It looked like a sure out. Chris Coghlan of the Toronto Blue Jays was heading for home, but a throw from the outfield to St. Louis catcher Yadier Molina got there first. Coghlan's solution? He dove over the catcher and executed a mid-air somersault onto home plate. See the video at MLB.com. He was ruled safe, and the Blue Jays went on to win 6-5. Mashable notes that the movie Major League II featured the same stunt.
"I was coming around third, and I looked to my left to see where the ball was," Coghlan recounts. "I saw it was going to beat me, and then, probably the last step or two, I saw Yadi go down. Your first thought is, 'OK, I'm going to run him over because he's right over the plate.' Then I was thinking, since he was down, 'Why don't you jump?' I just jumped, and the rest is history."
