Collin Morikawa has settled on a new caddie, at least for the next two weeks.

Morikawa is teaming up with longtime caddie Billy Foster for this week’s Genesis Scottish Open and next week’s British Open at Royal Portrush, according to . Foster will mark the fourth caddie that Morikawa has worked with this season after he parted with his longtime partner J.J. Jakovac in April.

Foster has worked with plenty of big names in the golf world throughout his career, including Seve Ballesteros, Darren Clarke and Thomas Bjørn. He most recently worked with Matt Fitzpatrick, and he was on the bag with him when Fitzpatrick won the U.S. Open in Massachusetts in 2022. Fitzpatrick and Foster split after The Players Championship earlier this season.

Morikawa and Jakovac worked together dating back to the start of Morikawa’s pro career, but the duo split in April. Since then, Morikawa has bounced around quite a bit. He worked with Joe Greiner, who split with Max Homa, for several events, and then brought on KK Limbhasut, his former college teammate at Cal, to caddie for him at the Rocket Classic last month.

Though Morikawa said his split with Greiner was amicable — he admitted that the two were “just on a little bit of a different page” — he got into a tense exchange with a reporter at the Rocket Classic over his caddie change. That marked just this season.

Morikawa enters this week’s tournament at The Renaissance Club at No. 5 in the Official World Golf Rankings. The two-time major winner has won six times on the PGA Tour, most recently at the Zozo Championship in 2023. He has four top-10 finishes this season, and he’s coming off a T8 finish at the Rocket Classic in Detroit last month.
