"He just needs to go out there and build up arm strength," Rangers pitching coach Mike Maddux said. "He's been deemed healthy and the rehab has gone well, now it's time for the Spring Training stretch. This is his Spring Training but it counts."
Lewis likely will add an inning and 15 pitches each time he takes the mound on the rehab assignment. Four starts will get him up to six innings and approximately 90 pitches. At that point he could be considered an option for the Major League rotation. He could end up needing more time but the Rangers will have to make a decision on activating him once the 30 days have expired.
"He's healthy and he's bouncing back well," Maddux said. "That's the big thing when you're coming back from a medical procedure, being able to bounce back the next day after you throw. He's been bouncing back. Now it's about regaining the touch and feel that Colby has always had, regaining the command."
