Bruce arens used to say the best lessons are learned through great escapes from the games you almost lose and that is the latest game story from our Diamondbacks after a stout comeback yesterday in Miami they have swept another opponent atoning for that dog breath performance in Tampa and onwards they go to the Tinder Box of Boston and yet that comeback yesterday was necessary because Jordan Montgomery was once again highly overpaid and highly underwhelming thereby pushing the Diamondbacks to a conclusion they seem to be dreading where they seem to be dragging their feet and that conclusion is that Montgomery cannot be part of a fiveman rotation going forward these games are simply too important and Ryan Nelson has been a far better alternative despite his youthful in experience
