Colin Morikawa's two-week tour of Scotland and Northern Ireland will come with a new caddie as he partners with Billy Foster, according to the golf site "bunkered."
Foster, of England, has worked for a slew of high-profile clients, the most recent of which was countryman Matt Fitzpatrick before the duo split earlier this season.
Foster has carried the bag for Spain's Seve Ballesteros, Northern Ireland's Darren Clarke and England's Lee Westwood.
Morikawa and Foster first will work together at this week's Scottish Open at the Renaissance Club at North Berwick, Scotland.
They will move on to the Open Championship at Royal Portrush from 17-20 July.
Morikawa won the Open Championship in 2021 at Royal St George's in Sandwich Kent, England.
After a split with caddie JJ Jakovac earlier this season, Morikawa has used multiple options on his bag, including former Cal teammate KK Limbhasut at the Rocket Classic in Detroit last month.
Morikawa, 28, is a two-time major winner who has six career PGA Tour victories, with his last at the Zozo Championship in October 2023.
