Departures of note

In the final doubleheader of the 1910 season, Jack O'Connor, player-manager of the St. Louis Browns, attempted to help Nap Lajoie win the American League batting title over Ty Cobb. With Cobb leading Lajoie .385 to .376, O'Connor ordered rookie third baseman Red Corriden to play in shallow left field, allowing Lajoie to bunt safely five times. On his last at-bat, Lajoie reached on a fielding error, which was scored as a hitless at-bat, lowering his average. O'Connor and coach Harry Howell then tried to bribe the official scorer, a woman, by offering to buy her a new wardrobe if she changed the call to a hit.

The scheme failed: Cobb won the title by less than one percentage point, .385069 to .384095. The outcry led American League president Ban Johnson to investigate. At Johnson's insistence, Browns owner Robert Hedges fired O'Connor and Howell and released them as players; both were informally banned from baseball for life. O'Connor accepted responsibility but said the idea came from players, and he did not object because the games had no bearing on the pennant race. It remains the most severe penalty ever given to a manager for in-game misconduct, tied with Pete Rose's lifetime ban for betting.

O'Connor, nicknamed Peach Pie, played 24 seasons as a catcher, outfielder, and first baseman for the Cincinnati Red Stockings, Columbus Solons, Cleveland Spiders, St. Louis Perfectos/Cardinals, Pittsburgh Pirates, New York Highlanders, and St. Louis Browns. He appeared in major league games in four decades, one of only 29 players to do so. He holds the record for most career stolen bases by a primary catcher, with 219. In 1981, research revealed that Cobb's statistics had been miscounted—one game was double-counted—and that Lajoie should have won the 1910 batting title.

O'Connor's managerial record with the Browns in 1910 was 47–107–4, a .305 winning percentage. He died in St. Louis on November 14, 1937, at age 71.
