ARLINGTON -- Eric Hurley will miss his scheduled start on Friday with tendinitis in his right biceps. Tommy Hunter will be promoted from Triple-A Oklahoma to start in his place.

Hunter, the 54th overall pick out of the University of Alabama in the 2007 First-Year Player Draft, made just five starts with Oklahoma after being promoted from Double-A Frisco, and went 2-2 during that span, registering a 3.24 ERA in 33 1/3 innings. Hunter began the season with High-A Bakersfield. The Rangers haven't announced what roster move will be made to make room for Hunter.

"We feel Tommy gives us the best chance to win Friday's game," general manager Jon Daniels said. "He's young, but he's mature, and has a feel beyond his experience level. He deserves this opportunity."

On Tuesday, Hurley saw Rangers team physician Dr. Keith Meister, who advised Hurley to take a few days off to allow the tendinitis to subside.

"I can let it go right now," said Hurley of his ability to pitch without apprehension. "It's not so much that it's hurting -- it just doesn't feel like I want it to -- not free and easy. It's discomforting, and I don't want to go out there and change the way I throw.

"It's the first issue I've had, but I'd rather miss one month than one year."

As long as the injury heals as anticipated, the Rangers expect Hurley to make his next start.

In Hurley's last start -- his first since coming off the disabled list -- on Sunday, he pitched tentatively, allowing six runs in two innings to the Athletics. As a result, manager Ron Washington doesn't want Hurley on the mound if he's not 100 percent.

"I wouldn't want to pitch him through anything he isn't comfortable with," Washington said. "We saw what he looks like when he isn't comfortable."

By skipping his start Friday, Hurley hopes it will help keep him healthy down the stretch.

"I've learned a whole new aspect to baseball is being hurt and going to the ballpark and not being able to help the team," Hurley said. "I've been spending a lot of time in the training room, and I'm only 22. I don't want to be in the training room all the time."
