Lewis, a key contributor to the Rangers' rotation during their 2010 and '11 World Series runs, will throw again in extended spring training in Surprise, Ariz. on Saturday as he continues to come back from surgery to repair a flexor tendon in his right elbow last July. If all goes well, Lewis could begin his rehab assignment next Thursday, possibly for Triple-A Round Rock at Las Vegas.
Perez, recovering from a broken left wrist, made six starts for the Rangers last year. He had a 3.00 ERA in two outings this spring before getting hit by a line drive in a game against Seattle.
Both pitchers could return to the Rangers by the end of May, bolstering a Rangers pitching staff that entered Thursday third in the AL with a 3.30 ERA.
