OAKLAND -- The Rangers optioned left-handed pitcher Martin Perez to Triple-A Round Rock on Wednesday to make room for Colby Lewis, who was activated off the 15-day disabled list. Perez was 1-1 with a 5.54 ERA in two starts and two relief appearances since being called up on June 26. He was 5-5 with a 4.59 ERA in 15 starts at Round Rock. He left a positive impression with the Rangers while he was here. "I thought he was impressive," manager Ron Washington said. "For such a young kid, he handled himself very professionally. He gave us much more than we expected. We didn't know what to expect, considering he wasn't really lighting it up at Triple-A. But he made some adjustments and pitched well. He's certainly one of those kids we're not afraid to call upon if we have a need.
"He's just one of those kids that doesn't need to be sitting around. He needs to go down and keep pitching. But he was extremely impressive. He certainly has the stuff to compete. It's just not his time. We told him he needs to go down and dominate. He can dominate, now it's up to him. The fact that he got some time up here, we're looking forward to him pitching well down there. We'll be disappointed if he doesn't pitch well."
