At Fenway Park, Mickey Mantle opens the scoring in the 1st inning with a 3-run shot, then sandwiches a homer between round trippers by Bobby Richardson and Joe Pepitone in the 3rd inning in New York’s 6 – 5 win. The consecutive trifecta was last done for the Yankees in 1947, when Charlie Keller, Joe DiMaggio and Johnny Lindell connected. Richardson is 5 for 5 in the game. Mantle’s two homers today, his 37th and 38th at Fenway, will be his last in Boston, and tie him with Babe Ruth for most homers by a Sox opponent.
