The Athletics placed Ben Zobrist on the 15-day disabled list with a left knee injury, the team announced on Saturday. Zobrist has battled the injury for several days and tested the knee at designated hitter on Friday night.
To replace Zobrist on the roster, the A's called up Max Muncy from Triple-A Nashville. Muncy will make his Major League debut on Saturday, starting at third base and batting seventh for Oakland.
To make room for Muncy on the 40-man roster, the A's designated pitcher Eury De La Rosa for assignment.
Zobrist confirmed that he needs surgery on the knee and will be out four-to-six weeks.
