Boston Red Sox Minor League Pitching Coordinator
Ralph Treuel is the minor league pitching coordinator for the Boston Red Sox of Major League Baseball and a former minor league pitcher.
Treuel has spent his 38-year professional baseball career with two Major League organizations, the Detroit Tigers and the Red Sox. After attending college, he signed with Detroit in 1974 and pitched for nine seasons in the Tiger farm system, including service with the Triple-A Evansville Triplets from 19781980. He compiled a 5343 won-loss mark with a 4.11 earned run average in 193 minor league games. In 1983 he became the pitching coach for the Rookie-Level Bristol Tigers of the Appalachian League. In later assignments, he served as Detroit's roving minor league pitching instructor (19851990), pitching coach of the Triple-A Toledo Mud Hens (19911992) and field coordinator of player development (19931994). In 1995, Treuel was Sparky Anderson's pitching coach with the MLB Tigers, but left the Detroit organization following that campaign.
In 1996, he joined the Red Sox as pitching coach of the Double-A Trenton Thunder, and was promoted to his first term as minor league pitching coordinator from 19992001. From September 2001 through spring training of 2002, he was the Major League pitching coach of the Red Sox. From 20032005, Treuel served as manager of the Rookie-level Gulf Coast Red Sox then began his second term as Boston's roving minor league pitching coordinator in 2006. However, Treuel interrupted that assignment on an emergency basis to work as the Red Sox' MLB bullpen coach for four months of the 2006 season when surgery sidelined pitching coach Dave Wallace until August 8.
Treuel was inducted into the Elyria Sports Hall of Fame in 1990.
