Notes: Boredom sets in for Freel

Majewski optioned to Triple-A Louisville; Salmon called up

CINCINNATI -- Ryan Freel almost doesn't know what to do with himself. Rarely in his life has he ever been forced to be so inactive.

Almost three weeks ago, on May 28, Freel suffered head and neck contusions and a suspected concussion in an outfield collision with right fielder Norris Hopper. Freel was cleared on Friday to begin light aerobic activity.

Before the examination by head and spine specialist Dr. John Brannan, Freel had performed almost no physical activity while he recovered from the lingering effects of his injuries.

"In my 31 years of existence, this is pretty much the most time I've missed because of an injury or something," Freel said after the first of two 15-minute sessions on a bike on Friday.

"I've been bored and kind of disturbed, not being able to get in there and do something, whatever it may be. I mean, even hitting off the tee would have been nice. Just something."

Freel said that it felt good to simply get his body moving again.

"I haven't been doing a whole lot, so just being able to get on the bike, you know, it went by pretty quick," he said. "Just being able to move some parts of my body at a faster rate was nice. It felt good. I barely broke a sweat."

After the collision, it was uncertain as to how long it would take Freel to fully recover. But Freel has remained positive throughout the recovery process.

"I was always optimistic," he said. "I never even tried to think about my career being ended from that concussion. I stayed positive, but I was a little nervous at first, because I'd never felt these kind of effects."

Salmon up, Majewski down: Reliever Gary Majewski was optioned to Triple-A Louisville on Friday, one day after he couldn't retire a batter during a six-run seventh in the Reds' 9-7 loss to the Angels. Majewski, who struggled with a 15.88 ERA in 10 appearances since his May 24 callup, gave up two of starter Homer Bailey's runs plus three of his own while facing three batters.

"Majewski's just been a little inconsistent," manager Jerry Narron said. "He's been making good pitches, and it seems like he gets hurt by making one bad pitch. [Louisville will] give him a chance to get back and regroup and get it together, and, hopefully, help us sometime later in the year."

Also on Friday, right-handed reliever Brad Salmon was recalled from Louisville for the third time this season. Salmon has compiled a 2.87 ERA in 14 games and 15 2/3 innings for Louisville but has struggled in his time with the Reds, with a 4.50 ERA in 11 games.

Salmon pitched one inning in relief of starter Matt Belisle on Friday against the Rangers, retiring all three batters he faced and striking out one.

Hamilton back after dizzy spell: Rookie center fielder Josh Hamilton was back in the starting lineup on Friday. He left Thursday's game after five innings with complaints of fatigue, dizziness and lightheadedness.

Hamilton said that even though he has played through fatigue before, he did not want to risk playing while he felt ill.

"I can battle through the energy part," Hamilton said. "I just don't want to feel lightheaded. I've played on days when I didn't feel like playing, so I don't mind that. [On Thursday] I felt extra-tired. It was a day game, but at the same time, you usually wake up, eventually. I just didn't wake up."

Despite the high temperatures during Thursday's midday contest, Hamilton does not think he was dehydrated.

"I drink water all the time, but every time I drink water, 20 minutes after I drink it, my mouth is dried up again," he said. "It's like I can't get enough of it. I get full of it."

Instead of dehydration, Hamilton said, a blood test on Wednesday may have contributed to his condition on Thursday.

"They did all kinds of tests [on Wednesday]. I've got diabetes running in my family, [so they were] checking for insulin, checking my liver, any kind of bacteria in my blood, just all of the above."

Hamilton expects the results of the blood test at the beginning of next week.

Milton's surgery: Left-hander Eric Milton underwent season-ending Tommy John surgery to repair the torn ulnar collateral ligament in his left elbow on Friday. The two-hour operation was performed by Reds medical director Dr. Timothy Kremcheck.

Up next: The Reds will continue their three-game weekend series against the Rangers on Saturday at 7:10 p.m. ET at Great American Ball Park. Ace Aaron Harang (6-2, 3.93 ERA) will face Texas right-hander Jamey Wright (0-0, 16.87 ERA).
