After 22 major league seasons, The Big Unit is walking away from baseball as one of the game's greatest pitchers. The 6-foot-10 Randy Johnson announced his retirement on a conference call Tuesday. "I really wanted to go out on my terms," Johnson said. "I just feel like there's not a lot more for me to do in this game. I just think it's a natural progression when you play this long. Eventually you have to say it's time."
