Maikel Franco and Freddy Galvis both went for a popup and it was impossible to tell who had it

Neil Walker popped up in the fourth inning of the Mets' 5-0 win over the Phillies on Sunday afternoon, sending the ball floating in between third base and shortstop. So, both Maikel Franco and Freddy Galvis went for it.
But which one of them caught it? They're so accomplished at mimicking each other that it's nearly impossible to tell which one of them actually intended to reel in the ball.

Franco, because he looked more at the ready? Or Galvis, who could've been sandbagging? Well, you have a 50-50 shot at guessing:
This isn't a trick question, either. One of them caught it, and Walker was retired for the first out of the inning.
The answer ...

Galvis, very casually. But honestly, it could've gone either way.
