Problem: Text: 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 (MLB) 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. (Tom Cheney struckout 21 in a 16-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.

Question: has any pitcher ever struck out all 27 batters?
A: no
