Pedro Jaime Abreu Martínez, known as Pedro Martínez (born October 25, 1971), is a Dominican-American former starting pitcher in Major League Baseball who played for five teams from 1992 to 2009, most notably the Boston Red Sox. From 2002 to 2006 he held the major league record for the highest career winning percentage by a pitcher with at least 200 decisions; with a final record of 219 wins and 100 losses, he retired with the fourth highest percentage in history, and the highest by a right-hander since the modern pitching era began in 1893. He ended his career with an earned run average (ERA) of 2.93, the sixth lowest by a pitcher with at least 2,500 innings pitched since 1920. Martínez 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 strikeouts with less than 3,000 innings pitched; his career strikeout rate of 10.04 per 9 innings trails only Johnson (10.61) among pitchers with over 1,500 innings.
