The Mets need pitching, but they don't need another headache, That eliminates Dontrelle Willis (1-2, 4.98) who was designated for assignment by the Tigers. The dynamic young picther of a few years ago is gone  and Willis needs time in the minor leagues to reclaim whatever form will be tolerated by a big league team. The Mets already have a Dontrelle Willis on their staff. His name is Oliver Perez (0-3, 6.25).
