Aquino in a regular 5x5 league... well any closer is worth having I suppose. But I wouldn't pick him over anybody of value. he's at the bottom of the closer pile with Chad Cordero, so I guess it depends on the type of league, how the owners draft, who else is left when you're thinking of taking him. But overall - yes, I think he should be owned in a 12 team league. I'd give him the boot the second he loses favour with the manager though (whoever their manager is come opening day, LOL).
