The ball actually hit Baddoo and bounced into his glove. I'm not sure he even tagged him before his foot hit the bag but there's only seconds to challenge.
Probably some truth they checked out after the grand slam. They've gotten used to the bullpen shutting down the game. The problem was the defense gave up extra outs.
Baez, Haase, Vierling and McKinstry have been hot for a couple weeks with timely hits from Greene and RBIs from others. With the bullpen and the defense, if they get ahead, they are tough to beat.
