AA will make. He's running out of farm players to give away, but he'll certainly want to pick up another outfielder. The math for a 5th pitcher gets a lot tougher.
The big question is are the Braves still good enough to be confident in making the post season. They should be. This team is still loaded across the board, but they haven't been hitting like it lately. A 5th SP is only used during the regular season, so will AA be looking to shore up the regular season to ensure a post season birth, or shoring up the outfield and batting order for the post season?
He's got limited resources to go after both, so this might cement the strategy of cycling through minor league arms like they did last season with not horrible results. Not great and not even just good, but not horrible.
