Danny Duffy allowed one hit over six innings as the Royals beat the A's 3-0 in a rain-shortened game Tuesday. The game was delayed in the top of the eighth and eventually called. Duffy excelled in this one, striking out eight. A Cliff Pennington double was Oakland's only hit of the game. Duffy, though, did walk four, pushing his pitch count up to 103 over six innings. He has the stuff to put together more outings like this one, but until the command comes, he figures to be inconsistent.
