I never said that many, if not more, of Babe Ruth's home runs couldn't have been of that variety (hell, there's a scene in his movie where he hit an inside-the-parker on an infield fly and had completely rounded the bases before the ball hit the ground; take ALL of these "legends" with a grain of salt). I'm just saying I've heard some historians say that up to a third of Josh Gibson's career home runs left the park on at least one hop.
