List of World Series champions
The World Series is the annual championship series of Major League Baseball (MLB) and concludes the MLB postseason. First played in 1903, the World Series championship is determined through a best-of-seven playoff and is a contest between the champions of baseball's National League (NL) and American League (AL). Often referred to as the "Fall Classic", the modern World Series has been played every year since 1903 with two exceptions: in 1904, when the NL champion New York Giants declined to play the AL champion Boston Americans; and in 1994, when the series was canceled due to the players' strike.
Dutch Leonard (left-handed pitcher)
Leonard broke in with the Boston Red Sox in 1913. In his second year in the major leagues, , Leonard led the American League with a remarkable 0.96 ERA – the MLB record for single-season ERA when not counting Tim Keefe's record of 0.86 in his first MLB season, since it was only in 105 innings pitched. (The lowest ERA since then is Bob Gibson's 1.12 in 1968.) Leonard also pitched well in Boston's 1915 and 1916 World Series victories. He won Game 3 of the 1915 World Series, outduelling the Phillies' Grover Cleveland Alexander 2–1. He also won Game 4 of the 1916 World Series against the Brooklyn Robins.
