In 1939, the Red Sox purchased the contract of outfielder Ted Williams from the minor league San Diego Padres of the Pacific Coast League, ushering in an era of the team sometimes called the "Ted Sox." Williams consistently hit for both high power and high average, and is generally considered one of the greatest hitters of all time. The right-field bullpens in Fenway were built in part for Williams' left-handed swing, and are sometimes called "Williamsburg." Before this addition, it was over to right field. He served two stints in the United States Marine Corps as a pilot and saw active duty in both World War II and the Korean War, missing at least five full seasons of baseball. His book "The Science of Hitting" is widely read by students of baseball. He is currently the last player to hit over .400 for a full season, batting .406 in 1941. Williams feuded with sports writers his whole career, calling them "The Knights of the Keyboard", and his relationship with the fans was often rocky as he was seen spitting towards the stands on more than one occasion.
