Baseball's most successful pitcher, Denton True "Cy" Young (1867-1955) won 511 games during his 22-year career, and compiled a record of sixteen 20-win seasons, including five seasons where he topped 30 wins. Young displayed remarkable consistency during an era of major rule changes. He began his professional career in 1890 with the Cleveland Spiders, where his fastball earned him the nickname of "The Canton Cyclone"—soon shortened to "Cy." In 1901, Young's first season with Boston was his career best: he led the new American League in wins, strikeouts, earned-run average, and pitched its first perfect game. In 1903, he won two games in the first modern World Series to help Boston win the championship. Young retired in 1911.
