Oakland Athletics third baseman Matt Chapman undergoes successful shoulder surgery

The Oakland Athletics have announced that Gold Glove third baseman Matt Chapman underwent successful shoulder surgery on Friday.

Chapman, who this season won his first Gold Glove and the Rawlings Platinum Glove as the best defender in the American League, underwent surgery on his left shoulder by Dr. William Workman at the Bass Surgical Center in Walnut Creek.

Dr. Workman performed a distal clavicle resection procedure — also known as the Mumford procedure — designed to ameliorate shoulder pain and discomfort by excising the distal end of the clavicle. Dr. Workman, according to a team release, believes Chapman will be ready to swing in six weeks. The third baseman will begin physical therapy next week.

Chapman, 25, first felt symptoms in his shoulder while performing his off-season workouts. He was evaluated this week in Oakland.

This is Chapman’s second surgical procedure this offseason. He had hand and thumb issues this season,  necessitating surgery on Oct. 16, where Dr. Steven Shin performed an ulnar sided sesamoid bone excision along the right thumb at the Cedars-Sinai Kerlan-Jobe Institute in Los Angeles. Dr. Shin, according to a team release, was pleased with the outcome of that surgery and anticipates Matt to make a full recovery prior to the start of spring training.

This season, Chapman hit .278 (152-for-547) with 100 runs scored, 42 doubles, 24 homers and 68 RBI. He led the major leagues in doubles (25) after the All-Star break, and his 52 runs scored and 42 extra-base hits led the American League in the second half. The former first-rounder finished the second half with a .309 batting average, 14 homers, 39 RBI and .961 OPS, and became the first A’s player to score 100 runs in a season since Nick Swisher scored 106 in 2006.
