The Royals have designated Francisley Bueno for assignment, according to Bob Dutton of the Kansas City Star (on Twitter). The right-hander made his sole 2013 big league appearance yesterday, allowing just one hit in 2 and 1/3 innings.
This marks the second time this summer that the 32-year-old has been DFA'd by the Royals – he was also bumped off of the 40-man roster in late June to make way for the reactivation of Danny Duffy. In 30 relief appearances and one start at Triple-A Omaha this season, Bueno posted a 2.93 ERA with 7.3 K/9 and 3.1 BB/9.
