Long-time New York Yankees star Jorge Posada announced his retirement from baseball today. The Puerto Rican catcher-designated hitter spent all of his 17 years with the Yankees and helped the Bronx Bombers win four World Series titles. Posada, who retires at age 40, said his passion for the game was dwindling: "I knew in my heart and I knew in my head I didn't want to play anymore."
