Pedro Jaime Martínez is a Dominican-American former professional baseball starting pitcher, who played in Major League Baseball from 1992 to 2009, for five teams—most notably the Boston Red Sox from 1998 to 2004.
At the time of his retirement as an active player, his career record of 219 wins and 100 losses placed him fourth-highest in winning percentage in MLB history, and was the highest such achievement by a right-hander since the modern pitching era began, in 1903. Martínez ended his career with an earned run average of 2.93, the sixth-lowest by a pitcher with at least 2,500 innings pitched, since 1920. He reached the 3,000 strikeout mark in fewer innings than any pitcher except Randy Johnson, and is the only pitcher to compile over 3,000 career strikeouts with fewer than 3,000 innings pitched; Martínez' career strikeout rate of 10.04 per 9 innings trails only Johnson among pitchers with over 1,500 innings.
An eight-time All-Star, Martínez was at his peak from 1997 to 2003, establishing himself as one of the most dominant pitchers in baseball history.
