Colbrunn, 45, served as hitting coach for Boston in each of the last two seasons (2013-14). He missed part of the 2014 season after suffering subarachnoid hemorrhage in early June, and returned to the club in July. In his first year in his position, he oversaw an offense that led the major leagues in several categories, including runs scored (853), and slugging (.446) and on-base percentage (.349).
Following a 13-year playing career in the majors from 1992-2004 which included five trips to the postseason and a World Series title with Arizona in 2001, Colbrunn began his coaching career in 2007 with the New York Yankees' Single-A Charleston (SC) affiliate. He spent five additional seasons with Charleston before being named Red Sox major league hitting coach on November 28, 2012.
