context_page_description: In baseball, a strikeout occurs when a pitcher throws three strikes to a batter during his time at bat. Twenty different pitchers have struck out at least 18 batters in a single nine-inning Major League Baseball game as of 2016, the most recent being Max Scherzer of the Washington Nationals on May 11, 2016. Four players have accomplished the feat more than once in their career; no player has ever struck out more than 20 batters in a nine-inning game. Charlie Sweeney was the first player to strike out 18 batters in a single game, doing so for the Providence Grays against the Boston Beaneaters on June 7, 1884. In spite of this, Bob Feller is viewed as the first pitcher to accomplish the feat, since his then-record 18 strikeouts was the first to occur during the 20th century and the live-ball era.
  Out of the twenty pitchers who have accomplished the feat, fifteen were right-handed and five pitched left-handed. Five of these players have played for only one major league team. Five pitchers—Steve Carlton, Roger Clemens, Randy Johnson, Nolan Ryan and Tom Seaver—are also members of the 3,000 strikeout club.
