The Orioles designated Huff for assignment Sunday.
Baltimore will keep three catchers on its active roster after Adley Rutschman (concussion) returned from injured list Sunday, but it's Chadwick Tromp who will stick around as the No. 3 option behind Samuel Basallo. After being called up from Triple-A Norfolk on June 6, Huff appeared in six games and went 2-for-14 with a double and a 0:6 BB:K.
