Posada's son, Jorge III, underwent another surgery for craniosynotosis, a birth defect in which the bones in the skull do not fuse correctly. Posada has said he hoped this would be the final surgery for his son, who has had numerous operations.
Although they were without Posada -- who has been used primarily as a designated hitter this season -- the Yankees did have first baseman Mark Teixeira back in the starting lineup a day after he was forced to exit upon being hit by a pitch from Boston's Jon Lester.
It was Posada who entered the game for Teixeira in the first inning on Tuesday. He went on to collect three hits, including his first two against a left-hander this season.
Through the Jorge Posada Foundation, the Yankees veteran and his family have raised money for those affected by the condition.
