I don't know, looking at replays again, the ball hit really high up on the wall, ten or so feet up. I'm not exactly sure whether he got his glove on it, but it looks like it might have bounced off the wall first and hit the back of his outstretched glove and fell. I think someone would have had to read the ball right, take a direct route, camp under the ball, and leap up to snag it before it hit the wall. A plus left fielder could probably do that more often than not. Average fielders or less, I'm thinking maybe not so much.
