He had a good reason, though -- his wife, Terryvette, went into labor with the couple's fifth child.
Ibanez, 40, left the clubhouse and immediately went to a local hospital to be with his wife. Ibanez did his part to deliver the Yankees to the AL East crown and the No. 1 seed in the American League.
On Tuesday, Ibanez hit a game-tying, ninth-inning homer and the game-winning, 12th-inning single. In the Yankees' 14-2 demolition of the Red Sox on Wednesday, Ibanez went 1-for-4.
Ibanez finished the season with a .240 average, 19 homers and 62 RBIs. He was signed primarily to handle the Yankees' DH duties, but with Brett Gardner missing most of the year, Ibanez spent time in the outfield.
