Top Fantasy Pitchers

There's several Mets' pitchers on the FantasySP ADP list so far.

Leading the way is closer Edwin Diaz, who is going around pick 60.83 on average. 

Starter Kodai Senga is going at pick 143.06, while Sean Manaea is at pick 163.82.  

Diaz had some ups and downs in 2024. He returned to the mound after missing all of 2023.

In 54 appearances, Diaz had a 6-4 record and 3.52 earned run average. He also collected 84 strikeouts across 53 2/3 innings and had 20 saves.

Diaz was not all that close to being a top-10 fantasy reliever last season, but is being drafted fourth among closers so far, with the two guys after him going within six picks.

I personally have Diaz sixth among fantasy closers in my 2025 redraft rankings, but Diaz is also on my list of fantasy draft bust candidates. I think his ADP is too high, and would be much more comfortable taking Diaz a round or more later.

I think at his current ADP, there's not a ton of room for Diaz to exceed expectations, while having a much higher chance of being a bust. Regardless of if Diaz is my first or second fantasy closer for 2025, I'd want to make sure I had other options on my team in case he pitches similarly to last year.

Senga only pitched in one game in 2024, but he appears to be healthy and ready to go for 2025.

In 29 starts in his first MLB season in 2023, Senga had a 2.98 ERA and 12-7 record. He struck out 202 batters over 166 1/3 innings.

There's definitely some durability concerns to worry about after last year, but some really good upside too. Based on where his ADP is at now, I like the idea of taking a chance on Senga, as long as his ADP mark doesn't rise multiple rounds. 

Taking him to help fill out your rotation doesn't take on a ton of risk, and there's a chance he's a keeper all season. The upside outweighs the downsides here, in my opinion.

Manaea's ADP is trending down because of an injury.

He made 32 starts for New York last season, going 12-6 with a 3.47 ERA. He struck out 184 batters over 181 2/3 innings.

Manaea looks like a big-time draft steal at his current ADP, but if he's going to miss part, or all, of April, which reports are suggesting, it makes sense that he's trending down now. 

When healthy, Manaea is a keeper in all fantasy leagues, but unless you have an IR spot to put him in at the start of the season, it doesn't make a ton of sense to waste a roster spot on Manaea. The deeper the league, the more sense it makes to stash Manaea. He'll be a hot waiver wire addition when nearing a return, so be sure to be locked into Mets' news to know when that is.

Other Starting Options

There will be other Mets' pitchers who are good fantasy assets in 2025, but at the start of the season, the remaining options are deep-league targets at best.

According to FanGraphs, David Peterson, Clay Holmes, Paul Blackburn and Griffin Canning are projected to fill out the starting rotation behind Senga. Manaea is joined on the injury list by Frankie Montas and Christian Scott. 

Montas would likely have gone near the end of standard league drafts, or at least been in the picture, if not for his injury. He's not expected to pitch until May.

In stints with the Brewers and Reds last season, Montas made 30 starts, had a 7-11 record and posted a 4.84 ERA. He struck out 148 batters over 150 2/3 innings. Instead of having to worry about wondering if you should draft him or not, the injury should make him a sure streaming option when he's healthy - he's a good deep-league option though and should be kept in most of those leagues.

Scott isn't expected to pitch in 2025, but FantasySP will cover him later in the season if he's able to log a few innings.

Peterson made 21 starts for the Mets in 2024, going 10-3 with a 2.90 ERA. He struck out 101 batters over 121 innings. 

He set a new career best in ERA, and I expect some regression this coming season. Because of low strikeout numbers, Peterson isn't a big-time standard league option, but he'd be a streamer if he can pitch close to last year's ERA. Peterson should be rostered in most deeper leagues to begin the season.

Holmes is making the switch to be a starter (instead of a reliever) with his new New York team. In his seven-year career, Holmes has a 3.71 ERA across 311 appearances and 337 1/3 innings. He averages 9.7 strikeouts and 4.1 walks per nine innings.

It's always a challenge to guess how a reliever might fare in the rotation. I don't expect Holmes to work 6+ innings every start, and a little regression in his career ERA and strikeout marks could be coming, so he's just a deep-league option in my eyes. He could maybe earn some spot starts against weak-hitting teams if he's pitching well, but I'd temper expectations for him.

Blackburn made 14 starts last season, with five coming for the Mets. He went 5-4 with a 4.66 ERA, striking out 59 batters over 75 1/3 innings.

He's just a deep-league option to begin the season, but could also be a standard league streamer. I'd guess Blackburn loses his rotation spot once Manaea and Montas are back.

Canning probably loses his rotation spot when one of those starters comes back. In 32 games and 31 starts with the Angels last season, Canning went 6-13 with a 5.19 ERA and 130 punchouts over 171 2/3 innings.

He's probably going to top out as a deep-league streaming option early in the season, but injuries could keep him involved, so don't write him off.

Setting up Diaz might be A.J. Minter and Jose Butto. Reed Garrett, Ryne Stanek, Danny Young and Dedniel Nunez are the other projected bullpen arms, while Sean Reid-Foley is the projected long reliever to open the season. Drew Smith is another pen arm who is expected to miss the entire season.

Unless Diaz is injured, it will be hard for Minter and Butto to be big-time fantasy assets. In some deep leagues, relievers with low ERAs and big strikeout numbers could be usable. Garrett is the guy I'd keep an eye on after his big 2024 season.

Top Prospects

Brandon Sproat (No. 46) is the lone New York pitching prospect on the MLB's top-100 prospect list. 

He has just one minor league season under his belt, but is expected to still debut in 2025. Sproat had a 3.40 ERA and 131 strikeouts over 116 1/3 minor league innings in 2024.

Blade Tidwell and Dom Hamel are a couple other of the team's top-30 prospects from the end of last season who could factor in this season, although it might take several injuries.

Tidwell has a 4.14 ERA across 247 2/3 minor league innings in three seasons. He has 285 strikeouts and a .221 average against him, so there's reasons to keep tabs on him.

Hamel has a 4.61 ERA across 370 2/3 minor league innings in four seasons. He has 436 strikeouts and a .238 average against him.

New York is pretty top-heavy when it comes to its pitching, but you just never know who might be needed during the course of a 162-game regular season.
