It’s been darkish right here at FanGraphs for a couple of days, so admit it — you’re determined to learn something proper now. How a couple of roundup of research on three pitchers that went off the market proper earlier than our vacation hiatus?
Griffin Canning, Michael Soroka, and Patrick Sandoval all match someplace between the again of their new crew’s rotation or the entrance of its starter depth; every acquired offers commensurate with these expectations. If the going price for a fourth starter nowadays is one thing like $15 million AAV (Alex Cobb obtained one 12 months and $15 million, Matthew Boyd obtained two years and $29 million), this trio might be one tier under that.
Do these three signings, grouped collectively, imply something specifically? In all probability not. Every year, the starter/reliever binary grows blurrier, and maybe sometime, each pitcher will throw precisely three innings and the excellence will disappear utterly. Maybe every of those signings brings us nearer to that day; Soroka, specifically, appears finest served to undergo a lineup as soon as after which head out on his means. For numerous causes, the expectation for all of those pitchers ought to be someplace within the 80- to 120-inning vary for the 2025 season. However for now, no additional developments might be drawn. With out additional ado, right here is the lowdown on the three hurlers.
Griffin Canning
Canning drew some consideration on the pitching nerd web earlier this 12 months as a result of remarkably unremarkable form of his fastball. The picture under is courtesy of Max Bay’s dynamic lifeless zone app:

As a result of Canning throws his fastball from a roughly league-average arm angle (45°), a league-average launch peak (5.8 toes), and with league-average journey (16.2 inches of induced vertical break), the pitch — in principle! — strikes on a trajectory that hitters anticipate. (I say “in principle” as a result of, as Remi Bunikiewicz identified, Canning does a fantastic job hiding his fastball through the windup, complicating any perceptive evaluation.)
This fastball was the bane of Canning’s existence in 2024. He did qualify for the ERA title, one thing solely 57 different pitchers might declare they did, however his 5.26 FIP was worst amongst these certified starters, and his strikeout price was third worst. That strikeout price dropped almost eight share factors from 2023 to 2024, and the efficiency in opposition to his fastball defined basically all of that drop. The whiff price on Canning’s three different main pitches stayed just about the identical; on the fastball, the share of swings that resulted in misses went from 28% in 2023 to only 14% in 2024.
A drop in velocity seems to be the primary offender for the decline in efficiency. The four-seamer averaged 94.7 mph in 2023; that dipped to 93.4 mph in 2024. Might a 1.5-mph distinction in velocity be the whole clarification? I’m inclined to suppose that the reply is usually sure. But it surely’s additionally potential that the decline in slider high quality impacted batter efficiency in opposition to his fastball. Canning’s demise ball slider dropped three fewer inches relative to 2023, decreasing the separation between his fastball and his main out pitch in opposition to right-handed hitters.
Might a diminished function assist Canning return to his prior kind? These concerns may very well be a part of the plan. The Mets make use of one thing like eight starters; Canning sits exterior the favored 5. Assuming good well being, it’s seemingly that they are going to deploy him in two- or three-inning bursts, maybe permitting him to get again to that mid-90s velocity on the heater. Even in a swingman function, the $4.25 million contract makes good sense — with fewer workload obligations, it doesn’t really feel unreasonable to anticipate Canning to ship one thing like a 4.00 ERA over 100ish innings. And if accidents do strike the rotation, he can stretch out to a starter’s workload. Both means, there’s a job to play on this period the place high quality innings might be troublesome to come back by, particularly within the late summer time months.
Michael Soroka
Soroka exploded after a midseason transfer to the White Sox bullpen. As a reliever, Soroka struck out 39% of the hitters he confronted, which might’ve ranked second in all of baseball.
