SEATTLE -- Miguel Tejada said he's feeling good and will probably be back in the Orioles lineup on Tuesday night.

The Orioles third baseman, who suffered a strained hip adductor muscle in Saturday's sixth inning, said before Monday's game against the Mariners that he was feeling better and just about ready to go.

"I already told the manager that I'm ready to pinch-hit, and I'll see how I feel tomorrow," Tejada said. "Today, I'm feeling almost normal, and the trainer is going to take a little time to take a look at me and see how it goes. [I'll play] probably tomorrow or the next day."

The Orioles manager, Dave Trembley, didn't quite share Tejada's certainty, but he did say the infielder's condition had improved.

"He'll participate in some activities today according to his tolerance," Trembley said. "I'm hoping to have him back in the lineup before the series is over. I think he's going to test it today and let me know after batting practice."

With Tejada out, the Orioles started Ty Wigginton at third, moved Luke Scott to first base and had Julio Lugo at second in place of the injured Brian Roberts.

Roberts, Uehara on the mend

SEATTLE -- The Orioles had a few more pieces of news regarding injured players -- both reasonably promising.

Second baseman Brian Roberts, on the 15-day disabled list since April 12 (retroactive to April 10) with a strained abdominal muscle, saw spine specialist Dr. Lee Riley in Baltimore on Monday. As for reliever Koji Uehara, out since March 26 because of a left hamstring strain, the right-hander threw a simulated game Monday, tossing 35 pitches.

"He's progressing, but I couldn't tell you what the next step is or when he would be available," Trembley said.

Trembley said Gulf Coast league games or extended Spring Training games are possibilities for Uehara's upcoming rehab.

"I'm not sure," Trembley said. "I think he might have to. [Double-A] Bowie being close by might be a good spot for him. I think we've got to get to that point first before we can start scratching that out."

Scott makes first start of season at first base

SEATTLE -- Outfielder Luke Scott was told by reporters before Monday's game that he was making his first start of the season at first base. His facial expression did not change. If anything, there was a hint of a smile.

"I haven't played there in a while," he said. "But I'll be ready."

Scott, who has played in 10 games this year -- seven at designated hitter and three in left field -- had never played first base in four big league seasons before 2009, when he played 10 games there, making 54 putouts, three assists and turning four double plays. He committed just one error for a .983 fielding percentage and his last game at first base came on Sept. 11 at Yankee Stadium.

"It is a fun position," Scott said. "It's not as easy as people think. The ball gets on you quick. There's a lot that goes on there, but it's fun. It's no big deal. I took ground balls yesterday there."

Tillman having a rough go in Minors

SEATTLE -- Orioles pitching prospect Chris Tillman continues to struggle.

The 22-year-old right-hander, who lost out to David Hernandez in the spring battle for the fifth starter position, was rocked again in Triple-A on Sunday, allowing four runs and four hits in one inning. He's now 0-3 with an 8.38 ERA in three starts. On Sunday, Tillman also walked two batters, hit another and threw two wild pitches in a 42-pitch frame before being pulled.

"He didn't pitch well last night in Triple-A," Trembley said. "I hope he gets it straightened out. He's got a big upside for us and is someone we're counting on, but he didn't pitch well last night."
