Chavez placed on DL; Tolleson recalled

BALTIMORE -- The Orioles officially placed outfielder Endy Chavez on the 15-day disabled list prior to Thursday's game, recalling outfielder Steve Tolleson from Triple-A Norfolk in a move that was a necessity given the team's upcoming schedule.

"I'll be frank with you, if we weren't playing six National League games coming up, we might have waited," said manager Buck Showalter, whose O's travel to Atlanta and New York for a six-game road trip starting on Friday. "It's tough to have a three-man bench with one of them being a catcher and one of them potentially being Nick [Johnson]. We got to have some maneuverability there."

Chavez sustained a right hamstring strain in the sixth inning of Tuesday's game against the Pirates, and while he said on Thursday that he was feeling better, the team can't afford to have Chavez unable to play for the weekend.

"It's disappointing, but what can I say?" said Chavez, who is on the DL for the second time this season. "I feel pretty close, but I understand the situation with the team right now. They had to make a move, but it's not fun. It's disappointing. Hopefully, I'll get healthy pretty soon."

Chavez is the third Orioles outfielder inactive, joining Nick Markakis (right hamate bone surgery) and Nolan Reimold (herniated disk). Reimold, who is on the 60-day DL, was expected to get another MRI on Thursday to compare to his previous test.

Tolleson, who was sent down Tuesday to make room for Brian Roberts, was able to be recalled within 10 days because it was an injury situation. Tolleson drove to Triple-A Norfolk on Wednesday, unpacked, and then got the call to come back to Baltimore. He arrived Thursday morning.

"It's a much better four-hour ride coming back than it is going down," said Tolleson, who batted eighth and started in left field against the Pirates. "But that's kind of out of my control. I'm happy to be here and definitely happy to be playing."

Tolleson entered Thursday batting .237 with two homers and six RBIs in 12 games for the Orioles.

O's sign eight Draft picks, including Marin

BALTIMORE -- The Orioles have officially signed eight Draft picks, agreeing to terms with: Adrian Marin (Round 3), Torsten Boss (Round 8), Brady Wager (Round 9), Joel Hutter (Round 10) Sean McAdams (Round 14) Tommy Richards (Round 24), Anthony Caronia (Round 27) and Charles Porter (Round 35).

Marin is a high school shortstop out of Miami, Fla., while Boss was Michigan State University's third baseman. Wager is a right-handed pitcher from Grand Canyon University and Hutter is a shortstop out of Dallas Baptist University.

McAdams is a high school arm (Cardinal Mooney) and Sarasota, Fla., resident, and Richards is a second baseman from Washington State University. Caronia is a shortstop out of the University of Tampa. Porter is a 6-foot-3, 185-pound left-handed pitcher from Miami, who was listed without a school when he was selected because he actually gave up baseball briefly in favor of mixed martial arts.

The O's are expected to announce more signings over the next few days, since the contracts first have be approved by MLB.


• Reliever Matt Lindstrom threw off flat ground (60-100 feet) on Thursday and is scheduled to throw batting practice on Saturday. Assuming all goes well, Lindstrom will make a few Gulf Coast League appearances and then a few rehab games with Double-A Bowie.

• Nick Markakis (right wrist surgery) will travel with the Orioles to Atlanta and New York and has been doing some work with his left hand while trying to minimize the scarring in his right hand to speed up the healing process.

Showalter said Markakis -- who is hoping to return on the team's next homestand -- will have to go out and get some at-bats with an affiliate before being activated off the DL.

• Dontrelle Willis and Joel Pineiro threw simulated games on Thursday, with Willis going five innings and Pineiro going four. Pineiro is scheduled to pitch for the Gulf Coast League on Tuesday.
