Luis Matos was placed on the 15-day disabled list with an inflamed right shoulder yesterday, further weakening an Orioles outfield that lost David Newhan earlier in the week.
The club called up catcher Raul Chavez from Double-A Bowie to fill Matos' roster spot. It had already recalled outfielder Luis Terrero to replace Newhan, who was moved to the 60-day DL yesterday.
Matos said he hopes to be on the DL no more than 15 days.
"The good thing is it is early and it is not that bad," he said. "You know, whenever they take an MRI, you think surgery, so it is good to know that it is a little thing that needs to go down and the swelling can go away and then I am going to feel better."
He said his shoulder has been sore since a jarring slide into second while stealing on Opening Day. His helmet crashed down and gashed his nose on the same play.
Matos uncorked several weak throws from center in the ensuing games, leaving manager Sam Perlozzo hesitant to start him.
"First of all, it is inflamed so we have to have it calm down and get the inflammation out of there," said Orioles vice president Jim Duquette. "And then, he'll have to go through a period of strengthening as well. So we placed him on the DL so we won't have to play short."
Matos was batting .138, but two of his four hits had been home runs.
Relief from Rodriguez
Eddy Rodriguez is the latest relief pitcher to be thrown into the breach between Orioles starters and late-inning specialists.
The club purchased Rodriguez's contract from Triple-A Ottawa after left-hander Tim Byrdak went on the DL with bone fragments in his elbow. Rodriguez pronounced himself a fitter and more complete pitcher than he was in 2004, when he posted a 4.78 ERA in 43 1/3 innings for the club.
Rodriguez had struck out seven in five scoreless innings for Ottawa.
"He's a lot more mature," Perlozzo said. "He doesn't panic out there. We needed somebody who was pitching pretty good to help us out."
The club's bullpen has struggled to cover the middle innings after Orioles starters have been removed early. Jim Brower and Chris Britton were ineffective in spelling starter Bruce Chen during Tuesday night's 15-1 loss to the Indians..
"Again, we'll keep experimenting until we find a mix to fix that," Perlozzo said. "Unless your bullpen is just outstanding, your starters have to take you deeper in the game."
Rodriguez - who allowed one run in two innings of mop-up duty last night - said he expected to make the Orioles in 2005, but instead spent the year at Ottawa.
"They said one of the reasons was I had to be in better shape," he said. "So I worked very hard over there to be ready over here."
Majewski's brief stay
Val Majewski's stay in Baltimore was short. The Orioles wanted him to get regular at-bats, so after one night, they sent him back to Ottawa and recalled Terrero.
The Orioles signed Terrero, 25, to a minor league deal after the Arizona Diamondbacks released him at the end of spring training. He's a .239 career hitter who has never shown much power in the majors or minors. He was batting .412 in 17 at-bats for Ottawa when the Orioles purchased his contract.
Perlozzo described Terrero as "kind of like a whole-package guy. He can run, he can throw, he can play good defense."
The manager said he will use his new outfielder to match up with left-handed pitchers and fill in for Corey Patterson in center field.
O's have 9th, 32nd picks
Major League Baseball announced the order for its June amateur draft yesterday. The Orioles will have the ninth pick overall and the 32nd pick as compensation for losing closer B.J. Ryan to free agency.
