On August 4, 1911 — Lee Tannehill of the White Sox, the only SS to execute two unassisted double plays in one season, makes both of them in the same game versus Washington. Walter Johnson still wins 1 – 0 for the Senators in the first game of a doubleheader. In the second game, Germany Schaefer famously steals first base for the Senators. In the bottom of the 9th, with Clyde Milan on third base, he steals second in an attempt to draw a throw, in order to allow Milan to score. When that fails, he leads off second, and breaks towards first base on the next pitch, making it safely, and then, whil Sox manager Hugh Duffy is out arguing the call, he attempts to steal again. This time, Milan breaks for home and the White Sox throw him out to end the inning. The rules will be changed to prevent players from running the bases backwards in order to confuse the defence or make a mockery of the game, although backwards progress will still be allowed in case of genuine baserunning mistakes.
