Stammen needs to stay working out as a starter in AAA. The Nationals need Stammen as a back up starter in AAA because if someone else goes down the Nats don't have too many more choices after Balester is up. JD Martin / Stammen possibly Estrada. Collin Balester is ready now with 3.98 era and 3 wins in a row. He has Major league experience and is ready to get it going on the Bigs!!!
