Tromp will start at catcher and bat ninth in Sunday's game against Atlanta.
He'll make a fourth consecutive start and appears to have supplanted Sam Huff as the Orioles' top option behind the plate while both Adley Rutschman (wrist) and Samuel Basallo (shoulder) are on the injured list. The owner of a career .218/.225/.360 slash line over parts of seven seasons in the big leagues, Tromp won't warrant much attention outside of AL-only leagues while he's operating as the Orioles' No. 1 backstop.
