In the nitecap of a twinbill in Boston, Frank Arellanes tosses a one-hitter and the Red Sox collect 13 hits to defeat the A’s, 10 – 1. Light-hitting Simon Nicholls clubs his 4th homer of the year for the only A’s hit.

In a game, the significance of which will not be recognized for another three weeks, the Pirates and Cubs are tied 0 – 0 in the last of the 10th at Pittsburgh. With two outs and the bases loaded, Pittsburgh’s Owen Wilson singles to CF, scoring Fred Clarke with the winning run. Warren Gill, on first base, does not get to second but stops short, turns, and heads for the dugout, a common practice. The Cubs’ Johnny Evers calls for the ball from Jimmy Slagle, touches second, and claims the run does not count as Gill has been forced. The lone umpire, Hank O’Day, has left the field. When queried, he rules that Clarke had already scored, so the run counts. The Cubs protest to league president Harry Pulliam, but are denied. This is the first time the Cubs try this tactic, but not the last, as the Fred Merkle game will demonstrate.

The Giants sweep two more from the Doves, beating Boston, 3 – 0 and 8 – 5. Joe McGinnity wins the first game, while three pitchers combine for the second win. Red Ames is the victor.

In New York, Walter Johnson opens a series against New York by besting Jack Chesbro, 3 – 0, allowing six hits in the Washington win.
