Jorge Posada's retirement will be officially announced by the longtime Yankees catcher and designated hitter during a press conference today at Yankee Stadium in New York. 

Posada's official website bore a short message Monday morning that seemed to indicate he will be retiring, though he is not expected to make the official announcement until 11 a.m. today.

Thank you for all your support, says the message, which is accompanied by a photo of Posada running to first base taken from behind.

Jorge Posada's retirement ends a long era for the Yankees in which the right-handed catcher helped the team win five World Series rings.

The plan for Posada's official press conference were reported Sunday night by the New York Daily News, which quoted a person familiar with the plans.

Reports emerged earlier this month that Jorge Posada, 40, planned to retire, but he has yet to make an official announcement.

Posada was one of the icons of nineties and 2000s-era Yankees baseball, joining Derek Jeter, Mariano Rivera, Andy Pettite and other greats on the road to a series of world championships and sports glory.

Jorge Posada steps down with a career .273 batting average, .374 OBP and 275 home runs.
