Kelley feeling 'great' after rehab outing

SEATTLE -- Mariners right-handed reliever Shawn Kelley came through a 14-pitch rehab outing on Monday at Triple-A Tacoma with flying colors.

"He said he felt great and averaged about 91-92 mph," manager Don Wakamatsu said. "He's going to throw Thursday in Everett [Wash.] and we'll try to extend him a little bit with two innings and then reevaluate at that point."

Kelley, a key piece of the bullpen, has been on the 15-day disabled list with right elbow inflammation since June 25, retroactive to June 16.

"It went good, real good," Kelley said. "It was nice. It was exciting. I just tried to get my work in and throw my pitches. It went as good as I could expect."

Kelley said it's just a matter of building his arm strength back to where could throw on back-to-back days.

"Being in a situation where it actually mattered, rather than bullpens or guys stepping in, was good," Kelley said.

Kelley had a 3-1 record and 3.96 ERA in 22 relief appearances.

Bedard will undergo third shoulder surgery

SEATTLE -- Mariners left-hander Erik Bedard will have surgery on his left shoulder on Friday, the team announced on Tuesday.

After being examined by Mariners medical director Edward Khalfayan, Dr. Lewis Yocum and Dr. David Altcheck, all three agreed that the third surgery in three years is needed.

Khalfayan and Yocum will perform the latest surgery.

Bedard, 31, had surgery on his left (pitching) shoulder on Aug. 14, 2009, to repair a torn labrum. He has spent the 2010 season rehabilitating following the surgery. Yocum performed the surgery in Los Angeles, Calif.

Despite periods of optimism during his rehabilitation this year, he was unable to make it beyond a rehabilitation assignment at Triple-A Tacoma.

Rookie catcher Moore 'up here to play'

SEATTLE -- Rookie catcher Adam Moore returned to the Major Leagues on Tuesday and has a chance to prove that he belongs in the Mariners' lineup regularly.

"We're going to play him just about every day," manager Don Wakamatsu said. "Obviously we'll look at some matches, and when it's a night [game followed by a day game], we might give him one off and let [Josh] Bard catch in that situation, but he's up here to play."

Moore replaces Rob Johnson on the 25-man roster.

The 26-year-old receiver batted .321 with three home runs and 15 RBIs with Triple-A Tacoma. He started the season with the Mariners, batting .193 with one home run and four RBIs before suffering a knee injury in May.

"I have been ready," Moore said. "I feel healthy and have been working a lot down there on being more consistent. I'm going to bring it up here, stay with my plan and continue to work on it."

Moore said he has a new stance, which includes holding his hands higher.

"I have been working my tail off on my offense," Moore said. "I feel comfortable right now."

He said one of keys to his success is getting to play regularly and not have to worry that if he goes hitless in one game he'll be on the bench for the next game.

"I've already experienced that," Moore said. "I've told myself not to let that happen again. I'm ready to go, and I hope it is my job, and I play every day."

Johnson batted .191 in 61 games for the Mariners. He hit two home runs and drove in 13 runs.
