there's no way they'd DFA rusch. zambrano could get hurt in his next start or guzman/hill could go completely in the toilet. if you dump rusch, then who do you go to? ryu? walrond? marmol? i'd send aardsma down, and bring up wuertz just so you have a fresh arm out there for the next couple days. then when it comes times for rusch's next start, you send down whoever's pitching the worst b/w wuertz and novoa and bring up hill for the start.
