HOUSTON -- The Rangers are hoping pitcher Colby Lewis is experiencing just a minor setback in his recovery from flexor tendon surgery. Lewis pitched two innings in his first start on medical rehabilitation assignment Thursday night for Triple-A Round Rock and has developed some soreness in his right triceps muscle.
Lewis did not throw a scheduled bullpen session on Saturday, although he did play catch. He was supposed to make his second start on Tuesday against Tucson, but that is likely to get pushed back.
"It's not too dissimilar from what we see with a lot of guys in Spring Training," general manager Jon Daniels said. "My hope is that's all this is. We'll see."
Lewis, who underwent flexor tendon surgery on July 27, made two starts in extended spring training before beginning his 30-day medical rehabilitation assignment on Thursday against Las Vegas. He threw 41 pitches over two innings in the game, and another 12 in the bullpen afterward.
He is supposed to throw 60-65 pitches in his next start, although the Rangers don't know when that will be. Lewis doesn't expect to wait long.
"Not concerned, just arm getting back into throwing shape," Lewis told reporters by text message.
