Strikeouts in a major-league game: Tom Cheney, 21
The journeyman's performance was more a feat of endurance than one of domination. He needed 16 innings to reach the record mark with the Washington Senators in 1962. Cheney had 13 K's through nine innings and ended up tossing 228 pitches in the game. Roger Clemens set the record for strikeouts in a nine-inning game with 20 in 1986, a performance he repeated in 1996. It has since matched by Kerry Wood in 1998 and Randy Johnson in 2001.
