SCOTTSDALE, Ariz. -- Rockies pitcher Aaron Cook, who hasn't appeared in Cactus League action because of a sore right shoulder, said he is scheduled for an evaluation from Rockies medical director Dr. Thomas J. Noonan on Friday.

Cook, the Rockies' one-time No. 1 pitcher and expected to be a veteran rotation leader, has been either inactive or limited to playing catch for the last 10 days. The injury is being called inflammation for now, with simply time being the remedy. But the evaluation is to make sure. Noonan will arrive in Scottsdale on Thursday night.

"I asked 'Doogie' today, how could inflammation hurt the way it does?" Cook said Thursday. "It's inflammation in that joint up there that's taking awhile to go away."

Cook, 32, is looking to rebound from a 2010 season that saw him finish 6-8 with a 5.08 ERA and land on the disabled list twice, first with a hyperextended right big toe and later with a season-ending fractured right tibia, resulting from being hit on the leg with a line drive by the Reds' Joey Votto on Sept. 8.

"It's tough, but I also consider myself smart," Cook said. "I'm not going to go out there and do something that can be more detrimental for my career. Let's take the time we have in Spring Training to get it under control and make sure it's healthy, and that I'll be ready for the season."

Rockies manager Jim Tracy said Cook must throw bullpen sessions and face hitters before appearing in Cactus League play. Right-handers Esmil Rogers and Felipe Paulino are candidates for the rotation if Cook isn't ready.

Improved Ubaldo eyes Monday game outing

SCOTTSDALE, Ariz. -- Rockies ace pitcher Ubaldo Jimenez, scratched from a scheduled start Wednesday because of an infection at the base of his right thumbnail, said Thursday he plans to throw a bullpen Friday and return to Cactus League play Monday.

"I feel much better today," Jimenez said to a reporter.

Rockies come to terms with 27 players

SCOTTSDALE, Ariz. -- The Rockies reached contract agreements with 27 low-service time players, including regular outfielders Dexter Fowler and Seth Smith, and a starting rotation member, right-hander Jhoulys Chacin, the club announced Thursday.

Others who signed are right-handed pitchers Bruce Billings, Matt Daley, Edgmer Escalona, Clayton Mortensen, Juan Nicasio, Greg Reynolds, Cory Riordan, Esmil Rogers and Casey Weathers; left-handed pitchers Franklin Morales and Matt Reynolds; catchers Mike McKenry, Jose Morales, Jordan Pacheco and Wilin Rosario; and infielders Hector Gomez, Jonathan Herrera, Chris Nelson and Eric Young Jr.

Cook has empathy for tennis star's ailment

SCOTTSDALE, Ariz. -- The news that tennis star Serena Williams had to be treated last week for a blood clot in her lungs and again for a hematoma in her lungs hit home with Rockies right-hander Aaron Cook.

On Aug. 7, 2004, Cook left a start at Coors Field against the Reds with clotting in his lungs. Doctors removed the uppermost rib on his right side, and he missed nearly a calendar year of Major League action. Cook developed into an All-Star pitcher.

Still, he's constantly reminded how badly things could have gone. If untreated, the condition could be fatal.

"I tell people all the time it's something I'll never forget going through, because every day I look in the mirror I see scars on my chest," Cook said. "When I hear people going through stuff like that, I just feel for them and wish that they didn't have to go though it. Hopefully, she'll come through OK."

Cook said his understanding is the condition, known as thoracic outlet syndrome, often happens to healthy people who perform exercises or have jobs that require them to reach above their heads.

"Overhead motion creates a lot of stress with that first rib coming in contact with the collarbone, and that's where the pinching and clotting occurs," Cook said. "Tennis players, volleyball players, weightlifters who lift over their head, swimmers, it occurs even though they appear to be healthy and less resilient to things. It's something you can't really control. It's a more mechanical issue than anything else."
