Better of BP 2025: Change (Within the Home of the Fly Balls)

A pair weeks in the past I posed the query: How a lot ought to I care that the Angels had been the staff that drafted Ryan Johnson? I—as I typically do—perhaps circled round it some with out answering. The broader query—how a lot does org context matter for prospects—is one we’ve struggled with over my decade on the BP Prospect Staff. The reply is “clearly, it issues,” however how do you bake that into an analysis or a rating?

9 years in the past now,  I wrote the 2016 Mets prospect record. For the needs of this train, please don’t look previous primary. I threw a 60 on his slider (I’d say future, however he was within the majors and making playoff begins the earlier season) with this notice:

“Like most Mets pitchers below Dan Warthen, he has began to mess around with a tough slider (the vaunted “Warthen Slider”). It’s not as far alongside as his rotation mates, however he has the best armslot for it, and the developmental observe document right here is superb.”

Now we have pitch-level knowledge for the 2015 common season. Matz threw 11 sliders that yr and received zero whiffs on it. He’d throw it extra in 2016 with an improved form—extra depth—and improved outcomes, however it tended to make his arm harm intermittently and he’s been primarily a sinker/change pitcher since 2019 or so. He’s underperformed his top-10 nationwide prospect rating from that offseason, however he’s been broadly a quantity 4 starter, simply not the form I’d have guessed (outdoors of the apparent sturdiness considerations). He additionally ended up not being the form of pitcher the Mets had been making an attempt to develop in that period, however I definitely let org contact information my slider projection at that time. And he was throwing it, I wasn’t conjuring it from skinny air.

The most effective argument about being staff agnostic with regard to evaluations, is org context can change rapidly even in the event you keep in the identical org. Dan Warthen was gone from the Mets 18 months after I wrote Matz’s blurb. Dave Eiland got here in and the emphasis on sinkers and changeups unfold past simply Matz shortly after. And naturally gamers can get traded. The Rays clearly made some extent to focus on Jackson Baumeister, Brody Hopkins, and Ty Johnson in trades final season. Smarter pitching dev groups decide gamers from organizations the place they’re below optimized on a regular basis, simply as they aim faculty arms from faculties that aren’t as up on trendy pitch design or utilization. The one fixed for pitching prospects is change, and growth is rarely linear.

We wish to say that prospect lists are a snapshot in time, so I believed it is likely to be helpful to have a look again at a few of our previous prospect reviews on one other Mets pitcher having a very good begin to 2025 to see what, if something, we are able to glean.

Griffin Canning, RHP, New York Mets

The Angels quickly transferring faculty prospects to the majors is nothing new. Canning was a second-round decide of the Halos in 2017 and was beginning within the majors by April 2019. That’s not that aggressive a path for a PAC-12 starter, and he did throw 113 good innings throughout three ranges in 2018. However we didn’t get a ton of photographs at rating or evaluating him. Canning didn’t pitch after the 2017 draft, though Wilson Karaman famous in his write-up on the Angels record that he was a possible first-round decide apart from well being considerations. After his fullish 2018 season we wrote this whereas rating him because the 56th finest prospect in baseball: “sturdiness and well being considerations could but restrict him to a mid-rotation final result, however he does have higher stuff than the standard mid-rotation beginning profile.”

Canning got here up in 2019, and pitched largely to the scouting report. He received above-average whiff charges on each his breaking balls, and whereas his heater received hit onerous when it received hit, it did run a 22% whiff charge. The subsequent 5 seasons had been typically marred by accidents—right here come the well being and sturdiness considerations—however typically talking, when wholesome he missed bats along with his secondaries, and his fastball received hit onerous. He began throwing his changeup extra in 2023 and 2024 for some motive—it’s common, however unremarkable—however at all times led out with the fastball. The Angels are fairly conventional with reference to how they need their starters to pitch, and Canning ended up with such a generic four-pitch combine that Jarrett Seidler referred to as him “Joe Random Pitch Combine.” He was dealt to Atlanta in return for Jorge Soler (and extra importantly, Jorge Soler’s contract) and was non-tendered shortly after.

