Taken from his Wikipedia page: ""Joseph Paul DiMaggio (November 25, 1914 – March 8, 1999), nicknamed "Joltin' Joe" and "The Yankee Clipper", was an American Major League Baseball center fielder who played his entire 13-year career for the New York Yankees. He is perhaps best known for his 56-game hitting streak (May 15 – July 16, 1941), a record that still stands. DiMaggio was a three-time MVP winner and an All-Star in each of his 13 seasons. During his tenure with the Yankees, the club won ten American League pennants and nine World Series championships.
