Randall David Randy" Johnson (born September 10, 1963), nicknamed "The Big Unit", is an American former professional baseball player. A left-handed pitcher, Johnson played in Major League Baseball for 22 seasons, in which he played for the Montreal Expos, Seattle Mariners, Houston Astros, Arizona Diamondbacks, New York Yankees, and San Francisco Giants. Johnson is a member of the 300 win club and the 3,000 strikeout club. The 6-foot-10-inch (2.08 m) Johnson was celebrated for having one of the most dominant fastballs in the game. He regularly approached, and occasionally exceeded, 100 miles per hour (160 km/h) during his prime. He also threw a hard, biting slider. Johnson won the Cy Young Award five times, second only to Roger Clemens' seven. He pitched two no-hitters, the second of which was the 17th perfect game in baseball history. Johnson finished his career first in strikeouts per nine innings pitched among starting pitchers (10.67), second all-time in total strikeouts (4,875; first among left-handed pitchers), third in hit batsmen (188), tenth in fewest hits allowed per nine innings pitched (7.24), 22nd in wins (303), and 57th in shutouts (37)."
