On August 14, 1960 — The New York Yankees lose a doubleheader to Washington and fall to 3rd place in the American League, a half game behind the Orioles and White Sox. P Camilo Pascual’s grand slam is the difference in a 5 – 4 first-game win.

In the second game, Mickey Mantle, believing there are two outs, jogs to first base on a grounder to third. The Senators turn a double play, with New York’s Roger Maris suffering bruised ribs  sliding hard into second baseman Billy Gardner’s knee trying to break it up at second base. Maris will miss 18 games as a result. Mantle is heavily booed, and manager Casey Stengel replaces him with Bob Cerv. The clubs set a major-league record by using 17 pinch hitters – 9 by the Yankees – in the doubleheader (more than 18 innings), while playing a major-league record 24 errorless innings. The Yankees lose the second game 6-3.
