Jorge Posada made his major league debut at second base in Thursday's blowout of the A's. Manager Joe Girardi stuck Posada at second base in the ninth inning of a 22-8 game, and he handled an Anthony Recker grounder to end it, though he did bounce the throw to first. Posada was originally a second baseman in the minors, but this is the first time in 20 years that he's played the position in a game.
