Lewis is hoping to throw four innings and 60-65 pitches on Monday against Frisco. He'll likely get that start and two more. At that point, the Rangers will re-evaluate him to see if he's ready to return to the Major Leagues or needs more time on rehab assignment.
Lewis has not pitched in the Majors since July 18, 2012. He underwent surgery on July 27 to repair a torn flexor tendon in his right elbow and has been sidelined since. He made two starts in extended spring and began a medical rehabilitation assignment on May 9, pitching two innings for Triple-A Round Rock against Las Vegas.
Lewis' next outing was scheduled to be on Tuesday, but that has been delayed because of the triceps tendinitis. The Rangers recalled him from his rehab assignment while waiting for the inflammation to subside.
"I had this a little bit in 2010," Lewis said. "We got rid of it during the All-Star break and didn't miss a start. Hopefully this is the same situation."
