Breaking: Should The Yankees Sign Vin Mazzaro?

Vin Mazzaro has been designated for assignment

It's not often that a relief pitcher the caliber of Vin Mazzaro becomes available, should the Yankees take advantage of this after he was designated for assignment? Mazzaro was the casualty of a deep bullpen and a 40 man roster crunch caused by first basemen Travis Ishikawa.

Mazzaro pitched to a 2.81 ERA last season in 71.2 IP and followed it up this spring with a 3.97 ERA in 11.1 IP.

I think the better question is would Mazzaro be better than David Phelps, Adam Warren, Vidal Nuno, or any of the other men we have in our bullpen not named Matt Thornton? I'm not so sure when you factor in the National League to American League transition. If this happened a month or two ago I think it is a foregone conclusion that Mazzaro is in pinstripes but now, I am not so sure.
