BOSTON (AP) — The Boston Red Sox are looking for a new hitting coach.

Greg Colbrunn, who was the team’s hitting coach for the past two seasons, says he will not return for 2015.

The 13-year major leaguer oversaw an offense that led baseball in runs, slugging and on-base percentage last year, when the Red Sox won the World Series. This year’s team slumped and finished last in the AL East.

Colbrunn missed part of this season after suffering from bleeding on the brain.

The Red Sox announced Colbrunn’s departure on Friday.
