Freddy Peralta: A Lost Season that Was Saved

Entering his contract year, Freddy Peralta was one of the biggest offseason moves, coming to the Mets from Milwaukee as a top-20 starting pitcher in fantasy ADP. For Peralta, the Mets, and anyone who drafted New York’s prospective ace this season, 2026 is a year that has not gone as planned. But following a fresh start in Florida, it seems as if Peralta is back on track, at least for now. We will look at this rollercoaster season for Freddy Peralta, what this means for his fantasy value in 2027, and what he can learn from both his time in New York and Tampa Bay.

Freddy the Met

The New York Mets will certainly end the season in the conversation for one of the most disappointing seasons given pre-season expectations, and Peralta has a case for the most disappointing offseason acquisition. As a Met, Peralta posted a 4.99 ERA against a 3.86 xERA, 4.45 FIP, while his strikeout rate was 22.1%, walk rate 9.4%, giving a K-BB% of 12.7%. Not the production of an ace that the Mets had hoped for in a contract year, no less.

While we will come to what gave him success in the following section, his struggles mainly came from his inability to command his pitches. That command breakdown shows up clearest in the pitch values. Every offering in his arsenal graded below average as a Met, but the changeup stood out as a problem. It posted a -4.6 run value on 20.8% usage; his second-most-thrown pitch was mainly working against him. His swinging-strike rate (11.3%) and CSW% (25.2%) were both close to league average, so the stuff wasn’t the issue. He wasn’t able to really generate any extra whiffs, and it got punished often when hitters swung. A 38.2% HardHit% and a 68.4% strand rate turned an ordinary contact profile into a near-5.00 ERA.

Revival in Tampa

While it may have taken a little time, the Tampa pitching machine has added another success story to its development resume. Particularly over the last month, Freddy Peralta has been given new life in what looked like a lost season. Peralta has thrown 28.2 innings across five starts with a 0.94 ERA, striking out 23 against a .143 opponent average and a 25.8% whiff rate. The driver of this success has been what the Rays pitching lab has been able to unlock with this aforementioned changeup. As a Met, Peralta threw his changeup 20.8% of the time, and it graded as his worst pitch by value at -4.6 runs. But rather than bringing that percentage down, the Rays have actually leaned into it further, dropping his slider/sweeper and utilizing his changeup against both left-handed and right-handed bats.

From the heatmaps of his changeup usage with the Mets, there is significant overlap between Contact% and Swing%, proving his struggles with that pitch, which led to the negative run value, reinforcing the point made about the HardHit rates during his spell in New York.

If we do the same with his changeup with the Rays, we can see the immediate difference. The heatmaps below, from when he was traded to Tampa at the beginning of August, show significant red on the right heatmap (swings), where the left (contact) shows far less.

The results back up the shift. His changeup has produced a 33.9% whiff rate across these five starts, the best mark of his three primary pitches, and the location data supports a tighter approach, not a new shape. As a Met, the pitch’s contact zone was broad, centered low in the zone and spilling below it. The contact and swing maps could be layered on top of each other with not much to differentiate them. With the Rays, he’s not only throwing this pitch a lot more but locating it much better in the bottom left corner of the zone, inducing more swing and miss.

The fastball has played a role too, climbing in usage as the stretch has gone on and sitting comfortably in the mid-90s throughout. He got up as high as an average of 96 mph in his most recent start, with a season-high induced vertical movement coming with this velocity as well.

What to Expect in 2027?

Well, given how much of a difference there has been in Peralta’s performance this season, it’s safe to say where he lands will be a big factor, and he will not be bulletproof in terms of landing spots. Given some reports about how well he handled, or could not handle, the pressure that comes with playing New York, and how well he’s performed in markets where the lights are not quite as bright in Milwaukee and Tampa Bay, it could be as simple as that. But having a pitching department that can perhaps inspire confidence, as Tampa have done with his changeup, is more critical. Entering 31 years old, this could be his last opportunity to land a sizeable contract, but given his instability this season, he may have to settle for a prove-it deal.

Regardless of where he lands or what contract he is given, Peralta has shown us enough this season that he can still be an incredibly valuable fantasy asset, despite his struggles. His arsenal is diverse enough, and his fastball is holding up late into the season; he still has a lot to offer. Where the Rays have valued his changeup, another team might want to increase the usage of his sweeper, which, even in Tampa, has been his best statistical pitch despite being the least thrown. His best starts have come when his fastball has dominated; in multiple starts in September, he has been able to get well above his 94 mph average, sitting around 96 mph in some starts with the same season-high induced vertical break mark of 19 inches. This will ultimately be the key to his success; both his changeup and sweeper have elite stuff for secondary pitches, which raises his fantasy ceiling, but the floor will be set by the fastball.

This season was a rollercoaster year for Peralta owners, which could not be more perfectly illustrated by his FanGraphs Fantasy Player Card.

Following a down 2026, where he was drafted as SP15 or 16 before the season, depending on where he lands, there could be a lot of value to be gained from Peralta in 2027 fantasy drafts.
