"The rehabilitation of Rangers right-hander Brandon Webb enters a new and more challenging phase Monday.

Webb will begin a 30-day injury-rehabilitation assignment with Double-A Frisco by starting against Tulsa, of the Colorado organization, in a 4:05 p.m. game at Dr Pepper Ballpark. It will be Webb's first true game appearance since April 6, 2009, when he worked four innings in an opening day start for Arizona.

In August 2009, Webb underwent surgery to remove debris and inflamed tissue from his right shoulder. Since then, he has faced hitters only in controlled situations such as batting practice and extended spring training games."
