Jeremy Hefner
The New York Mets landed Juan Soto, and it just seems like everything got crazier. The starting pitching market is starting to heat up, and the team is going to be pushed to sign Sean Manae or look elsewhere.
If not, Manae, then who? Walker Buehler? Wait out Roki Sasaki?
Oh, and by the way, are the Mets going to be able to keep Pete Alonso?
While this is all happening, the Mets have yet to address their biggest need – the bullpen.
The bullpen was easily the Mets biggest weakness in 2024. It almost cost the team a chance of being competitive, and later, it almost cost them a chance of making the postseason.
By and large, the biggest disparity between the Mets and the Los Angeles Dodgers was their respective bullpens. The Dodgers rode theirs to a World Series, and they annihilated the Mets bullpen en route to winning.
As we know, the Mets are set at closer with Edwin Díaz. Now, they need to work on building the bridge to him.
Ryne Stanek served that role extremely well in the postseason. He had only allowed one earned over his first 5.2 innings, and he had that incredible 2.1 inning appearance in Game 5 of the NLCS picking up the win.
He’s won a World Series with the 2022 Houston Astros. Overall, he has a 2.89 postseason ERA going 4-0 with a 0.821 WHIP and a 9.3 K/9.
He’s a clutch postseason reliever. For Mets fans of old, it’s reminiscent of Dennis Cook. With the goal being to win the World Series, you want Stanek in your bullpen.
Now, the regular season has been a different story. Truth be told, he had a bad 2024, and that included his 6.06 ERA in 17 appearances with the Mets.
Still, he is a quality reliever with a career 114 ERA+. Also, as noted by Eno Sarris of The Athletic, Stanek is one of the best relievers available per that Stuff+ metric.
As noted by Fangraphs, Stuff+ “aims to capture the “nastiest” pitches in baseball, using a decision tree-based model to capture the nonlinear relationships that exist across release points, velocities, pitch movement, and more.” Read the article for more detail.
This is again where Jeremy Hefner factors into the equation. He’s long been a good pitching coach, but this past season was likely his best. He did wonders across the pitching staff. That included his work with Stanek.
Stanek has always had great stuff. He’s at his best in the big moments. He’s shown he can handle the stage. He’s everything the Mets need and want, and the team should make sure to keep him.
The Los Angeles Dodgers made the first big signing of the offseason by inking two time Cy Young winner Blake Snell to a five year deal. The deal was worth $182 million comprised of a $52 million signing bonus and deferred money.
With Snell, the perfect conditions were in place for things to get done this quickly:
- The Dodgers targeted Snell;
- The Dodgers will World Series contenders in 2025;
- The Dodgers have very deep pockets; and
- Snell lingered on the free agent market last offseason leading him to want to strike a quick deal this offseason.
For the Mets, Manae has vocalized his wanting to return to the Mets. The team and organization love him with teammates attending his wedding.
Manae finally seemed to hit that ceiling people thought he was capable of reaching. Part of that was changing his delivery to emulate Chris Sale. Another important factor was the analytics department coupled with Manae’s work with pitching coach Jeremy Hefner.
While not as long as Snell, Manae did have to wait until January to sign. He got a similar deal to Snell in both received a one year deal with a player option (both obviously declined their options).
Manea is a year older than Snell without the same historic success. Snell was the better of the two, but Manae was one of the better starters in the second half of the season.
Manae is not going to get a similar contract. That said, there should be an avenue for the Mets to strike early.
We know the team needs at least two starters. We don’t know where Corbin Burnes market will go. There are prevalent rumors Roki Sasaki going to the Dodgers is a fait accompli. There are other options with equal issues.
With Manae, you know there’s a pitcher who wants to be there. You know this is a pitcher who thrived in New York. He’s a pitcher who is everything the Mets could need or want.
The Mets need to move quickly to lock in Manae like the Dodgers did with Snell. They need to remove some uncertainty with their rotation. They need to move quick to sign Manae before someone else does.
The New York Mets gambled last season offering Luis Severino a one year $13 million contract. The deal could not have gone better for either side.
Severino made 31 starts for the Mets pitching 182 innings. He had a 101 ERA+ and a 4.21 FIP. He wasn’t the All-Star caliber pitcher he was with the New York Yankees before all the injuries, but he proved he could be durable enough to last a full season.
Severino stopped tipping his pitches. He occasionally flashed brilliance. His first two starts of the postseason were very good. The work with Driveline and Jeremy Hefner paid off, and Severino was entering free agency poised to truly cash in.
