Both teams end up having to use position players on the mound when a game between the Orioles and Red Sox goes deep into extra innings. O’s manager Buck Showalter turns to DH Chris Davis to take the mound in the 16th inning with the score tied at 6 – 6. Davis gives him a pair of scoreless innings, somewhat compensating for a brutal 0-for-8 game at the plate. The Sox face the same quandary in the top of the 17th, and turn to OF Darnell McDonald. Things don’t go so well, however, as he surrenders a three-run homer to Adam Jones; he then grounds into a double play against Davis to end the game in the bottom of the frame. Davis is the winner in the 9 – 6 Baltimore win, and McDonald the loser; it is the first time both teams use position players to pitch in the same game since October 4, 1925, when future Hall of Famers George Sisler and Ty Cobb both got to pitch on the last day of the season.
