Freddy Peralta’s Trade Value Hasn't Changed Much Despite Seemingly Disastrous Mets Tenure

The New York Mets’ January acquisition of Freddy Peralta was supposed to be the beginning of a long and fruitful partnership. In the final year of an incredibly team-friendly deal, Milwaukee dealt their top-of-the-rotation force to the Mets for Brandon Sproat and Jett Williams, both top-100 prospects. The expectation in Queens was that the Mets would compete, Peralta would shove, and extension talks would be a breeze. Well, you know what they say about the best-laid plans of mice and the Mets. 

Neither team nor player have had the season they envisioned. The Mets are poised to be sellers at the trade deadline, and Peralta, quite candidly, mused that he had thrown his last pitch for the franchise. While January plans have a way of melting in the July heat, New York should still be optimistic about landing a sizable return for Peralta, should they trade him. 

First and foremost, the 2026 trade deadline is shaping up to be a sellers' market. According to FanGraphs playoff projections, 21 teams have a 10% or better playoff odds, and 20 teams, if you round up for the Padres at 14.7%, are at 15% and above. That’s nearly two-thirds of the league, and many of the de facto eliminated teams have next to no interesting pitching to offer (hello, Athletics and Rockies). 

Second, with the Tigers surging, Tarik Skubal may never hit the trade block, which means Peralta could end up being the most accomplished starter to move. Despite a lackluster ERA (4.99) this season, Peralta has been incredibly durable (30-plus starts 2023-2025), has a very recent track record of success (3.40 ERA 2023-2025), is only making $8 million this season, and his xERA of 3.84 is much more in line with his career ERA of 3.74. 

Nearly every team could afford to add Peralta’s salary, and just about every contender could use another pitcher who can start a playoff game. While the bidding for the 30-year-old wouldn’t incite the frenzy a Skubal sweepstakes would, if he’s the best or second-best starting pitcher on the market, the Mets will field multiple competitive offers. 

And solid starting pitching, even rentals, almost always lands real prospects. Using the past two trade deadlines as a proxy, there have been about eight trades for either a starting pitcher with a similarly sterling track record as Peralta or who was in the midst of a strong season.

From this group of eight trades, 16 prospects of note (40-grade on 80-point scale or better) were secured, with three 50-grade prospects moved, and on average, teams acquired two 45-grade prospects. Considering the Mets had to part with two 50-grade prospects for a full season of Peralta, likely landing two 45-grade or one 50-grade farmhand for less than half a season of his services indicates his value hasn’t diminished as precipitously as his ERA has ballooned.

On top of the prospects that ended up being moved, solid major-league contributors (2026 All-Star Miguel Vargas went to Chicago in the Erick Fedde trade), lottery ticket teenage arms, and cash were liberally sprinkled throughout. None of these were blockbusters, but organizations have become much more tightfisted with their top prospects when acquiring rentals. 

Any team that makes a serious run for Peralta will have to be confident in two things. First, that his ERA is largely a result of bad luck (.319 BABIP and 68.4% Left-on-Base%), and second, that they can get his pitches back to where they were in Milwaukee. 

As for the first part of the equation, just about every front office will point to to explain away his 4.99 ERA. Peralta has a career BABIP of .271 and LOB% of 74.8%, and even with some decline, he hasn’t suddenly become the most hittable pitcher in the league. This confluence of bad luck will keep his market relatively stable, as most teams should view his floor as at least a backend starter who will take the bump every fifth day and pitch to around a 4.00 ERA. That’s not a splashy acquisition, but for any team with question marks in their rotation, it can be the difference between making or missing the playoffs. 

The second part of the equation is where a team could end up convincing themselves that they’re landing a real front-of-the-rotation force. This season, Peralta’s strikeout percentage has slumped to a career low 22.1%, while his walk rate (9.4%) is almost a dead ringer for his career average (9.3%). Usually a decline in strikeouts comes from diminished stuff, which has been the case for Peralta, but not in the hugely concerning way. 

His average four-seam velocity of 94.2 MPH is down a bit from his 94.8 MPH average in 2025, but he was a wildly effective pitcher in 2024 and 2023 when the pitch averaged 94.4 and 94.3 MPH, respectively. His secondaries have similarly lost a bit of velocity, outside of his curve, which has sped up, but they’re all thrown in velocity bands where he has had tons of success. Clearly, arm strength isn’t the primary reason his stuff has fallen off. 

Two things have changed dramatically this season for Peralta, and it’s likely why he has lost some swing and miss. He has drastically lowered his arm angle, while also losing a significant amount of extension. 

Fluctuations in arm angle and extension are just the reality of not being a robot, but 2026 sticks out like a sore thumb. More extension is generally better, with a few notable exceptions. Arm angle, on the other hand, will impact pitch shape and approach angle, which may or may not end up being a positive, and in Peralta’s case, it has largely been a flop. His fastball has gone from possessing outlier shape to having much more average movement, and it has also seen his breaking ball shape converge. 

The reason why Peralta made these changes is uncertain. It might have been a conscious decision to try and chase better pitch characteristics. It could be a breakdown in mechanics, or he could be pitching through a minor ailment. Regardless, any team that trades for Peralta will want to know the why, and they’ll certainly have a plan in place to remedy it. 

Despite a disappointing season, Peralta’s trade value hasn’t suffered the same fate as his results. If he had a repeat performance of 2025, his value would undoubtedly be higher, but 2025 saw him way outperform his ERA estimators. Fortunately, front offices don’t care much for ERA these days, which means the right-hander's value is largely static from this winter. So, while the Mets are unlikely to recoup two top-100 prospects, that mostly comes down to them getting Peralta’s first 20 starts of the season.