The Mets opted to gamble again and extended Severino a qualifying offer, which is $21.05 million. If he accepts, that’s a nice pay raise for Severino albeit with some risk.
Last offseason, with his injuries and top pitching, Severino needed a one year deal to rebuild his value. In 2024, he accomplished that and appeared in line for a multi-year deal.
That was at least until he was given a qualifying offer. With that, there are going to be teams who will not pursue Severino. Severino was good in 2024 but probably not good enough to justify losing a draft pick and/or international bonus pool money.
For Severino, that puts him in a bad spot. At 31, does he want to try to find a multi year deal in an already limited market? Would such a deal be worth passing on $21.05 million? Certainly, his AAV would look more like his 2024 salary than the QO.
For the Mets, they need starters, and Severino as a mid rotation guy would be perfect. This buys time for Christian Scott to return from Tommy John. It also buys time for prospects like Blade Tidwell and Brandon Sproat.
Mostly, it gets a key part of their rotation locked in as the Mets look to take the next step in 2025. Doing that while not over leveraging into the future is the best case scenario.
That’s Severino accepting the QO. It’s the best case scenario. It strengthens the 2025 rotation while mitigating the risk he doesn’t have any durability after pitching 100 more innings in a year.
Severino returning on a QO is a best case scenario. It would be a great start to the offseason. It’s the first step towards the Mets winning the 2025 World Series.
David Stearns made his first real foray into free agency signing RHP Luis Severino and INF Joey Wendle. These were curious moves to say the least.
Severino, 29, was dreadful last season, and he really hasn’t returned to his All-Star form after his 2020 Tommy John surgery. That said, there was hope in 2022.
In 2022, he was 7-3 with a 3.18 ERA, 1.000 WHIP, 2.6 BB/9, and a 9.9 K/9. Over his 19 starts, he had a 124 ERA+ and a 3.70 FIP.
Last year was a disaster. He had a 65 ERA+ and a 6.14 FIP. The caveat is he dealt with injuries which likely impacted his performance.
On that, Severino dealt with a lat strain in 2022 and an oblique in 2023. As we saw with Max Scherzer, the Mets struggled to deal with these types of pitcher injuries the past few years.
All that said, one year $13 million is a worthwhile gamble. That goes double with Jeremy Hefner as pitching coach and Stearns ability to build a pitching staff.
With Severino slotted for the back of the rotation, this makes sense. It makes more sense with the Mets needing to completely build a rotation.
Where things go awry is Wendle.
Wendle is coming off a year where he had a 47 wRC+ and a -3 OAA. He turns 34 in April, and unsurprisingly, he’s past his prime and in decline.
His wRC+ declined four straight years. The OAA dropped three straight years. He had seen his sprint speed drop three straight years before marginally rebounding last year.
Maybe he rebounds defensively, but he’s also going to be 34. He’s also literally slowing down If you’re betting on a defensive bounce back from a player, Luis Guillorme was a better bet.
However, the Mets non-tendered Guillorme. They then gave Wendle $2 million. It’s not a lot of money, but it’s a roster spot guaranteed to a player who should’ve been a minor league signing.
The hope is Wendle NEVER plays. The same would’ve been true if Guillorme stayed.
Ideally, Ronny Mauricio is the everyday second or third baseman. Jeff McNeil returns well from Tommy John. Brett Baty, Mark Vientos, or Mauricio are the answer at third.
Of course, it’s plausible all of the above fails. Also, let’s never speak of Francisco Lindor getting injured. Taking all that into account, Wendle is not the answer. He can never be the answer.
Whatever the case, it’s still early with plenty of difference making players available. We should wait to see the entire picture come to focus before fully judging even with this being an unspectacular and curious start.
In 2022, Jose Butto was pressed into action by the New York Mets, and the results weren’t good to say the least. In his one start, he allowed seven runs in four innings against the Philadelphia Phillies.
The start generated a number of reactions from fans. For the most part, the general reaction from Mets fans was that Butto was not a real prospect, and he was never going to make it.
Now, Butto seemed to solidify the case of the naysayers while pitching with Triple-A Syracuse this season. Over 19 starts, he was 3-7 with a 5.93 ERA. One of the key reasons was his 4.8 BB/9 and his inability to develop a third pitch.
However, something funny happened with Butto. With the trades of Max Scherzer and Justin Verlander along with the season (perhaps career) ending injury to Carlos Carrasco, Butto was pressed into action.
