The Boston Red Sox have welcomed back Pedro Martinez into the organization, making him special assistant to the general manager.

Martinez played for the Red Sox for seven seasons (1998-2004) and was a key part of the 2004 team that brought a World Series title to Boston for the first time since 1918.

"We are very excited to have Pedro onboard with us and back in the Red Sox organization," Red Sox general manager Ben Cherington said. "He was one of the game's most dominant pitchers and without a doubt a beloved figure in Red Sox history. Similar to former teammate Jason Varitek, who joined the baseball operations staff in September, Pedro will be involved in several areas, including the evaluation, mentorship, and instruction of young players in Spring Training and throughout the season."

Martinez went 117-37 with a 2.52 ERA during his time with the Red Sox. In addition to having the best winning percentage (.760) in franchise history, Martinez ranks third in strikeouts (1,683) and sixth in wins (117).

"I am thrilled to be returning to this organization and to the city I love," Martinez said. "Ben Cherington's meetings this week have been outstanding. It is an honor to be back with the Red Sox and help in any way I can. I am grateful to our leaders; I believe in them, and I thank them for allowing me to return to the field and help us win again. My heart will always live in Boston."

The Dominican Republic native went 219-100 with a 2.93 ERA and 3,154 strikeouts in 476 career games (409 starts) for the Dodgers, Montreal Expos, Red Sox, Mets and Phillies.
