The Mets need some help in their starting rotation, but Pedro Martinez isn't a likely option. Oliver Perez has been moved to the bullpen, Jonathan Niese left Sunday's start because of injury and John Maine threw 12 straight balls to begin his start on Saturday. According to a person with direct knowledge of the situation, the Mets aren't interested in reenlisting Martinez. He showed flashes of productivity with the Phillies in the second half of last season, but the Mets are worried about his age and durability.