While Butto’s stats didn’t merit the opportunity, he got the opportunity because this was a lost season for the Mets. In many ways, it was for him as well. However, now, you cannot say the same for Butto. He got his chance, and he has put himself into the conversation for 2024.
Over his past three starts, Butto has pitched very well. While you may want to discount the start against the also ran Washington Nationals, the recent starts against the Arizona Diamondbacks and Miami Marlins deserve real attention with both teams fighting tooth-and-nail for the Wild Card.
https://x.com/PitchingNinja/status/1703906548550922527?s=20
He earned his first career win limiting the Diamondbacks to one run over five innings. He followed that up with an even more impressive performance. He struck out seven Marlins while limiting them one run over six innings.
Suddenly, there is talk about Butto being a part of the Mets rotation in 2024, or more likely, his being a part of the pitching staff.
What we are learning is his fastball/change-up will play at the Major League level. That combination was what powered a strong 2021 season, had him added to the 40 man roster (to protect him from the Rule 5 Draft), and put him on the Mets top prospect lists.
Now, that isn’t generating a big strikeout rate, but it is helping him avoid barrels. He’s holding opposing batters to a .274 SLG. Part of the reason is he has a high spin rate on his fastball. Another factor at play is his work with Jeremy Hefner, who has helped pitchers with similar stuff succeed with both the Mets and Minnesota Twins.
Now, there is nothing to say that Butto can repeat this success next year or even the rest of this season. Moreover, there is still a real question whether Butto can stick in the rotation or would need to move to the bullpen at the Major League level.
What we can say is the belief Butto was a prospect who could succeed in the majors was not in error. We are now seeing it. Having now seen it, we should be mindful that prospects take time and sometimes need to be beaten up and demoted before they succeed. That is true for Butto, and it will be true for many prospects which come after him.
On the surface, the New York Mets supposed plans to eat a bad contact to get a good player makes a lot of sense. After all, it’s what we say he Los Angeles Dodgers do when they first started their current run.
It’s also a great way to maximize Steve Cohen’s financial muscle. Go after teams at the mercy of a bad contract and see just how badly they need to get rid of the deal. For an owner like Cohen, that bad contract may be nothing more than a rounding error.
Who knows? Maybe the Mets can turn that bad contract into something too.
Take Steven Matz as an example. He’s had success in the past with the Mets. He’s got a good relationship with Jeremy Hefner. His splits against left-handed batters suggest he could be an effective left-handed reliever/long man.
Who knows how much the St. Louis Cardinals want to me rid of him. Do they give up a decent prospect? Maybe a decent reliever? It’s worth gauging interest.
Going back to the Dodgers, the plan worked beautifully because Andrew Friedman was in charge. Friedman is among the best there is.
As for the Mets, they have Billy Eppler. He’s the same GM who couldn’t win with Mike Trout and Shohei Ohtani. More recently, he’s the one responsible for the current Mets roster issues.
To execute trades like this, you have to trust your current GM. Looking at Eppler’s Mets trade history, the only trade that hasn’t proven to be a debacle has been the Chris Bassitt trade.
Based on that trading history, you really can’t trust Eppler with executing trades of this nature. He is going to be inclined to attach a prospect with real value for what will amount to little more than a salary/contact dump.
The obvious retort is he is the GM, and you need to be able to trust him to make these (or any) trades. However, Eppler has a long history as a GM now, and nothing there suggests he can or should be trusted.
Put another way, Eppler should not be the GM. In fact, he never should have been hired. It’s better to not let him screw things up more and reset in the offseason. After all, Eppler has shown he can make any situation worse.
We knew entering the 2023 season the New York Mets rotation was old, and by extension, more susceptible to injury. We were just hoping that we could at least get to Opening Day, or at least the start of the World Baseball Classic, before the team had to face a starting pitcher injury.
As it turns out, José Quintana has a broken rib. As a result, he had to pull out of the World Baseball Classic, and he is almost a lock to be out on Opening Day. In reality, he may be out much longer than that. Of course, the hope is he misses as few starts as possible.
With Quintana out, it presents an opportunity for David Peterson. In some ways, this is really his first real chance to prove himself as a Major League starter.
Yes, he was a surprise add to the Mets 2020 roster during the pandemic shortened and impacted season. He performed better than anticipated. On the strength of that season, he was given a starting job at the outset of 2021. Unfortunately, he predictably failed, and his career has been in limbo ever since.
