Nope, I'm not joking. Chris Stewart was just pulled from the game after pulling up short on the base paths. He originally remained in the game to run, but Girardi decided to pull him in between innings. There are no other catchers on the Yankees' roster outside of Romine, and Bobby Wilson is the guy in Scranton that would probably get the call. In recent days, the Yankees have really talked up JR Murphy, though the extent of his experience is 299 plate appearances in Double-A.
Like always, I'll update this post when more news is announced.
UPDATE (10:39 PM): Girardi said that Stewart didn't hear a pop, but he's still getting an MRI of his groin.
