The Kansas City Royals have optioned Yordano Ventura to Triple-A.

The 24-year-old right-hander broke out last season as one of baseball's best young arms.

Kansas City locked Ventura up with a five-year, $23 million deal prior to the 2015 season.

However, Ventura has pitched to a 5.19 ERA over 76 1/3 innings this year.
