Duffy gave up six runs over 5.2 innings on nine hits with one walk and two strikeouts to fall to 1-3 in Friday's loss to Toronto.
It was Duffy's first poor outing in five starts since being recalled from Triple-A. He had just two strikeouts after 23 in his prior 24.3 innings. Hopefully it was just an off night against one of the league's better offenses.
