'I don't know how serious it is,' said skipper Jim Riggleman of the injury. 'Hopefully, he misses just a turn, but that's a tough area.' Washburn did not show any signs of discomfort in this last outing, when he tossed 6 2/3 scoreless innings against the Indians on Sunday. The injury forces a shift in Seattle's rotation, as Morrow will make his big league starting debut Friday, followed by Ryan Rowland-Smith on Saturday and Carlos Silva on Sunday.
