Bob Feller

Wikipedia - "Robert William Andrew 'Bob' Feller (November 3, 1918 – December 15, 2010), nicknamed 'The Heater from Van Meter,' 'Bullet Bob,' and 'Rapid Robert,' was an American Major League Baseball pitcher. He was inducted into the Baseball Hall of Fame in 1962. One of the best right-handed pitchers in baseball history, Feller was a prodigy who entered the major leagues when he was 17. Feller played 18 seasons, all with the Cleveland Indians, from 1936 to 1956, his career interrupted by four years of military service during World War II. He became the first pitcher to win at least 20 games in a season before the age of 21, threw three no-hitters and 12 one-hitters (both records at the time of his retirement), led the American League in strikeouts in seven seasons, and pitched 279 complete games."
