Leaving Robison Field in mid-season, the Cardinals make their debut as the home team at Sportsman’s Park, also the home of the American League’s St. Louis Browns, bowing to the Pirates, 6 – 2. After signing a ten-year lease for $20,000 annually with Browns’ president Phil Ball, the team moves six blocks to be able to play its home games in a modern ballpark.

Going 5 for 5 in a 9 – 4 win over the Phils, Brooklyn’s Ed Konetchy gets his 10th straight hit, tying Jake Gettman’s record with Washington in 1897. Both will be topped by Walt Dropo in 1952.

Despite a state law banning Sunday baseball, the Robins play their first Sunday game in Brooklyn, charging regular admission and beating the Phils, 3 – 2. Charles Ebbetsannounces that the admission will benefit the Militia of Mercy, a wartime charity, and is for a pregame band concert and military drill exhibition before the game. When the band concert ends ticket sales stop to conform with the Sunday baseball laws. More than 12,000 attend. Despite the maneuver, Ebbets and manager Wilbert Robinson are arrested, and will pay a small fine.

Pittsburgh (Federal League) drops game 1, 6 – 0, at Baltimore, then scores in every inning of the nitecap to win, 13 – 5. This is the first game since 1894 in which this has happened.

At Pittsburgh, Chicago’s Wildfire Schulte breaks up a scoreless pitching duel between Marty O’Toole and Jimmy Lavender by legging out an inside-the-park homer in the 12th inning. Lavender and the Cubs win, 1 – 0.

Ty Cobb, who had an infield single off Earl Hamilton in his last game, on June 29th, repeats by beating out another infield hit against the St. Louis lefty. Again, Detroit wins, this time, 8 – 0.
