Even in AL-only leagues the only reason Veras is worth owning is that he has the closer job. Is owning Veras more valuable for you than owning a set-up guy from another team? I should think so...but it might be close...one has to at least think about it.
You can upgrade at another position and throw Veras in the deal, this would open up a roster spot for you to prospect.
I'm assuming that guys like Madson and Valverde are owned in your league. They should be.
I wouldn't waste a roster sport on handcuffing the Astros' closer situation. I would prefer to use that spot to pick up a potential breakout hitter or pitcher.
Oswaldo Arcia anyone? http://razzball.com/chooch-ooh/
