Minnesota’s Harmon Killebrew ties an American League record with four home runs in a doubleheader, a split with the Red Sox. Minnesota loses, 11 – 2, after winning the opener 13 – 4. The Killer has three homers in the lid lifter.

Kansas City beats New York, 5 – 3, despite homers by Yogi Berra and Mickey Mantle. For Yogi, it is his 358th and last home run.

At Wrigley Field, Jerry Lynch leads off the top of the ninth with a pinch-hit home run, which proves to be the difference in the Pirates’ 7-6 victory over Chicago. The historic homer is the southpaw slugger’s 15th career homer coming off the bench, establishing a new major league record previously shared with former Cincinnati teammate George Crowe.
