Curtis Granderson stole third because Daniel Murphy told him to ... as a joke
Murphy joked for Granderson to steal third, so he did
Stealing third base in Game 2 of the NLCS isn't a decision to be made lightly. There's significant strategy involved, and a not-inconsiderable amount of confidence one must possess before taking off from second. Especially if you're doing it with one out in the inning, one false move can take you from scoring threat to inning-buster.
So when Curtis Granderson stole third in the bottom of the third inning on Sunday night, he probably put a lot of thought and concentration into the decision. He probably didn't swipe the base because Daniel Murphy, stationed at first, jokingly told him to.
Oh wait, he did? Let Murphy explain in his postgame news conference (around the 4:55 mark in the video at the top of this post):
Granderson had already stolen second that inning after drawing a leadoff walk, and he ended up scoring from third on Cespedes' single to put the Mets up, 4-0, and on their way to a 4-1 win -- so if he wants to steal on a joke sign from Murphy, by all means.
The Mets and Cubs will play Game 3 at Wrigley Field on Tuesday night, air time 7:30 p.m. ET on TBS, game time at 8 p.m. ET.
