Armed with sleep mask, Prince back, rested

SURPRISE, Ariz. -- Prince Fielder is back with the Rangers, sleeping soundly and ready to go.

Fielder is dealing with sleep apnea, and he was given a mask to wear at night when he goes to bed. Fielder, who underwent a sleep study in Dallas, said he had a good night's sleep on Thursday, and he could tell it has made a big difference.

"I wasn't breathing in my sleep," Fielder said. "They gave me a mask so I could sleep. They said if you stop breathing 30 times an hour while you're sleeping, that's extreme. I was at 39."

An estimated 18 million Americans, or 6.62 percent of the population, deal with sleep apnea. Former Ranger Mike Napoli had a severe case of sleep apnea that he finally overcame a couple of years ago.

"My wife told me I always snored loudly and stopped breathing in my sleep," Fielder said. "You don't feel it as much when you're young, but as you get older, it affects you more.

"I wasn't panicking, but I wanted to make sure. I was sleeping, but I didn't feel rested. Now that I know, I can sleep through the night. My wife can sleep, too, since I don't snore."

Napoli had to have his jaw broken to fix the problem.

"I don't think so," Fielder said. "I think I will stick with the mask."

Fielder is expecting that a better night's sleep will translate to better performance on the field.

"Believe it," Fielder said. "Believe it."

Worth noting

• Infielder Rougned Odor, sidelined with a sore right oblique muscle, is taking ground balls, but he is not yet ready to swing a bat.

• First baseman Ike Davis has been fitted with a brace on his right knee and is still day to day with a mild sprain.
