1. Brian Wilson
Non-tendered by the Giants who would have had to offer him at least $6.8 million, Wilson has gotten interest from a number of teams but is not yet ready to accept a minor league deal. He'll have to prove healthy before anyone even thinks of letting him close, but he's worth a flier.
2. Rich Hill
Also a non-tender casualty, Hill spent time on the DL last season, but was a solid option when healthy with a 1.82 ERA and 9.6 K/9 in 19.2 innings of work over 25 appearances. The fact that he's left-handed only adds to his value, and he should be able to win a job somewhere this spring.
3. Francisco Rodriguez
Rodriguez is not the pitcher he once was, but he is still a solid workhorse setup man who should strike out a batter an inning and is capable of closing in a pinch. With 294 saves and 2.70 ERA, his career track record speaks for itself.
4. Jose Valverde
Chased out of Detroit after struggling mightily as their closer last season, Valverde will likely have to settle for being a setup man at best this coming season. I think a return to Houston, where he closed for two years, makes sense as he'd provide an insurance option to unproven closer Jose Veras.
