Roberts dealing with bout of pneumonia

Second baseman experiences yet another setback

ARLINGTON -- Brian Roberts sent a text message to Orioles manager Dave Trembley on Thursday saying that he was "feeling better" after being admitted to a Baltimore-area hospital on Monday with pneumonia.

Roberts was supposed to go to Sarasota, Fla., for extended spring training on Wednesday. For now, Trembley doesn't know when that will happen. Roberts will remain in Baltimore until he is fully recovered.

Roberts is on the 60-day disabled list with an abdominal strain. He's also dealt with a herniated disk in his back and now pneumonia.

"It's just been one thing after another," Trembley said. "That says it all. When he thinks he's close and we think he's close, it's something else."

Scott gets starting nod over Atkins

ARLINGTON -- Luke Scott was in the lineup at first base Thursday night against Texas. He's likely to stay there during the weekend when the Orioles lose the designated hitter playing the Nationals in their ballpark with National League rules.

That means Garrett Atkins' job status could be in serious jeopardy. Atkins is hitless in his last 14 at-bats and is batting .221 with no home runs and six RBIs.

Scott, meanwhile, has hits in nine of his last 10 games. He's batting .459 (17-for-37) with six home runs and 11 RBIs during his hot streak.

"Luke Scott right now is swinging the bat well," manager Dave Trembley said. "We're going in to play the Nationals with no DH. I've got to try to find a way to get a lineup with the best eight guys in there for us. That's why you see Luke Scott play first base today, probably in anticipation of him doing that against the Nationals."

Trembley said the move obviously impacts Atkins for Thursday night and likely the weekend.

"Beyond this weekend, I couldn't tell you what's going to happen other than the fact that we'll have to see what move we make to add the other position player," Trembley said. "I don't think anybody could disagree that we have to do something to try and get some run production out of that position.

"That's probably the best way I can put it," Trembley added.

The Orioles currently are carrying 13 pitchers, and Trembley said he wants an extra position player in case of a double-switch playing in an NL park. The Orioles could go with another first baseman when they make a roster move Friday, calling up either Miguel Abreu or Scott Moore, which could further impact Atkins.

Uehara struggling with conditions

ARLINGTON -- Reliever Koji Uehara had to come out after 30 pitches in Wednesday's 4-3 loss to Texas after struggling with the heat and humid conditions.

As manager Dave Trembley said Thursday, "It's not even summertime yet." It was 85 degrees with high humidity. And while starter Jeremy Guthrie's six-inning stint might have been cut short by fatigue -- Guthrie said after the game it wasn't a factor -- the Orioles are troubled by Uehara's endurance.

Trembley mentioned after Wednesday's game that Uehara might need two days off to recover. Trembley backed off of that a little Thursday, but not all the way.

"We have to build him up into baseball pitching shape," Trembley said. "But I am concerned about it. Apparently there was an issue with it [Wednesday] night."

Worth noting

ARLINGTON -- Closer Mike Gonzalez (left shoulder strain) threw 18 pitches in an extended spring training game in Sarasota, Fla. "He threw OK," manager Dave Trembley said. "We were right around 89-90 mph." Trembley said pitching coach Rick Kranitz will come up with a program for Gonzalez now that he is ready for his baseball rehabilation and getting his arm in shape. ... Second baseman Ty Wigginton had his nine-game hitting streak snapped Wednesday. ... The Orioles continue to get good pitching. Jeremy Guthrie had a quality start Wednesday, giving up two runs in six innings. Orioles starters have 22 quality starts in 41 games this season.
