1. Emmanuel Clase

Clase was the No. 1 fantasy closer last season, and I think he maintains that spot for the 2025 season.

Clase had a ridiculous 0.61 earned run average last season, while going 4-2 and racking up 47 saves. He struck out 66 batters across 74 1/3 innings.

Clase is a stud, and the Guardians should remain a good team for this coming season. Cleveland will be in a number of tight games, and even if he regresses a bit, I see Clase finishing atop the position.

2. Devin Williams

Williams moved from the Brewers to the Yankees this offseason. I think the Yankees are a better team overall, but I’m not sure how much the move will actually help Williams’ fantasy outlook.

The Brewers played in a lot of close games, and while he might get a similar amount of save chances on a Yankees’ team that wins a lot, I actually think Williams’ fantasy value was better in Milwaukee.

In 22 games, Williams posted a 1.25 ERA, a 1-0 record and 14 saves last season. He struck out 38 batters over 21 2/3 innings. Once he settles in with New York, he should be one of the top fantasy closers, but I don’t think he’ll overtake Clase.

3. Josh Hader

Hader is my No. 3 guy after regressing a bit in 2024. 

He went 8-8 with a 3.80 ERA and 34 saves across 71 games pitched. Hader struck out 105 batters over 71 frames.

I think Hader gets back on track with his ERA this season, and if he even meets his 2.70 career mark, he’ll contend for the top fantasy closer spot. His big strikeout numbers are going to put him in the hunt, at the very least.

4. Mason Miller

Miller is probably my favorite fantasy closer, but playing for the Athletics knocks him down a few pegs.

He went 2-2 with a 2.49 ERA across 55 games last season. Miller earned 28 saves and struck out 104 batters over 65 innings.

If the Athletics were actually good, or even competitive, Miller would probably easily be the top fantasy closer. But without a bunch of saves, Miller is dependent on big strikeout numbers and a very low ERA. The only way I see him finishing higher than this is if he gets traded.

5. Ryan Helsley

Helsley was the No. 2 fantasy closer last season, but I don’t think he’ll be nearly as good in 2025.

In 65 games, Helsely went 7-4, with 49 saves and a 2.04 ERA. He struck out 79 batters over 66 1/3 innings. Helsley has a career 2.63 ERA and had never pitched over 54 games in a season, so I expect him to regress a bit in his numbers this season (plus, seven wins likely isn’t happening again).

I think Helsley is a bit overrated this season, and that he’s going too early in fantasy drafts. If he falls a couple rounds, then I have no issue drafting him.

6. Edwin Diaz

Diaz had an up-and-down 2024 season, but was most importantly able to pitch in 54 games and get through 53 2/3 innings. After not pitching in 2023, Diaz should have knocked the rust off and be ready for an even better 2025 season.

In 2024, he went 6-4, with 20 saves and 84 strikeouts. He has a career 3.00 ERA and averages about a strikeout-and-a-half per inning.

He could end up finishing way higher than I have him ranked, but with the few concerns I have with him, I’m most comfortable ranking him sixth. 

7. Raisel Iglesias

Iglesias was great in 2024, and he did it rather quietly.

In 66 games and 69 1/3 innings, Iglesias went 6-2 with 34 saves. He had a 1.95 ERA and struck out 68 batters.

He should close again for a Braves’ team looking to bounce back. Iglesias’ ERA might regress a bit, but he should be in line for 30+ saves and a good amount of strikeouts and innings pitched. He’s a bit of a sleeper in my mind, especially if you don’t have to spend a super early pick on him.

8. Robert Suarez

Suarez broke out in a big way in 2024 and now is viewed as the Padres’ closer for the near future.

He went 9-3 with a 2.77 ERA across 65 games last season. Suarez had 59 strikeouts across 65 innings pitched and picked up 36 saves.

He should be in line for another big fantasy season, but with only one big season under his belt, I’m not comfortable taking him any higher than this. I don’t see him winning nine games again, so unless his ERA drops, he earns more saves or he strikes out more batters, I think he regresses as a fantasy asset.

9. Andres Munoz

Munoz was a bit inconsistent in 2024, but his numbers overall look very solid.

In 60 games, Munoz was 3-7 and had a 2.12 ERA. He struck out 77 batters over 59 1/3 innings, while earning 22 saves.

Munoz could be a major draft steal if he produces a similar ERA and strikeout numbers, or just getting closer to 30 saves. I’d definitely have Munoz on my radar later in drafts, especially if I missed out on some of the top-end talent. 

10. Jhoan Duran

Duran had a rough go of things in 2024, but now healthy, most people are expecting a bounceback season from him.

In 58 games and 54 1/3 innings last season, Duran went 6-9 with a 3.64 ERA. He struck out 66 batters and had 23 saves.

Duran looks to be the team’s closer going into 2025, but Griffin Jax is also coming off a big season and could steal the job away if Duran struggles in spring training or at some point during the season. Last season wasn’t great for Duran, but it’s hard to ignore his numbers from his first two seasons. I’m banking on Duran returning closer to those two seasons, and if he does, he’s another possible big-time draft steal.

Honorable Mentions

There’s a number of closers who could crack the top 10 by the end of the season.

The pitchers closest to making my top 10 were Felix Bautista, Lucas Erceg, Kirby Yates and Tanner Scott.

Some other intriguing names to me are: Kyle Finnegan, Alexis Diaz, Kenley Jansen, Ryan Walker, Jordan Romano, Trevor Megill, Pete Fairbanks, David Bednar and Porter Hodge.

Of course, there’s a handful of free agents in that group, and they could jump into my top 10 if they end up signing with a contender. This is probably the top-10 list that could change the most between now and the start of the season.