Curiously, this wasn’t a case of Soroka ramping up the stuff over 15-pitch spurts. Not like these pitchers topping the strikeout leaderboards — Mason Miller, Edwin Díaz, Josh Hader — Soroka did it largely in chunky multi-inning appearances. Soroka pitched 36 innings out of the bullpen; all however 5 2/3 of them got here in appearances that spanned two innings or extra. In these barely shorter appearances — he averaged almost 5 innings per look as a starter and a couple of 1/3 as a reliever — the strikeout price by some means tripled.
After transferring full-time to aid work, Soroka added 1.5 mph to his four-seam fastball. However the four-seamer isn’t something particular; as an alternative, at 94 mph with lifeless zone-ish motion, it’s largely there to arrange the slider, which generated almost a 42% whiff price.
What’s so particular in regards to the slider? It isn’t the rate — it averages simply 82.2 mph, properly under the common for main league sliders. However its form is distinct. There are slower curveballs that resemble the motion profile, however exterior of Bryan Abreu, no person actually throws a slider with the mixture of depth and sweep that Soroka manages to get. Beginning Could 18, when Soroka shifted to a bullpen function, the slider averaged -4.5 inches of induced vertical break with 5.2 inches of sweep, transferring sharply on two planes.
However averages obscure the total fact. Soroka also can manipulate the pitch to maneuver in quite a lot of break patterns. Take a look at the vary of motion profiles on his slider, seen in yellow on his pitch plot under:
Soroka can agency it up, throwing it extra like a gyro slider at 84 mph with zero inches of induced vertical break:
However he also can bend it like a curveball, dropping over 10 inches greater than his firmest sliders:
(Take a look at poor Spencer Torkelson there — I believe he was anticipating the gyro.)
Between the similar frequency of the fastball and slider, the distinct two-plane motion profile, and the variety of potential shapes, Soroka had batters swinging and lacking greater than virtually any pitcher in baseball.
Evidently, the Nationals, who gave Soroka $9 million on a one-year deal, plan to make use of him as a “starter.” Given his utilization patterns as a reliever, I’m not precisely positive what meaning. I’d anticipate that the Nationals will inform Soroka to let it free for 60 or so pitches, simply as he did in Chicago, and he’ll tackle 12 or 13 hitters in a recreation. Like Canning, I believe Soroka will find yourself nearer to 90 innings than 180, letting his finest stuff cook dinner in outings that sit someplace between a one-inning shutdown reliever and a starter attempting to show the lineup over thrice.
Patrick Sandoval
Sandoval, who signed a two-year, $18.25 million cope with the Purple Sox, is an ideal match for his or her “no fastballs” organizational philosophy. This man hates four-seamers now — they made up simply 16% of his pitches in his injury-shortened 2024 marketing campaign, by far a profession low. No matter batter handedness, Sandoval mixes in all six of his pitches, however he works them in in a different way relying on whether or not he’s dealing with a righty or lefty. A plurality of his pitches to righties have been changeups; to lefties, Sandoval spammed his slider and sweeper over half the time.
As one would anticipate with a pitcher who throws all that junk, Sandoval struggles to get the ball within the strike zone. He ran a ten% stroll price final 12 months; even in his glorious 2022 marketing campaign, through which he racked up 3.7 WAR, his stroll price was above 9%. The walks are simply a part of the bundle with Sandoval, however the hope is that at his finest, he can pitch round them, hanging out sufficient hitters and staying off sufficient barrels together with his numerous pitch combine and refusal to throw something straight.
Sandoval is more likely to pitch the fewest innings of this trio in 2025. He tore his UCL and was shut down in mid-June earlier than present process Tommy John surgical procedure, so he’ll miss a giant chunk of the upcoming season. When he returns, it figures that he’ll assume a conventional starter’s workload, although following the Walker Buehler signing, Boston’s rotation appears to be like fairly packed. Finally, this deal is usually a 2026 play, with some good depth for the tip of subsequent 12 months as a bonus.
Conclusion
None of those guys is simply too thrilling. All of them have stanky fastballs. However every has a purpose to consider that he would possibly contribute surplus worth on a modest deal. In the long run, that’s what a minor pitcher signing is all about.
