Positional rankings | Top 300 | Draft Prep Guide!

In deeper leagues, and even in standard Rotisserie formats, the sad truth is that not everyone can get as many closers as they like. In AL- and NL-only leagues, you might be lucky just to get one reliable saves source.

That's how the likes of Wade Davis and Tony Watson have made it into our average draft position rankings (ADP), even though both are firmly ensconced in setup roles. In leagues where closers are scarce, it helps to know which potential closers to target. They're often more worthy of a late-round pick than starting pitchers, as you can often find serviceable starters on waivers in most formats.

I've compiled my top 10 list of closers-in-waiting for you to peruse, borrow, or critique. As good as they are, I've left Davis and Watson off this list, as the closers they set up (Greg Holland and Mark Melancon) are among the best in Fantasy. I have also excluded unsettled or committee situations, since it's unclear who is closing and who is waiting. There are some worthy targets in those situations, to be sure, and Andrew Miller and Brad Boxberger in particular would be at the top of the list if we knew for sure they weren't going to be closing games in early April.

Finally, I've excluded injured closers who are just waiting to get healthy to reclaim their roles. Sorry, Kenley Jansen and Sean Doolittle, but you're more closers-in-recovery than closers-in-waiting.

Enough with the rules of this game; let's count 'em down.

10. Miguel Castro, Blue Jays: The 20-year-old has yet to pitch above Advanced Class A, but he's drawing attention with a great spring. Later in the season, he could provide manager John Gibbons with an alternative if he wants to move lefty Brett Cecil back into a setup role.

9. Adam Ottavino, Rockies: Ottavino has one of the less-imposing roadblocks in the form of LaTroy Hawkins, but there are few pitchers I would completely trust in Colorado's closer role.

8. Edward Mujica, Red Sox: With a true opportunity, I think Mujica would be a fine Fantasy closer. However, Koji Uehara just might stay healthy once he's ready to return. If he doesn't, there's also Alexi Ogando to potentially take away save opportunities.

7. Kevin Quackenbush, Padres: He's another perfectly good closer candidate. I'm just not sure he will get much of a chance at a promotion unless Joaquin Benoit is dealt.

6. Evan Marshall, Diamondbacks: I have a strong suspicion that Addision Reed won't last the year as Arizona's closer, and I like Marshall's chances of replacing him better than Brad Ziegler's.

5. Jonathan Broxton, Brewers: Broxton was effective in 2014 and enjoyed a late season surge in strikeouts. Francisco Rodriguez was just not very good in the second half last year, and I'm not at all convinced he's still fit for the closer's role.

4. Bobby Parnell, Mets: He's on the fringes of being a closer-in-recovery, but there's enough ambiguity about the Mets' closer situation that he qualifies for this list. Manager Terry Collins seems to like him enough that I could see him supplanting Jenrry Mejia at some point.

3. Jordan Walden, Cardinals: Walden's got closer stuff, and if Trevor Rosenthal can't make friends with the strike zone in the early going, I could see manager Mike Matheny handing the keys to the ninth inning to his new setup man.

2. Joakim Soria, Tigers: Anyone setting up for Joe Nathan would seem to have a good chance to close eventually, and Soria has been an exceptional closer in the past. He certainly looked the part for most of last season.

1. Ken Giles, Phillies: It has to be just a matter of time before Jonathan Papelbon gets traded, and then the closer's job will assuredly belong to Giles. As a rookie last season, he had no problem thwarting opponents to the tune of a .450 OPS, and he did so in a setup role. It was a pretty impressive feat, and it bodes well for him having success when he inherits Papelbon's job.
