The Rangers have not set their rotation past Wednesday in Boston, mostly because they want to see how pitcher Colby Lewis performs Sunday for Triple-A Round Rock, according to The Dallas Morning News. If Lewis shows no issues with his surgically repaired hip, then he could start Friday against the Astros.
Joe Saunders would be the other option for Texas, but he's battling an ankle injury after getting hit by a one-hopper Friday. Saunders is expected to throw a bullpen session Monday, but manager Ron Washington doubts that will happen.
If Lewis and Saunders aren't ready to pitch Friday, then the team could place Saunders on the disabled list and recall Nick Martinez, who was optioned to Double-A Frisco Sunday following his first MLB start Saturday.
