Five-time Cy Young winner Randy Johnson, who won more than 300 games in his career, is retiring after 22 glorious seasons in Major League Baseball.
The left-handed American, who was nicknamed The Big Unit, made the announcement today.
The 46-year-old is a ten-time all-star who six months ago became the 24th pitcher in American baseball history to win 300 games.
Johnson won one World Series championship with the Arizona Diamondbacks in 2001.
He threw two career no-hitters, including a perfect game, and ranks second in career strikeouts.
The six-foot-ten-inch Johnson finishes with a career record of 303-166 and 4,875 strikeouts.
Asked what his biggest career moment was, Johnson said it was playing in the World Series and sharing the co-MVP honours with teammate Curt Schilling.
He captured his Cy Young Awards in 1995 with Seattle and from 1999-2002 in Arizona.
He compiled a 3.29 lifetime ERA with the Expos, Mariners, Astros, Diamondbacks, Yankees and Giants. His 4,875 strikeout total is second to Nolan Ryan who finished with 5,714.
