BALTIMORE -- The Orioles brought up Robert Andino, Nolan Reimold and Brandon Snyder on Wednesday as the first wave of September callups. The trio will be the first of a group anticipated to total anywhere from five or six extra players.

Given the Orioles' recent surge in starting pitching -- and fresh off a weekend sweep in which they held Anaheim to just one run -- Baltimore isn't inclined to call up extra arms right now and will try to hold off until Triple-A Norfolk's season ends on Monday.

To make room for Andino on the 40-man roster, outfielder Lou Montanez was designated for assignment. Andino will be used primarily to back up second base, given that Brian Roberts suffered a left hip strain in Anaheim and Julio Lugo took a ball to the head, requiring a CT scan. Roberts was a late addition to Tuesday's starting lineup against Boston and Lugo was available off the bench. While neither figures to miss an extended amount of time, Andino will add insurance.

Reimold was on the team's Opening Day roster, but he struggled at the plate and was sent to Norfolk on May 12. He has been hampered by offseason Achilles surgery and personal off-the-field issues, but he has heated up recently and enters Wednesday's game having batted .326 in August in Triple-A. Reimold will provide a right-handed bat in the outfield or off the bench, and he has also seen time at first base for Norfolk this season.

Synder struggled earlier in the season before going on the disabled list with a back/upper rib injury. Since being activated, he has hit .274 (29-for-106) with three homers and 13 RBIs entering Tuesday's game, and he figures to see some time at first base and designated hitter.

Markakis' 40th double makes history

BALTIMORE -- Following his first at-bat Tuesday night, Nick Markakis became just the 19th outfielder since 1900 to record at least four seasons with 40 doubles or more. Markakis, who belted the fateful two-bagger off Red Sox starter Josh Beckett in the Orioles' 5-2 victory, is now the first player in franchise history to post four consecutive seasons with at least 40 doubles.

"It's definitely something to be excited about," said Markakis, who is tied for the third-longest streak of 40-double seasons. "You just got to keep plugging away and go about your business. When you go out there and play hard every day ... you're going to have your struggles, but it's always good to get something like that."

Markakis is tied with Tris Speaker, whose streak of four consecutive seasons began in 1920, and trails only Joe Medwick (seven) and Harry Heilman (five) in that category. All three of those players are in the Hall of Fame, with Medwick's feat -- from 1933-39 -- the most recent.

Markakis had gone 45 at-bats between doubles before sending Beckett's 2-0 fastball into left field in the first inning for his 201st career double.

Showalter watches Machado's debut

BALTIMORE -- Orioles manager Buck Showalter used part of Monday's scheduled day off to take in short-season affiliate Aberdeen's game, where third overall pick Manny Machado was making his IronBirds debut.

"I went to see the Aberdeen IronBirds, not one player," said Showalter, who also chatted with owner Cal Ripken Jr. and met some of the organization's scouts as well as the IronBirds' coaching staff.

The 18-year-old Machado started at shortstop and went 1-for-3 at the plate, joining Connor Narron, who was Baltimore's fifth-round selection, and 2009 second-rounder Mychal Givens in a promising infield.

"[That's] pretty impressive [at] third, short and second age-wise," said Showalter, who has also made a trip to Double-A Bowie in his short time as Orioles manager.

"[Ripken Stadium is] a pretty impressive place."

Jones, Roberts return to Orioles' lineup

BALTIMORE -- Both Adam Jones and Brian Roberts returned to the lineup for Tuesday's series opener against the Red Sox, giving the Orioles their first regular group of starters in a week.

Jones hadn't played since exiting prior to the bottom of the fourth inning Aug. 24 after being hit on his left shoulder blade by White Sox starter Gavin Floyd in the top of the inning.

"He's still a little sore," Buck Showalter said of Jones, who had trouble running, catching and following through on his swing for the rest of the Orioles' road trip. "But I'm hoping he goes out there and the blood starts flowing and he gets into it."

The Orioles' everyday center fielder, Jones came in for treatment during Monday's off-day and said on Tuesday afternoon that he felt the best he had since suffering the injury. Roberts (left hip strain) was a later addition to the starting lineup given that Showalter wanted him to get through pregame batting practice first.

The club's leadoff hitter, Roberts missed most of Spring Training with a herniated disk in his lower back and didn't return to the team until July. He underwent a precautionary MRI on Monday which Showalter said went as well as can be expected.

"It alleviated some unknown where he was concerned as much as [anything]," Showalter said.

Julio Lugo, who was hit in the batting helmet with a pickoff throw in the first inning of Sunday's game, was also available for Tuesday's contest.