Since that time, Peterson has developed as a promising starting pitcher. We see he has excellent arm extension on his pitches. He has also developed into a pitcher who generates a high amount of strikeouts. His slider has become an excellent weapon, one that was one of the best in the majors last season.
Peterson has done all he could do in the minors. He now needs to be in the majors working on his craft with Jeremy Hefner. As an aside here, Hefner works extremely well with sinker/slider pitchers like Peterson. Hefner working with Peterson could very well have Peterson reaching another level of his game and/or becoming more consistent.
Peterson has earned this chance. He needs to be in this position. Now, it appears he is getting that chance to be a part of the Mets rotation. He now has to pitch so well the Mets simply cannot remove him from the rotation when everyone is healthy.
The New York Mets are still looking to build their bullpen, and the one spot they haven’t quite addressed is the one now vacated by Trevor Williams. Williams held down the role once held by Seth Lugo. Like Williams, Lugo left via free agency, and the Mets really do not have a long man in their bullpen.
In many ways, the long man role is one that needs to be manufactured. it is for a starter who can’t quite start but needs to be good enough to fill-in that role on necessity. It also needs to be a reliever who is not quite dominant because those dominant relievers are better suited and more needed in the later innings of games.
Often times, the long man is just found out of necessity. For example, Williams had no options remaining. He was put in the bullpen where he was terrific. We have seen the Mets thrive with long men options in the past like Williams, Pat Mahomes, Carlos Torres, and Sean Gilmartin.
This is a role which should not go to David Peterson or Tylor Megill, each of whom the Mets should be developing. Rather, the Mets need to sign a free agent for this role, and surveying the landscape, it would seem Dylan Bundy is well suited for this role.
Bundy, 30, was once a big time prospect being selected fourth overall by the Baltimore Orioles in the 2011 draft. Coincidentally, he would play as a rookie and young player under Buck Showalter, and like we see with Tommy Hunter and Mychal Givens, the Mets have liked bringing back some of Showalter’s old Orioles pitchers.
Looking at Bundy, his only good year as a starter was the pandemic shortened season of 2020. With a career 92 ERA+ and 4.68 FIP, it is really time to admit Bundy isn’t a viable starting pitcher in the leagues. That is moreso the case for a pitcher who has been at a 77 ERA+ and 5.00 FIP over the past two seasons.
Going to Baseball Savant, Bundy does a few things very well. First, he has excellent control. Second, he gets good spin on his fastball. Overall, he doesn’t walk batters, but when batters make contact, they really create damage.
Remember, by signing Bundy you’re not looking for a shutdown reliever. Rather, the goal is to find a reliever who can just eat innings. They need someone out there who can save the bullpen. A pitcher who doesn’t walk batters and is accustomed to pitch more than 1-2 innings is exactly who you want.
In his career, Bundy is at his best the first time through the lineup. The first time through he limits batters to a .239/.298/.432 batting line. That’s exactly what the Mets want. Rather, it’s what they need. They need a pitcher who can handle the first time through the order exceptionally well and who can eat innings to save the bullpen.
This is what Williams was. Of note, Jeremy Hefner worked well with Williams to adapt to this role. Chances are, he and Showalter can do the same with Bundy. As a result, the Mets should sign Bundy to take over the long reliever role.
Back in 2015, the New York Mets made the mistake of trading Michael Fulmer to acquire Yoenis Cespedes. No, it was not a mistake to obtain Cespedes, but rather, Fulmer was far too high a price to pay. As it would turn out, the Mets needed starting pitching the ensuing two seasons where Fulmer was winning Rookie of the Year and being named an All-Star.
Well, from there, Fulmer had some injury prone years and moved to the bullpen. For his part, Cespedes needed double heel surgery, and then, he would have an incident falling off his horse or something with a feral hog during his rehab. The details are still murky.
Regardless, the Detroit Tigers received a 12.2 WAR out of Fulmer and a prospect at the trade deadline. The Mets received an epic run from Cespedes amounting to a 2.1 WAR and not postseason production at the plate past Game 3 of the NLDS. In essence, the Mets made a win-now trade and didn’t win.
Fast-forward to 2023, and Fulmer is a free agent while Cespedes is trying to get back into the majors. The Mets are also looking to build a bullpen which can get them their first World Series since 1986. It already looks formidable with the following relievers in place:
There are other pitchers in the mix, but these are the relievers who are guaranteed. With five starters, that leaves up to four more relievers who can be added. The presumption is at least two of Joey Lucchesi, Tylor Megill, and David Peterson will start the season in Triple-A to provide organizational starting pitching depth.
