The Indians sweep a pair at Fenway Park, beating the Red Sox, 4 – 1, in 10 innings, and 9 – 5. A Ted Williams homer in the opener is the only Sox score, while Ken Keltner belts a pair of homers. They both add another in the nitecap, but Larry Doby clouts a monstrous two-run shot to dead center for the Tribe.
