Royals' Jackson Kowar: Moves up to Double-A

Kowar was promoted to Double-A Northwest Arkansas on Friday, Jeffrey Flanagan of MLB.com reports.

Last year's 33rd overall pick, Kowar recorded a 3.53 ERA through 13 starts with High-A Wilmington. He projects as a future back-end starter with the upside to be more than that, with his profile driven by strong velocity and a plus changeup.
