Sources: O’s calling up Gausman

The Baltimore Orioles hope this year’s high-profile midseason call-up is as good as last year’s high-profile midseason call-up.

The Orioles will promote right-hander Kevin Gausman from Class-AA Bowie to make his major league debut Thursday against Toronto, major league sources told

Gausman is reaching the majors less than one year after the Orioles selected him in the first round of the 2012 draft. 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, as evidenced by his otherworldly ratio of 49 strikeouts to five walks.

The Orioles’ aggressiveness with high-ceiling prospects was rewarded last year, when third baseman Manny Machado debuted at 20 and helped the team reach its first postseason since 1997.

When spring training began, Gausman wasn’t widely viewed as the top pitching prospect in Baltimore’s farm system. That distinction belonged to 20-year-old Dylan Bundy. But Bundy is on the disabled list and isn’t scheduled to resume throwing for another couple weeks due to a sore right elbow.

Gausman will become the 11th pitcher to start for the Orioles this season. He’s taking the place of Jair Jurrjens, who was sent back to the minors after making one start.
