Jorge Posada officially retired from baseball at a press conference Tuesday at Yankee Stadium. "I could never wear another uniform," Posada told the friends, family and press gathered around him. "I will forever be a Yankee." The 40-year-old was a five-time All-Star, collecting 1,664 hits, 275 home runs and 1,065 RBI during a 17-year major league career. He also won four World Series rings.
