The Yankees lost some potential outfield depth when Trayce Thompson — the brother of basketball star Klay — who was claimed on waivers Tuesday, was claimed by the A’s on Thursday.

But Clint Frazier, who has been out with a concussion, played in a simulated game in Tampa on Thursday — although it will be a while before he’s able to get to The Bronx.

“He continues to gain momentum,’’ manager Aaron Boone said before the Yankees’ 5-2 loss to the Orioles. “Hopefully now in the next couple of days, he’ll start to get into game action and start his spring training, game-wise and continues to progress. But things finally starting to ramp up, which is really good.”

The Yankees have been dealing with a depleted outfield, with Frazier, Aaron Hicks (oblique), Jacoby Ellsbury (oblique/hip) and Billy McKinney (shoulder) all on the disabled list.

Hicks could rejoin the team on Tuesday in Boston. Since he’s been down, the Yankees have played with just three outfielders on the roster, Brett Gardner, Aaron Judge and Giancarlo Stanton.

Boone said the Yankees would keep the roster that way “for now. We continue to evaluate that every day.”

Tyler Wade and Ronald Torreyes have been taking fly balls in center, but Boone said they are only doing that for “protection.”
