Seventy-five years ago, "The Greatest Hitter Who Ever Lived" began his Major League career. Ted Williams debuted with the Boston Red Sox on opening day at Yankee Stadium on April 20, 1939, going 1-for-4 with a double in the only game he would ever play against Lou Gehrig. Three days later, he hit the first home run of his career, off Philadelphia Athletics pitcher Bud Thomas. Williams had 31 homers and 145 RBIs as a rookie. A two-time MVP who twice won the Triple Crown, Williams hit .344 lifetime with 521 home runs -- despite twice interrupting his career to serve as a Navy and Marine Corps pilot in World War II and the Korean War. Baseball's last .400 hitter, Ted Williams was always colorful and almost always controversial during the 22 years he played big league baseball.
