ARLINGTON (AP) -- Texas Rangers slugger Josh Hamilton is in the hospital because he has an intestinal virus.
The Rangers said Hamilton was being given fluids because of a virus going around in his family. He was expected to be released within 12-24 hours.
Outfielder Leonys Martin was recalled from Triple-A Round Rock and in the lineup for Friday night's series opener against Houston. Martin was batting ninth and playing center field.
To make room on the roster, the Rangers placed right-handed reliever Koji Uehara on the 15-day disabled list. Uehara's move is retroactive to Sunday, a day after he strained a back muscle pitching at San Francisco.
Hamilton, second in the AL with a .330 batting average, is tied for the majors lead with 22 home runs and has a majors-best 62 RBIs.
