The Braves have the best catching prospect in baseball in Jarrod Saltalamacchia, who is having a monster start at Double-A Mississippi. Saltalamacchia is unlikely to replace current Braves catcher Brian McCann, so they would have to pull a position-switch with McCann or Saltalamacchia. The other option is to trade one of the, two with Saltalamacchia looming as the more likely scenario.
