BALTIMORE -- The Orioles are still deciding what to do with Brian Roberts. Manager Dave Trembley said the second baseman was out of the lineup again on Sunday, battling abdominal problems, and the skipper said they're looking at the whole situation.

"We'll come up with a plan before the day is over [for] what direction we're going to go," Trembley said before Sunday's game. "Whether it's going to be a few days with Brian, or whether it's going to be the disabled list."

Trembley said Roberts is scheduled to get checked by a doctor Sunday, and the team is going to make a decision after that. After Sunday's game, Trembley said the club would make a decision on Monday.

"I'd prefer to have guys available to play," Trembley said. "It's a little tough when you're playing all these games in a row, and you got your best guy, leadoff guy, that can't play. If [the doctor] says seven or eight days, then I think you've got to do something else."

Gonzalez has work to do before closing

BALTIMORE -- Manager Dave Trembley said that if he needs a closer on Sunday, it won't be Mike Gonzalez, as the team is still working with the left-hander.

"I think we've still got some things we're going to do in the bullpen," Trembley said. "I wouldn't think [he'll pitch]."

Gonzalez has one save in three appearances and has blown two chances, getting a chorus of boos from the Baltimore crowd at the home opener on Friday afternoon.

The Orioles signed him to a free-agent contract in the offseason.

Trade for Lugo looking good now

BALTIMORE -- The trade the Orioles made late in Spring Training to get Julio Lugo as a backup middle infielder is looking very good right now.

Lugo has filled in for Brian Roberts and is likely to do so until the second baseman's abdominal injury heals. Lugo is batting .182 so far and was slated eighth in the lineup Sunday, but Lugo's good defense has been a big help in the first week.

"You need to have those people available, and he's been available," manager Dave Trembley said. "When you get a good recommendation from [Tony] La Russa, that ought to tell you."

Trembley concerned with two-out runs

BALTIMORE -- Manager Dave Trembley said he's puzzled as to why the Orioles have had so much trouble in two situations: giving up runs with two outs and allowing runs in the first inning.

Entering Sunday, O's pitchers had given up nine of 22 runs this season with two outs. Plus, they've had problems giving up first-inning runs to put the team in early holes. On Friday, Brad Bergesen allowed three runs in the first.

Plus, many of those situations involved batters in the bottom of the order. Trembley's not sure why it's happening but he hopes it will be over with soon, because it's been hurting the Orioles in the early days of this season.
