The Orioles will call up No. 2 prospect Kevin Gausman to make his major league debut Thursday in Toronto, FOX Sports reports and MLB.com confirmed Tuesday. 

Gausman was not expected to be ready for the majors yet, despite speculation that he could be a viable option. Perhaps his last start for Double-A Bowie made the difference. Gausman earned a win as he allowed one run on four hits and one walk with 10 strikeouts over six innings. 

For the season at Double-A, his first as a professional after being drafted last year, he's gone 2-4 with a 3.11 ERA with 49 Ks over 46 1/3 innings. That said, he's allowed two or fewer runs to score in five straight outings.
