Baseball's Home Run Kings

573: Still muscle-bound more than 20 years after retiring from baseball, Hall of Famer Harmon Killebrew, shown in this undated photo, thinks even he could join the legion of hitters jacking balls beyond stadium fences this season. "If I was playing right now, I think I could probably hit 20 home runs,'' said Killebrew, who ranks fifth on the career list. "I could hit more, but you got to remember I'm 60 years old.'' During his playing days Killebrew was nicknamed "The Killer." (AP Photo)
