It didn’t even look like he got all of it and going oppo with it, just seemed like a ball that in no way should get out. I'm with you. StatCast had it at 100.1 mph and it sure didn't seem like he hit it that hard. Looked gone off the bat to me.
It literally bounced over the wall. If the ball has enough arc to it, it can easily happen. I think it was around 2010 when Castro had it happen to him in the 9th inning of a game against Cincinnati or St. Louis and then Fukudome singled on the very next pitch to end the game.