That probably leaves pitchers like Jeff Brigham and John Curtiss on more of a solid footing to make the Opening Day bullpen than they probably should. Even with those names likely to make the bullpen, the Mets are still at least one arm short.
Fulmer, 29, would be an excellent fit. As a reliever, he has a 128 ERA+. As per Baseball Savant, he does an exceptional job limiting hard contact and barrels. We’ve also seen Jeremy Hefner work well with pitchers how have a similar repertoire. All told, he probably remains the best arm remaining on the market.
While we are very confident in this Mets roster, they probably remain an arm short in the bullpen. Fulmer would go a long way to resolving that issue and make this Mets team even better. All this time later, the Mets now need to sign Fulmer instead of trading him to try to help put this Mets team over the top.
Right now, the New York Mets are rumored to be listening to offers for Carlos Carrasco. This makes sense because the Mets should listen to offers on all of their players and make deals if it improves the team. That should go without saying.
There is also the matter of clearing up payroll to permit the Mets to address their bullpen, outfield depth, and find a better solution than Daniel Vogelbach and Darin Ruf at DH. Mostly, the Mets would be better served by having David Peterson in the rotation.
Peterson, 27, was the Mets 2017 first round pick (20th overall) out of the University of Oregon. At his age, this is exactly the time you would be expecting his career to take off, but frankly, to date, it has not gotten started. There are several reasons why that has happened.
After a promising 2020 rookie year in the pandemic shortened season, he predictably struggled in 2021 before succumbing to a shoulder injury. This would have the Mets under Steve Cohen bypass him as they looked to build an elite rotation designed to win the World Series. Despite that, Peterson would be needed, and he would have his moments.
Overall, as a starter, Peterson was 6-5 with a 3.86 ERA, 1.341 WHIP, 4.1 BB/9, and a 10.9 K/9. He would also average 4.2 innings per start. The caveat there was in two September starts, he threw four innings total over two horrific starts. This came at a time the Mets were working to move him to the bullpen for the postseason. Without those two starts, he averaged 5+ innings per start.
No, these aren’t earth shattering numbers, and yes, the walks/control were an issue. However, there are some caveats with these numbers. He was bounced back-and-forth from the rotation and bullpen AND between the majors and Triple-A. That takes its toll on a player. Notably, Peterson did perform better in the majors than in Triple-A.
Another factor is Peterson did not get to really work with Jeremy Hefner the way the rest of the Mets pitching staff did. Notably, we did see Hefner help hone pitchers mechanics and work on their control. This was most notable with the work Hefner did with Edwin Díaz to get him to repeat his landing spot on the mound. As a result, we not only saw the best we’ve seen from the closer, but we also saw Díaz go from a 4.9 BB/9 in 2020 to a 2.6 last season.
Arguably, if Peterson is going to take that next step, he is going to need Major League coaching, be surrounded by pitchers like Max Scherzer and Justin Verlander for a full season, and really, he is going to need a chance.
Looking at the data, he is worth that chance. Per Baseball Savant, Peterson generates excellent extension, and he has a very good whiff%. That is shown with Peterson striking out 27.8% of the batters he faced last season, which is excellent. Part of the reason for that is despite lower fastball velocity and spin (which should be expected with a sinker) is Peterson’s excellent slider numbers.
Highest single-season slider whiff% by a lefty pitcher in the Statcast era (min. 250 sliders swung at):
Andrew Miller: 54.7% ('15)
Amir Garrett: 53.7% ('19)
Patrick Corbin: 53.1% ('18)
Corbin: 51.4% ('19)
Robbie Ray: 49.5% ('17)
Corbin: 49% ('16)
DAVID PETERSON: 47.9% ('22) pic.twitter.com/vSAd5nAdLQ— Mathew Brownstein (@MBrownstein89) December 1, 2022
It is genuinely a strikeout pitch. Batters whiffed 47.9% of the time against the pitch. In and of itself, it is worth investing in that pitch to see what more the Mets could be getting out of Peterson. That slider is a hidden gem on this Mets staff, and they need to see it in the majors instead of Triple-A.
Put another way, Peterson still has a lot of upside. In many ways, he is still raw and needs more coaching and opportunities. For an older Mets rotation, they actually need Peterson’s upside. They need the younger starter who can surprise and have a good year. Somehow, some way, the Mets just need to get Peterson into the rotation and watch him take that next step because that next step could help the Mets win the World Series.
