As you can see the biggest culprit was Hall of Famer Lefty Gomez. The other 1941 Yankee Hall of Fame pitcher was Red Ruffing who did not pitch against the second place Red Sox (84-70) that season. Ruffing did pitch against Boston in 1940 and 1942. It may have been an oddity of scheduling. Ruffing started game one of the World Series far more often than Gomez and that was true in 1941 against the Brooklyn Dodgers.

Williams may have been lucky against the Yankees in 1941. His BAbip was .492; next highest: .420 against Cleveland. Against all teams his BAbip was .378.

Williams BA:
home: .428
road: .380

His BA against the Yankees was over .400 both home and road.
