On Thursday, Martinez, a three-time Cy Young Award winner and eight-time All-Star, who spent seven seasons in Boston, was brought back to the franchise. He will serve as a special assistant to general manager Ben Cherington.
Martinez became a Red Sox starting pitcher in 1998 and was a key cog in the 2004 team that brought a World Series title to Boston for the first time since 1918.
With the Red Sox, he went 117-37 with a 2.52 ERA. He has the best winning percentage in franchise history, and ranks third in strikeouts (1,683) and sixth in wins (117).
