Frustrated with himself, Dontrelle Willis admitted that the Tigers might need to replace him with someone else in the rotation. "Today just was unacceptable," Willis said after Sunday's loss to the Pirates. "... I have to do something or somebody else is going to have to go out and help this team win. Skip's going to have to find someone else to do it." Willis is 0-3 with an 11.81 ERA in his last four starts, having walked 20 with eight strike outs in 16 innings.
