After an eight-season stint with the D-backs from 1999-2004 and 2007-08, Randy Johnson is the franchise's all-time leader in nearly every pitching category. Johnson leads all D-backs' pitchers in wins (118), strikeouts (2,077), complete games (38), innings pitched (1,630.1), games started (232), ERA (2.83) and shutouts (14). The left-hander won an unprecedented four consecutive National League Cy Young Awards from 1999-2002 and represented Arizona in the All-Star Game from 1999-2002 and 2004. Johnson set the club record with 20 strikeouts in a game on May 8, 2001 against Cincinnati, threw the only perfect game in franchise history on May 18, 2004 in Atlanta and shared World Series MVP and Sports Illustrated "Sportsmen of the Year" honors with Curt Schilling following the D-backs' World Championship season in 2001.
Overall, Johnson compiled a 303-166 record with a 3.29 ERA and 4,875 strikeouts for six teams during a 22-year career from 1988-2009. His 4,875 strikeouts are second all-time behind Hall of Famer Nolan Ryan. Johnson also became the 24th Major League pitcher to record 300 wins when he defeated the Nationals, 5-1, as a member of the Giants in Washington, D.C., on June 4, 2009.
