Jose Mesa is the best available and then Bob Wickman,
Mike Adams, Justin Speier, Chin-Hui Tsao, Jeremy Affeldt and Ryan Dempster in no particular order. And as Lumberjacks mentioned, Aquino and Valverde.
If you are desperate for closers, then they're all possibly worth drafting but Mesa is the safest option by far.
