The Pirates called up Elias Diaz on September 1st to be their third catcher in the majors. The decision to call up the top catching prospect signaled that he had moved ahead of Tony Sanchez on the depth charts, and the fact that Sanchez hasn't even been called up, despite the Indianapolis season coming to an end, further cements that idea.
Despite getting the call at the start of the month, Diaz has seen his time in the majors limited to just one at-bat. He hasn't spent any time in the field, which raises the question about why the Pirates aren't playing him.
