All-Star second baseman Roberto Alomar was placed on the 15-day disabled list by the Baltimore Orioles on Wednesday because of a pulled right groin muscle.
He was injured while running out a bunt in Baltimore's 5-4 victory over Texas on Tuesday night.
"He's real bad and there's no way [he can play]," Oriole Manager Davey Johnson said.
Alomar was replaced on the roster by Harold Baines, obtained Tuesday in a trade with the Chicago White Sox.
Alomar had to be helped from the field Tuesday and was still in noticeable pain Wednesday. He winced while raising his right leg to put on a sock before heading to the trainer's room.
"This is the worst," Alomar said. "At least I'm walking, but it's sore."
Jeff Reboulet will get most of the time at second base in Alomar's absence, with utility man Aaron Ledesma also expected to get some extra playing time.
Boston's Steve Avery pinch-hit in the 10th inning of Wednesday's game against Seattle, becoming the first Boston pitcher to pinch-hit since Tim Lollar in 1986. . . . Chicago brought up first baseman Mario Valdez from triple-A Nashville of the American Assn. to fill the spot opened when Harold Baines was traded to Baltimore. Valdez started in the 3-2 victory over Texas and had a two-run single. . . . Ranger catcher Ivan Rodriguez, believed on the trading block after refusing a $38-million contract offer, left the game at Baltimore in the second inning after being hit in the hand with a pitch. X-rays were negative.
