The Pirates announce that they have reinstated Jason Grilli from the disabled list and sent Tony Sanchez back to Indianapolis. We heard this week that Grilli hoped to return on Saturday, so he's a day early.
With Russell Martin's return, the Pirates would have had three catchers on their active roster, so it makes sense that they would option Sanchez. Fans fretted at the beginning of the season about the Pirates keeping Chris Stewart over Sanchez as a backup catcher, but Stewart has arguably outplayed Sanchez so far this season. (Stewart is also out of options, which of course is the real deciding factor in keeping him.)
