The Orioles called up top pitching prospect Dylan Bundy to the majors, Fox Sports' Ken Rosenthal reported.

"The Orioles' game against the Mariners ended shortly before 4 a.m. ET. Bundy learned of his promotion in Florida via a phone call shortly after that, a source said."

Bundy, 19, was drafted fourth overall in 2011 out of Owasso High School. Originally, the team did not plan to promote Bundy this year and said they would send him to instructional league after his Double-A season ended. When asked last month about the prospects of calling Bundy up in September, manager Buck Showalter said,

"[Procedurally], there's some other things that happen if you do that....Right now, I want him to pitch his butt off and help Bowie win an Eastern League Championship. That's where I want his mindset. And then when that's over, look forward to working on some weaknesses down in instructional league with some very good instructors."
