Jorge Posada, who just retired from his 17-year gig playing for the New York Yankees, has listed his Upper East Side apartment for $11.5 million.

Posada had merged two condos in The Seville building to create the home where he's lived with his wife and their two children, according to a report from Relocation.com. 

The condo has more than 5,000 square feet, four bedrooms, and 5.5 bathrooms, according to photos and a floor plan posted by The Real Estalker. The place also has a den, a laundry room and a breakfast area.

But the real home run is a master bedroom with two master bathrooms and his-and-her dressing rooms -- so he and Mrs. Posada can keep the mystery alive.

The sale news comes after the former catcher announced his retirement from baseball on Tuesday.

Playing for the New York Yankees has been an honor, he said at an emotional news conference. I could never wear another uniform.
