On January 21, 2026, New York Mets president of baseball operations David Stearns traded away two prospects to the Milwaukee Brewers for Freddy Peralta. The franchise expected the 30-year-old former All-Star to give them an ace.
However, after an atrocious outing in Toronto, Peralta looks like a shell of his former self. For example, his ERA rose to 4.81. During his entire nine-year career, Peralta has never endured such a troubling stretch of starts. More important than his 5-7, Peralta’s inability to throw his pitches with the same success continues to confound observers.

The Mechanical Identity Crisis Catching Up to Peralta’s Fastball
To truly comprehend why Peralta’s numbers dipped, you need to look past the surface stats and focus entirely on the raw data. Granted, Peralta touched 99 miles per hour against the Blue Jays, but he stopped throwing the fastballs up in the zone, which would normally lead to mishits and whiffs. This can be attributed to one factor: arm angle.
Last season, Peralta threw his pitches at a 38-degree angle, according to Baseball Savant. Now, the righthander fires his offerings at 32 degrees, which leads to an almost one-mile-per-hour decrease in velocity. Basically, Peralta’s fastball stays in the strike zone longer because of its diminished velocity. The Mets ace becomes hittable after that.
About a month shy of the trade deadline, Freddy Peralta is getting lit up again.

The Total Evaporation of His Elite Slider Indicates a Significant Decline in Performance
With a power arm like Peralta, the Mets hoped that his slider would continue to serve him as well as it did in Milwaukee. First, his 2026 spin rate (2,341) pales in comparison to last year (2,454). The lower arm slot, according to film study, shows a struggling slider. Sliders need a higher arm angle and extension to generate spin. In turn, the spin pushes the pitch away from righties and into lefties. Without that, the pitch will hang and become an easier target for Mets opponents.

The Philadelphia Fallout that Could Define a Season
Whenever Peralta’s Mets tenure ends, June 20, 2026, will mark the date everything fell apart. That Saturday night in Philadelphia saw the Phillies torture the veteran. Peralta’s stat line stood out for all of the wrong reasons (2.2 IP, 10 H, 10 ER). Phillies star Kyle Schwarber destroyed a couple of pitches that landed over the fence. Now, sporting a 1.416 WHIP, what can the Mets do?
Salvaging the Trade Deadline Assets of a Last-Place Team
In essence, Peralta’s mounting losses continue to submarine the Mets’ hope of landing quality prospects in return, especially since they reside deep in the National League East basement. Not to mention, despite his previous regular-season dominance, Peralta does not pitch the same in the postseason. In his last 20.1 playoff innings pitched, he’s allowed 15 earned runs and six home runs.

Will a contender send over highly vaunted prospects for him? Stearns needs to find a way to balance two factors in potentially dealing with Peralta. He may not receive in return what he gave up to acquire Peralta. Also, Peralta will enter free agency after the season, potentially driving down his asking price for a pitcher that could amount to nothing more than a late-season rental.
