Hippo Vaughn

James Leslie "Hippo" Vaughn (April 9, 1888 – May 29, 1966) was an American left-handed pitcher in Major League Baseball. In a career that spanned thirteen seasons, he played for the New York Highlanders (1908, 1910–1912), the Washington Senators (1912), and the Chicago Cubs (1913–1921). Vaughn won over twenty games in five out of nine seasons for the Cubs, over seventeen games in seven of them.

His highlight year was , where he earned a National League-leading 22 wins when the season was ended a month early due to government restrictions brought about by World War I. That same year, Vaughn also led the National League in earned run average (ERA) and strikeouts to become the ninth triple crown winner in the modern era and the fifteenth overall. His nickname of "Hippo" came from his height of 6 feet 4 inches and weight of 215 pounds in an era where players averaged 5 feet 9 inches and 175 pounds.
