Back injuries are tricky. It’s quite possible that Johnny Estrada is done for the season. It’s been more than a month since the collision and his back is only getting worse. Rest, therapy, and analgesics are pretty much all you can do; for now, Brian McCann is the starter, and the odds are that if the Braves make the playoffs he’ll catch not only the opener (with Smoltz on the mound) but all the games.
As you probably know, Brayan Pena was called up to back up McCann. Pena’s defensive problems were pretty evident, but I think he’ll eventually hit.
