Rangers rehabbing starter Martin Perez pitched for Double-A Frisco Monday, ESPN reports. He threw 53 pitches -- 34 strikes -- over four innings and allowed an earned run on five hits and no walks with a strikeout.
Out since March 3 with a fractured wrist, Perez is not guaranteed to return to the rotation, when ready, MLB.com reports.
"No guarantees," manager Ron Washington said. "It's a possibility, but no guarantee. There's a difference."
With rehabbing Colby Lewis guaranteed a spot and rookies Nick Tepesch and Justin Grimm pitching fairly well, there may not be room for Perez when he's ready to return.
"I can only give you the circumstances when that becomes a reality, when I can sit down with everybody and we discuss what we think is best for us," Washington said. "But for me to say it right now when [Perez] just left Arizona, I don't think that would be right for the other guys that have an opinion."
