I'd take Contreras over Moss. Moss is having an awful spring and may not have a rotation spot with Reuter, Hernandez, Jensen, Schmidt and Ainsworth. Contreras (may not have a rotation spot either - but t least he's fighting Wells and Pettite) may just surprise some people. Just a feeling, but I'd go Jose.
