Baltimore Orioles designated hitter Mark Trumbo (knee) could return to the active roster this weekend if everything goes right. Trumbo is rehabbing his surgically-repaired right knee in Triple-A right now. He should be activated this weekend, assuming Trumbo doesn't suffer any setbacks. Renato Nunez has been playing well in the designated hitter role this season. Trumbo might be forced into a part-time player role, which will severely hurt his fantasy value.
