Alberto Castillo expected to join O's tomorrow.
We won't know definitively until tomorrow morning, but I'm told that left-hander Alberto Castillo is the guy who will be summoned to the majors to take Rhyne Hughes' spot on the roster.
It will be Castillo's second stint with the Orioles this year. He went 1-0 with a 5.40 ERA in six appearances for the Orioles before he was optioned back to Norfolk on May 5.
For Triple-A Norfolk this season, Castillo has a 3.38 ERA and two saves in eight appearances.
