Derek Holland will make a rehab start tonight in Round Rock and is expected to get around 75 pitches, according to ESPN Dallas. Derek has already made one rehab start and he could be back in the rotation by as early as Saturday vs. the Twins. “That could change,” Washington said. “Write it in pencil so you can erase it.” If the Rangers do not go with Holland on Saturday, it is likely that Martin Perez would get another start. It is unlikely that it would be Justin Grimm, who was rocked in his second outing. Yu Darvish, who is scheduled to start on Saturday, would be moved to Friday is Holland gets the nod. So pay attention to Round Rock’s game tonight and see how Holland does. I am looking forward to getting him back in the rotation.
