The Texas Rangers had already lost Colby Lewis for the season to surgery for a torn elbow flexor tendon, which made it an urgency to chase and land Dempster before the non-waiver trade deadline. Now they lose Feliz, who looked as though he were coming along well in three rehab starts at Round Rock (AAA) until elbow discomfort scratched him from a fourth start Sunday.
