Danny Duffy is scheduled to start on Wednesday against the Texas Rangers in Kansas City. The 22-year-old southpaw arrives in Kansas City after making seven starts for Triple-A Omaha this year, where he posted a 3-1 record with a 3.00 ERA. In 36.0 innings for the Storm Chasers, Duffy fanned 43 batters while issuing just 10 walks and holding his Pacific Coast League opponents to a collective .227 batting average.
Duffy was originally acquired by the Royals in the third round of the 2007 draft. Through five seasons in the minor leagues, the 6-foot-3 left-hander holds a career record of 27-14 with a 2.79 ERA.
