He may have just returned from the disabled list last week, but Rangers pitcher Colby Lewis is done for the season. The former North High standout was diagnosed Monday with a torn flexor tendon in his right elbow and will have season-ending surgery later this week. Lewis was place on the diasbled list prior to the All-Star break with tendinitis to give the arm some rest. He returned on July 18 against Oakland and allowed only one run on three hits over five innings. However, his forearm tightness returned and Lewis skipped a bullpen session over the weekend. He was placed on the DL again Monday after being diagnosed with his latest injury. The 32-year-old is 6-6 for the Rangers this season with a 3.43 ERA and 93 strikeouts in 105 innings of work.
