BALTIMORE -- Orioles manager Buck Showalter acknowledged it's been tough to get rookie Ryan Adams at-bats, but the young second baseman has still been enjoying his first taste of the Major Leagues.

"I didn't expect to be called up so this is -- I'm just happy to be here," said Adams, who has had just 12 at-bats since having his contract purchased May 20. "I could be down in Triple-A, playing every day, but I'm up here learning and this is an alternate road. So, I'm happy."

While the organization would prefer to get Adams regular playing time, a fact Showalter has alluded to multiple times, Brian Roberts' absence makes it necessary to have a backup at second base for Robert Andino. Eventually, the organization's plan is for Adams to be returned to Triple-A in favor of a more veteran player, to allow Adams to continue developing. But in the interim, Showalter hopes the 24-year-old Adams can use this opportunity to his advantage.

"As much as you tell him, it's kind of up to him just a little bit, too," Showalter said. "I watch [Adams] a lot during the games, see if he's watching the game. I'll go down there and ask him a question, what have you. He's engaged and I want the experience, for however long it lasts, to be a good one for him."

Adams hit .303 with a .434 slugging percentage in 39 games with the Tides before being promoted and he collected his first hit in his Major League debut on May 20. Although he has only started three games, Adams said he hasn't altered his pregame routine from the Minor Leagues and hasn't had any trouble staying engaged on the bench.

"Right now it seems my role is just being ready in case anybody goes down and if they ever need me late in a game," said Adams, who singled in a pinch-hit at-bat Friday. "I just got to be ready."

Jakubauskas likely to start Tuesday vs. A's

BALTIMORE -- With a four-man rotation, the Orioles will likely call on reliever Chris Jakubauskas to make a spot start for Tuesday's game against Oakland.

Manager Buck Showalter said following Sunday's 7-4 loss that the team will wait until Monday before making an official announcement, but Jakubauskas looks like the most logical choice. Long man Alfredo Simon was used for three innings on Sunday and would not be eligible to start, and both Chris Tillman and Brad Bergesen were optioned to Triple-A Norfolk last Sunday and couldn't be recalled in the 10-day period without it being an injury situation.

Jakubauskas, who was recalled prior to Monday's game in Seattle, has appeared in five games for the Orioles this year. All his prior appearances have come in relief. He tossed two scoreless innings in Friday's game against Toronto, lowering his ERA to a 6.39.

A starter for Triple-A Norfolk, Jakubauskas' last Major League start was for the Pittsburgh Pirates on April 24, 2010. In that game, he was hit near his right ear by Lance Berkman's line drive in the first inning and helped off the field.

The 32-year-old Jakubauskas has a career 6-8 record with a 5.59 ERA in 41 games, including nine starts. Given the team's upcoming off days, the Orioles won't need a fifth starter again until June 18's game at Washington.

Scott gets cortisone shot, hopes to avoid DL

BALTIMORE -- Luke Scott received a cortisone injection in his ailing right shoulder on Sunday, a measure the team hopes will continue to keep the outfielder, who was diagnosed with a torn labrum earlier this season, on the field.

Scott was not available to pinch-hit on Sunday, although he still petitioned his case to manager Buck Showalter, and the team is optimistic he will be a go for Monday's series opener against Oakland.

The Orioles are slated to face a pair of lefty starters in Gio Gonzalez on Monday and Josh Outman Wednesday and the left-handed hitting Scott probably wouldn't start either of those games, but would be available off the bench.

Scott has maintained that he will not undergo season-ending surgery on his shoulder, although it is clearly still bothering him at the plate. Coming off a career year offensively, Scott is batting .224 with six homers and 19 RBIs in 46 games, including a .151 average over his last 17 contests.

Asked if it might be worth considering shutting down Scott, Showalter said the team will continue to evaluate that option and figure out what's best.

"Only Luke really knows [how much the injury is affecting him] because he's not giving it up very much, at least not to me, and I talk to him about every day in some form or fashion," Showalter said. "He's a tough guy. He's going to try to play through it and we're hoping this injection kind of frees it up a little bit. If not, then what you're talking about [in shutting him down] is something that we might revisit."

Tidbits

• Top prospect Manny Machado was activated from the Minor League disabled list Sunday and will rejoin the Class-A Delmarva Shorebirds. The Orioles also announced that infielder Jonathan Schoop has been promoted to Frederick. Through 51 games, Schoop batted .316 for the Shorebirds with a team high eight home runs and 34 RBIs. Schoop also led the Shorebirds with 45 runs scored.

• Brian Roberts' return is still on a very inexact timetable, according to manager Buck Showalter. Roberts will be reevaluated by concussion specialist Dr. Michael Collins in Pittsburgh on Tuesday. He has been resting for the two weeks prescribed and the team should have a better idea as to when his return will be after his next appointment.

• The 128 homers Mark Reynolds had before his first grand slam Saturday was the most any active player had before hitting his first career slam.
