Flanked by his wife and children, with five World Series trophies sitting on a table to his right, Jorge Posada announced his retirement Tuesday.

The five-time All-Star catcher ends his major league career after 17 seasons, all with the New York Yankees.

The 40-year-old Posada finished with a .273 career batting average, 275 home runs and 1,065 RBIs. Shifted to designated hitter last year, his playing time diminished.

Posada joins Bernie Williams and Andy Pettitte in retirement, leaving only 37-year-old Derek Jeter and 42-year-old Mariano Rivera from the core group that led the Yankees to four World Series titles in five years from 1996-2000.

In an emotional press conference at Yankee stadium, he thanked the fans across the globe and people from across the Yankees organization, including his fellow players.

"Especially Derek Jeter, who helped me stay focused, and positive, thank you buddy, hopefully you won't miss me that much."

With Jeter, Rivera and CC Sabathia looking on, Posada quoted Joe DiMaggio: "I want to thank the good Lord for making me a Yankee."

"I could never wear another uniform," he said. "I will forever be a Yankee."

Posada's voice broke up, especially when he spoke in Spanish.

Diana Munson, wife of the late Yankees catcher Thurman Munson, spoke about how Posada helped revive her interest in baseball, which had disappeared after her husband's death.

"I think he and Thurman definitely would have been best buds," she said.
