Sixty percent of the Rangers' Opening Day starting rotation is now on the disabled list after Colby Lewis was placed on it Tuesday because of tendinitis in his right forearm. Scott Feldman will start Thursday for Lewis, who was replaced on the active roster by Martin Perez.
Perez will serve as the long reliever Tuesday and Wednesday. If he doesn't pitch, he could start Saturday. Justin Grimm, who gave up six runs in one-plus innings Monday, is also a candidate for that start.
Lewis said that the injury is similar to one he suffered in 2008 in Japan. He needed to be skipped only one start back then, but the Rangers will give him two days and the All-Star break to recovery.
The discomfort started June 17 against Houston and hadn't improved by Saturday, when he lasted only four innings and surrendered eight runs to Colorado. Lewis underwent an MRI exam Monday and received a cortisone injection.
"It is what it is, and we move on," Lewis said. "You can't look at what we've done and how many innings I've put up. It's just one of those things that you have to address. You have to listen to your body, and I'm going to listen to it and not push it."
Lewis was the Rangers' starter on Opening Day, and he leads the team with 100 innings. He joined the Rangers in 2010 after two seasons in Japan and has logged 87 regular-season and postseason starts.
General manager Jon Daniels said that the Rangers will determine their Saturday starter Thursday. Perez is coming off two solid starts at Triple A Round Rock after a session with Greg Maddux, a special assistant to the GM. Perez has been considered the Rangers' top pitching prospect for the past three seasons.
