BALTIMORE -- The Orioles used virtually the same lineup in their second game as they did on Opening Day, but Baltimore manager Dave Trembley said on Wednesday that he'd like to switch things up before the end of the week. Trembley said the schedule would help him out in that regard, providing a foolproof reason to play his reserves.

The Orioles will face a couple of left-handed pitchers against Seattle this weekend, allowing Trembley to shift his lineup. They'll also play a day game on Sunday that follows a Saturday night game, affording another opportunity to spread around the playing time. According to Trembley, that's exactly what his team needs early in the season.

"I'd like to do that, but I haven't written the lineups out until the end of the homestand," he said. "It's easier said than done, especially with the bullpen. But you'd certainly like to get everyone an opportunity to get in there."

Baltimore carries a 12-man pitching staff, which limits the bench. Right now, Trembley is responsible for a backup catcher, a backup outfielder, a utilityman and a backup at both infield corners. Trembley has already provided some clarity by saying that his backup catcher, Guillermo Quiroz, will be paired with southpaw starter Adam Loewen.

Reserve outfielder Jay Payton can play all three outfield positions, which should keep him busy. That leaves just Brandon Fahey and Scott Moore to fend for themselves, and Trembley has said he's not sure how he'll use them. Fahey will likely be used more for defensive purposes, while Moore has been known for an offensive pedigree.

For now, Trembley seems inclined to let Fahey play whenever shortstop Luis Hernandez needs a break.

"Whatever he gives us offensively is a bonus. Defense is what I'm looking for," he said. "I don't know if it's once or twice a week. I don't know if it's play Luis three times in a row and give him a day off, then play Brandon. I know before this homestand is up I have to get Fahey in there. He's going to have to get a start at shortstop."

Moore, who's been taking ground balls all over the infield in anticipation of playing, has even said he'd be willing to play the outfield. The former first-round Draft pick was acquired from the Cubs last summer as part of a trade for veteran starter Steve Trachsel, and now he's willing to put all the necessary effort into carving out some regular playing time.

"I have no idea. I'm ready when they need me," said Moore. "I'm sure I'll get my opportunities late in the game when we need to make some switches as far as pinch-hitting and pinch-running. And I'll be ready for them."
