At Cleveland’s League Park, Marty Kavanagh hits the first-ever pinch-hit grand slam in American League history. The infielder’s historic homer proves to be the difference as the Indians beat the Red Sox, 5 – 3. The ball rolls through a hole in the fence and cannot be retrieved in time for a play at the plate. Kavanagh’s blast comes off Boston’s Dutch Leonard and ends Boston’s seven-game win streak.

Allowing only one walk during a twin bill with the Cincinnati Reds, Grover Alexander of the Phillies wins both ends of a doubleheader, 7-3 and 4-0, to establish a National League record. The future Hall of Famer will repeat the feat on September 3, 1917, against the Brooklyn Robins at Ebbets Field.

1916 – Tris Speaker goes 4 for 6 and drives in a run as Cleveland edges Washington and Walter Johnson, 3 – 2.

At Philadelphia, the White Sox tie a major-league record when three pinch runners score in the 9th inning. The Sox win, 5 – 4, over the A’s.

Ernie Shore tops the White Sox, 4 – 3. The win, coupled with Detroit’s loss, allows the Red Sox to reclaim first place by .003. Boston will win three in a row from Detroit.

The Giants extend their win streak to 11 games by topping the Pirates in the opener of two. The nitecap is called after eight innings with the score tied, 1 – 1.

Washington’s Claude Thomas makes his first major league start and shuts out the A’s, 1 – 0.

At Comiskey Park, Boston lefty Babe Ruth wins his 20th, beating Red Faber and the White Sox, 6 – 2. A crowd of 40,000 is on hand, the largest turnout to date in Chicago history.
