A tough night for Duffy (8-11) on Wednesday, allowing five runs, but only one earned, while walking one and striking out six over seven innings in a loss to the Rockies. Third baseman Christian Colon's error lead to a Matt McBride grand slam that put Duffy and the Royals away in the sixth inning. The left-hander has been fantastic this year, giving up more than four runs only twice since May 28. Duffy will face the Twins on Tuesday.
