Video: Nationals' Michael Morse hits invisible home run

"The events leading up to the phantom home run were every bit as confusing as they were bizarre.

Morse hit a deep fly ball which bounced off the fence. The umps signaled that the ball was still in play, then Morse was tagged out at first.

After review, the umps overturned the original call because the back wall at Busch Stadium is actually out of play, meaning Morse hit a grand slam.

So the umps sent everyone back to their bases. Morse went all the way back to the batter's box, pretended to swing the bat, then made his way around the bases."
