This should force the Rangers hand in trading for another starter. Lewis was one of their better pitchers with a 3.43 ERA and a K/BB of 93/14. Greinke has been rumored so we'll have to wait and see.Colby Lewis will require season-ending surgery to repair a torn flexor tendon in his right elbow.
The procedure will be performed later this week. It's much better than Tommy John surgery, but it's still obviously a big blow to a Rangers team that will almost surely look to acquire a frontline starter now. It's not clear at this point whether Lewis will be ready for spring training next year or if his rehab will take longer than that.
