Shortly after exiting Thursday's game early with lower back tightness, Roy Oswalt acknowledged that the chronic ailment could end his career at some point. Oswalt said he has continued pitching despite the discomfort because "I don't want to be labeled a quitter." Additionally, he realized during Thursday's game that he "was not helping the team. I'm kind of a liability more than anything." The veteran starter isn't sure whether another cortisone injection will help, but also suggested that he would get fixed whatever needs fixing. With an MRI coming Monday, Oswalt will have time to consider his options before learning the results. Until then, it sounds like every conceivable scenario is on the table.
