5th The Brooklyn Superbas sweep two from the Giants, 8–0 and 4–2. Wild Bill Donovan pitches the opener, allowing 3 hits, in winning his NL-high 25th game. He does it in 45 appearances, starting 38. Christy Mathewson umpires the first game, then loses the 2nd game, also umpired by a ball player.
6th The Chicago Orphans close out their season with a 9-5 loss to the visiting Pirates. Tom Hughes allows just 4 hits for Chicago, but his teammates kick in with 9 errors, 4 by first baseman Jock Menefee to set a since-tied record (post-1893). This was only Menefee’s second game at 1B; he is normally a pitcher.
20th Seven Cardinals, including the 3 top hitters—Jesse Burkett, Emmet Heidrick, and Bobby Wallace—and half the pitching staff, jump to the new St. Louis AL team.
30th The Chicago Nationals hire Frank Selee as their new manager to replace Tom Loftus. Selee was recently fired as manager of Boston after 12 years at the helm. Selee will be inducted in the Hall of Fame in 1999.