At this level Canning appeared like a busted mid-rotation prospect. You would most likely blame accidents some, a nasty pitch combine some, a nasty fastball some (we all know much more about fastball form and the like than we did in 2019). If we had been rating 2019 Canning in 2025, he wouldn’t be a Prime 50 prospect due to how generic the stuff profile was. In the event you can’t discover a plus pitch, how certain are you able to be that any will find yourself even common?

Then the Mets signed him to a major-league deal for actual cash. On the time I didn’t assume a lot of it. They wanted to signal a variety of pitchers, and Canning has been fourth starterish previously and was probably keen to pitch out of the pen at this level. And hey Steve Cohen can afford just a few million for a punt, it’s cheaper than bailing out Gamestop anyway. The Mets didn’t simply throw Canning into the mixer although, they made two important modifications. One, they instructed him to throw his slider extra—it had at all times been his finest pitch—and two, they improved mentioned slider, giving it extra vertical motion on the identical velocity. Additionally they received a optimistic tweak on the fastball form, however he deploys his fastball as a secondary pitch now, and it’s generated extra strikeouts than the slider, as a result of hitters don’t count on it in two strike counts. He has above-average stuff now, and appears the a part of a mid-rotation starter (granted that’s the 2025 model the place you don’t need him seeing the nice hitters a 3rd time, not the 2019 model). Generally it truly is a long-term worth record. And generally you simply have to get off the Angels, however org context isn’t every part both. Now we have to alter our analysis context.

Canning having a tweaked breaking ball and pitch combine isn’t a shock insomuch because it was going to be obligatory, however there needed to be one thing to unlock. No matter our pitch grade projections had been for Canning, the underlying foundation for them was really feel for spin. He ran above-average whiff charges on each his breaking balls even when he was posting 5+ ERAs within the majors. It’s probably not a shock he discovered a workable breaking ball to be his major providing even when it’s not precisely the identical one he threw as a prospect.

It will get weirder while you have a look at pitchers like Paul Skenes and Jackson Jobe including pitches even after making the majors. Jobe himself is a very totally different pitcher now than he was on draft day—that’s one other main part of Jarrett’s Annual essay—however the basic good pitching prospect traits are nonetheless current in his arsenal. Skenes unintentionally discovering an elite splinker in a spring pen session isn’t projectable or predictable, however it’s additionally not a shock that an elite arm pace man who already made enormous stuff jumps year-over-year as an newbie discovered an efficient arm-side grip pitch. He was most likely going to in the end, whether or not it was a splinker, splitter, or kick change.

Is that this an argument to divorce our evaluations from discrete pitch grades to a extra holistic analysis of the participant’s underlying traits? Not as such. There’s simply going to be extra of a public/non-public info hole for a few of this. And you continue to would like they’ve proven the 11 sliders sooner or later. However it’s price noting groups—at the least the good ones—aren’t focusing on the 4 potential above-average pitch, good faculty performers like Canning as a lot as they used to.

If the final word puzzle is determining who will get main league hitters out, we now have to at the least acknowledge the trail to doing so isn’t so simple as water and develop, or a grade leap of command and changeup. It’s not seeing 5 good sliders out of 20 from behind house plate and telling your self “properly in just a few years he’ll throw extra of the nice ones.” There’s the truth is most likely an underlying motive he threw 15 unhealthy ones. It’s not simply trying on the projectable Texas prep arm that for $1.5 million within the third spherical and betting on the 20 kilos of fine muscle. However we aren’t pitching coaches both and I can’t simply say “give him a bridge cutter” or “that slot is best for a sweeper.” We’re on a dangerous knife’s edge on the skin as public evaluators now, as organizations grind down smaller and smaller developmental benefits. It’s not merely throw your finest pitch extra (though that definitely labored for Griffin Canning), however quite do you even have your finest pitch but?
