Where should I rank Tom Wilhelmsen among closers?

Well, generally, he belongs in the mishmash tier of not-so-secure stoppers, which seems to have more members this year than many in recent memory. There's little track record to speak of here, despite his K talents. Expect a drop in control; he's still a bit wild and faltered a bit as last season wore on. Lefties still tag him a tad, as well.

Seattle also has some capable up-and-coming RPs behind him in Stephen Pryor, Carter Capps and Shawn Kelley. Still, it's Wilhelmsen's gig to lose, and the uncertainty surrounding him will negate most of the potential mixed money loss for employing him.
