Fielder returns to Rangers' camp after sleep disorder tests (Yahoo Sports)

Slugger Prince Fielder returned to the Rangers' spring training on Friday and was inserted into the lineup as Texas' designated hitter against Milwaukee after being tested earlier this week for a sleep disorder. Fielder, who missed three games, went to the Dallas-Fort Worth area on Wednesday for tests, which determined he had sleep apnea, a potentially life-threatening ailment in which breathing stops and starts during sleep. Fielder had complained about having trouble getting rest.
