If you're a contender looking for a credible inning-eater to round out your rotation, Sewell could trade Miles Mikolas (B3) and/or Clarke Schmidt (B2).  

If you're rebuilding and you want younger, unlimited SPers with potential upside, Sewell could trade Joey Wentz and/or Roansy Contreras.    

Looking for hitters- SS, 3B and 1B vs. both hands, OF vs righties, C vs lefties.
