ST. PETERSBURG, Fla. -- The Orioles' Opening Day lineup was unveiled following the team's Monday afternoon workout with all the expected regulars in place for Tuesday's showdown against the Rays at 7 p.m. ET at Tropicana Field.

Second baseman Brian Roberts will bat leadoff with the rest of the order as follows: Adam Jones CF, Nick Markakis RF, Miguel Tejada 3B, Luke Scott DH, Matt Wieters C, Felix Pie LF, Garrett Atkins 1B, Cesar Izturis SS. Kevin Millwood will make the start and will be opposed by Tampa Bay's right-hander James Shields.

Reimold takes grounders at first base

ST. PETERSBURG, Fla. -- The Orioles don't know when or if it will happen, but the team appears to be entertaining the idea of putting left fielder Nolan Reimold at first base at some point this season.

"There's a lot that needs to be covered before you'd feel comfortable putting him out there," manager Dave Trembley said. "You've got to be fair to him as well as the other guys who are playing in the field with him. You can't just put somebody out there who's never done it before in a big league camp."

Reimold said his first taste of the corner infield spot, on one of the back fields at Ed Smith Stadium on the the last day of Spring Training was really just a ground-ball session that happened to be in front of the first base bag. He was approached by the team a few days ago about getting some work in at first base, a position he played regularly just once: during a summer of high school ball.

Trembley said the reason Reimold didn't get any looks at first earlier in camp was because the outfielder was still coming back from offseason surgery on his left Achilles tendon and wasn't 100 percent healthy until the final days of Spring Training.

After snapping an 0-for- 22 skid on March 21, Reimold managed to get his average up to .283, connecting for two homers and six RBIs in spring's final two weeks. Reimold's hot finish, combined with an impressive spring campaign from Opening Day left fielder Felix Pie, has the Orioles looking for ways to start both of them.

"Anything to stay in the lineup," Reimold said.
