Yadier Molina hit, what should have been a ground rule double, and ended up being a walk off RBI double. The Reds apparently didn't challenge the call in time or the Cardinals sabatoged their phone delaying the challenge and the game was over.
Cardinals haters really hate this. But MLB wants the Cards holding out hope until the last day. And if possible throw a game 163 into the mix before the playoffs. That would be the best case scenario for MLB.
