Jarrod Saltalamacchia, the Braves' elite hitting prospect coveted by many clubs, could be the centerpiece of a deal for a pitcher such as Marlins left-hander Dontrelle Willis, A's righty Rich Harden or one of the Angels' young starters. The Braves might want to make Saltalamacchia, a natural catcher, their future first baseman; they'll definitely need his offense if they lose center fielder Andruw Jones as a free agent.
