Colby Lewis made a rehab start this morning for AA Frisco, throwing 47 pitches in 2.1 innings with mixed results.
Colby cruised through the first two innings, allowing no baserunners and striking out 3 hitters. In the third inning, however, he allowed a homer, a double and a pair of singles before exiting with one out in the inning.
The reports on Twitter indicate that Lewis topped out at 87 mph with his fastball, which is somewhat concerning, although this is basically spring training for Lewis, and he has time to build the velocity back up before he's activated. Jon Daniels said this weekend that the Rangers were looking at the first week of June for Lewis to return to the rotation. Nick Tepesch, Justin Grimm and Josh Lindblom are currently holding down rotation spots in place of starters who are on the disabled list currently.
UPDATE -- Jeff Wilson writes that, while Lewis was at 85-86 mph today, topping out at 87, he wants to be throwing at 88-91 before being activated to face major league hitters.
