 2013.

It was only for a brief stint, though, before Greiner became the caddie of fellow American Kevin Chappell for a sustained period.

However, when Chappell had to have back surgery in 2019, Greiner took over caddie responsibilities for Max Homa, and the duo have remained together since.

Famous caddie Jim ‘Bones’ Mackay, who carries Justin Thomas’ bag and used to work with Phil Mickelson, has worked with Homa on a couple of occasions throughout his career as well.

That included a week at the 2021 PGA Championship, as the partnership was struck because Greiner had qualified for the US Amateur Four-Ball Championship.

Max Homa’s usual caddie returned immediately after, though, and it is no surprise due to the success they have found, most notably in recent seasons.

Homa claimed his biggest success in 2021 at Riviera Country Club, when he won the Genesis Invitational.

Since then, Max Homa has lifted several titles including the Fortinet Championship, the Wells Fargo Championship, and the Farmers Insurance Open.

• Who is Jordan Spieth’s coach?

The victories have come as no surprise to his caddie, as Greiner told Sirius XM PGA Tour Radio that “he’s got something special in him, that’s for sure”.

And he proved he is a special player by qualifying for the 2023 Ryder Cup, finishing inside the automatic spots to make his US debut for Zach Johnson’s team at Marco Simone Golf Club.

Meanwhile, Homa clearly trusts his caddie for advice on his game.

“I have a buddy I’ve sent videos to, and we’ve chatted about my golf swing,” he once said.

“Joe has taken a big role in checking ball positions and distance to the ball and things like that.”
