The crafty lefty acquired from the Cubs before the trade deadline will have a lot to prove as the season winds down. In his remaining starts, he has to prove that he is deserving of a spot in the playoff rotation first and foremost. After that, Maholm will have to prove that his $6M dollar team option is worth picking up.
Kris Medlen has asserted himself as a rotation staple going forward. Mike Minor's improvements are a great sign of things to come for the Braves future. Tommy Hanson is under contract for a few more years and Brandon Beachy should return at some point next year. If the Braves decide to bring back the always reliable Tim Hudson, then the number of available spots in the starting rotation begin to become more and more scarce.
The baby Braves that are knocking on the door to become future rotation starters is something the management can't ignore. Julio Teheran, Randall Delgado, and even Sean Gilmartin are all intriguing options for the Braves as they look to improve on the success of 2012.
Maholm will need to prove to the team that he is worthy of another shot in 2013.
