BOSTON – Jordan Westburg is out of tonight’s Orioles lineup after injuring his right ankle last night in the first inning.

An update is coming later.

Samuel Basallo also is on the bench. Luis Vázquez is starting at third base. Dylan Beavers is in right field. Ryan Mountcastle is the designated hitter.

Coby Mayo is playing first base.

Tonight marks Tomoyuki Sugano’s 24^th major league start. He’s posted a 4.13 ERA in 126 1/3 innings, and he’s only the 10^th Japanese-born pitcher to win 10 games as a rookie.

Trades and injuries have torn apart the Orioles’ outfield, leading to a different kind of rebuild.

Cedric Mullins, Ramón Laureano and Ryan O’Hearn departed at the deadline. Colton Cowser went on the seven-day concussion list today, retroactive to yesterday, and Tyler O’Neill went on the 10-day IL with right wrist inflammation, retroactive to Wednesday.

In response, the Orioles signed Greg Allen to a one-year major league contract and he’s starting in center field tonight against the Athletics at Camden Yards. Ryan Noda is in right field and Dylan Carlson is in left.

Noda is making his third major league start in right. Carlson has much more experience but he’s in 0-for-28 and 2-for-35 slumps.

“We’ll figure it out as we go,” said interim manager Tony Mansolino. “We’ll play the hot hand. We’ll see what we’ve got. There will be a little platooning. We’re doing it today with Noda in right field.

The Orioles are making another series of roster moves.

They agreed to terms today with outfielder Greg Allen on a one-year major league contract. He’s wearing No. 25.

Allen, 32, is a switch-hitter who batted .270/.355/.440 with 14 doubles, a triple, six home runs and 32 RBIs in 61 games with Triple-A Iowa in the Cubs organization. He was released on Aug. 4.

Allen has a locker at Camden Yards.

Infielder/outfielder Vidal Bruján is gone. The Braves claimed him on waivers today.
