Posada out of lineup for son’s surgery

Yankees designated hitter Jorge Posada will be out of the lineup Wednesday night against Boston as his 11-year-old son undergoes surgery.

Posada’s son, Jorge III, suffers from craniosynostosis, which is a birth defect that causes one or more sutures on a baby’s head to close earlier than normal. The family is hopeful this will be the final surgery.

Posada went 3-for-3 Tuesday after replacing Mark Teixeira, who got hit in the knee by a pitch in the first inning.

"Hopefully he will be back [Thursday] if all goes well," general manager Brian Cashman said of Posada.

The Yankees lost 6-4 to the Red Sox in the series opener.
