The Orioles will promote Kevin Gausman from Double-A Bowie to make his Major League debut on Thursday against the Blue Jays, according to a source.
Gausman was a first-round pick of Baltimore just last year.
He is 2-4 with a 3.11 ERA in eight starts for Bowie. Sources say the Orioles are comfortable with the move because of Gausman's ability to throw three pitches for strikes.
