He is second on the all-time strikeout list with 4,875 and his strikeouts per nine innings pitched rate of 10.6 is the best ever.
He also won a World Series MVP with the Diamondbacks in 2001.
Johnson, who pitched for the Giants in 2009 and joined the 300-win club in May, announced his decision during a conference call with the media.
