Travis Blackley struggled in a spot start against the White Sox on Saturday, allowing five runs on six hits over five frames. Blackley walked one and piled up six strikeouts. Kevin Youkilis smashed a two-run homer in the fifth inning, pulling the Sox to within 6-5 and capping the damage against him. While Blackley has had some success in the rotation this season, he'll return to a long relief role in the bullpen as the A's are stocked with depth in the rotation and still have Brett Anderson and A.J. Griffin likely to return in the coming weeks.
