Murphy, who has a bone bruise on his right knee, said definitively on Friday that he will not play again this season. The Rangers have been operating on that assumption, but now it's final.
"There's no point now trying to get back," Murphy said. "I'm definitely feeling better over the course of the past week but, it's still not 100 percent, so there's no point in running out there and making it worse."
McCarthy had an MRI on the tendon in his right middle finger, and the results showed just a sprain. There is no tear or ligament damage, and no need for surgery. McCarthy still would like to pitch again, although he's running out of opportunities.
"Last time out there, I've felt as good as I have in a long time," McCarthy said. "Any time I get out there is of value. I don't want to go out on this note. I want to get back out there for my own well-being."
Benoit remains sidelined with shoulder inflammation, and there's no telling if he'll be able to pitch again this season.
"We haven't come to the conclusion to totally shut him down," Rangers manager Ron Washington said.
Jennings, who underwent surgery to repair a torn flexor tendon in his right elbow on May 30, began a throwing program on Friday. The program is designed to get him back to full strength in eight to 10 weeks, and he is expected to be ready for 2009 Spring Training. He is a free agent after the season and wouldn't mind coming back to the Rangers. It likely would be on a Minor League contract.
"They expressed interest in wanting me back right after the surgery, but we haven't talked since then," Jennings said. "There's been no need to talk. Obviously, being from here -- plus I like the direction of the club and the guys in the clubhouse -- I'd love to come back. I'll just see who needs pitching and what opportunities there are. I know what I can do if I'm healthy."
