The Cubs have signed lefty reliever Francisley Bueno to a minor league deal, Matt Eddy of Baseball America writes. Bueno is represented by Praver/Shapiro.
Bueno, 33, pitched 32 1/3 innings for the Royals in 2014, posting a 4.18 ERA with 5.6 K/9 and 1.9 BB/9. He did not appear in the postseason, and the Royals non-tendered him after the season, even though he was not eligible for arbitration. He has a 2.98 ERA and 1.8 BB/9 in parts of four seasons, albeit with a low 4.9 K/9.
