Wagner as a sleeper??
He didn't close all the games last year, but then niether did anyone else in baseball. He is a bona fide stud closer
As to lower tier closers, Williamson seems locked in to the job, so he is a good choice, and maybe looper. Watch for Vizcaino in Milwaukee, and German in Detroit to be factors, and don't count on stewart being the closer in Montreal for long.
I watched Embree pitch alot at Pac Bell, and I wouldn't draft him. He won't be able to handle the pressure of closing. Great middle man, not a closer.
Watch the waiver wire, pay attention, and be prepared to gamble on guys who might get a shot.
