Dr. William Workman performed a distal clavicle resection procedure on Chapman's shoulder, the team said Friday. Chapman is expected to begin swinging a bat in six weeks.
The team said Chapman felt discomfort in the shoulder during offseason workouts. Chapman also had surgery on his right thumb Oct. 16 and was expected to recover fully from that operation by spring training.
Chapman batted .278 with 24 home runs in a breakout season. He won his first Gold Glove and finished seventh in American League MVP voting.
