Check out the highlights from today's Reds vs. Pirates game. Brief description: Dunn is up to bat with 2 outs. Runners on 1st and 2nd. Dunn hits a flyball to centerfield, the centerfielder dives, the ball hits the grass and goes into his glove, but the umpire doesn't see that and calls him out. Reds fans and players go nuts, umps have a conference, overturn the call, and a run is allowed to score. Now, the ump clearly blew the call. But can you really overturn a 3rd out call like that, and then let a runner score? To me, it seems like that should be completely impossible. But it happened.
