A’s rookie Mickey Cochrane hits three homers to lead Philadelphia to a 20 – 4 rout over the Browns. His first two clouts come off Milt Gaston, and the third off George Blaeholder. He will hit just another two all year to total six.
The Giants’ George Kelly sets a major-league record by homering in the 3rd, 4th and 5th innings against the Cubs’ Vic Aldridge as New York rolls to a 13 – 6 win. Kelly adds a single and double to run his total bases to 15 for the game. Kelly has now hit a record six homers off cousin Aldridge this year, a mark off one pitcher that will be tied by Ted Williams (in 1941, off Johnny Rigney) and Ted Kluszewski (in 1954, off Max Surkont). Kelly is the first player to homer in three successive innings.
At Sportsman’s Park, Ken Williams of the St. Louis Browns hits three home runs and two singles in the Browns’ 10 – 7 victory against the Chicago White Sox. Williams is the first American League player to hit three home runs in a game. Given a head start on the suspended Babe Ruth, he will take the American League home run and RBI titles and become the first 30-30 man, with 39 home runs and 37 stolen bases.
