John Smoltz is planning to return from the DL as a reliever in three weeks or so. This leaves the Braves with question marks in the rotation beyond Tim Hudson, Tom Glavine, and Jair Jurrjens.
The fifth starter job is often in flux for a lot of teams, but it seems the Braves need to figure out one more long-term starter for the year. The Braves do have some arms to bring up from Triple A, namely lefties Jo-Jo Reyes and Chuck James. Reyes has a 1.17 ERA in five starts.
In my opinion, the Braves need an innings eater if anything. Two trade possibilities come to mind: Joe Blanton and Kevin Millwood. I wonder if Billy Beane would demand top prospect Jason Heyward.
