For the fifth time in the last six days, the Athletics and Senators contested a double header. The first of today's games, played in Washington, went to the Senators, 9-4, but for the second time in consecutive games, Nap Lajoie hit a pair of home runs for the A's. A's starter Snake Wiltse had a whale of a game in the afternoon tilt, firing a four-hitter, while rapping out two doubles and two triples, in a 13-0 walkover.

With catcher Harry Smith still out, manager Connie Mack signed William Diggins off the Chester Athletics as an emergency backup for the duration of the Boston series.
