Casey Mize is pitching better than ever in 2026

Casey Mize has had an fascinating profession since being drafted 1st general in 2018. Despite profession highlights that embody a Minor League no-hitter in his AA debut and a 2025 All-Star Game look, Mize has typically felt underwhelming for a one-time prime prospect. Some of that is as a consequence of accidents like Tommy John surgical procedure wiping out most of 2022 and 2023, a few of it is as a consequence of rotation mate Tarik Skubal outshining the whole American League for nearly three full years now, and a few of it is simply unfair expectations. Regardless of metric, Mize has been a strong, if not thrilling, main league pitcher.

Coming into 2025, Mize was the proprietor of a 4.36 profession ERA and 18.2% strikeout fee. Put these collectively and also you get a reliable backend starter. 2025 was a step ahead, as he earned his first All-Star look, bumped his strikeout fee to 22.2%, mainly league common, and lowered his profession ERA right down to 4.19. By ERA, his 2025 season was a bit bumpy from the primary half to the second, however a mixture of a excessive BABIP and a low strand fee down the stretch hid the truth that he regarded a bit better below the hood. His second-half strikeout fee was 24% as he added a little bit of vertical motion to his fourseam and at last began getting better outcomes along with his splitter. He steadily regarded extra snug as he acquired additional away from the accidents that had plagued him earlier in his profession.

Coming into 2026, expectations have been for Mize to be a wonderfully wonderful third or 4th starter. The greatest optimists amongst us may need hoped for an additional small set of enhancements to construct on the elevated strikeouts he flashed down the stretch. Once Reese Olson went down with a shoulder damage, it grew to become clear Mize would wish to assist stabilize the center of the rotation behind Skubal and Framber Valdez.

Five video games into 2026, Casey Mize seems like the very best model of himself we have seen in the Major Leagues. Right now, his ERA sits at 2.51 and his strikeout fee is a whopping 27.4%, every profession bests. Yes, it is early in the yr, and sure, I do know he has an 83% strand fee, so he’ll finally begin leaking extra runs. That’s inevitable. It’s additionally okay. This early in the yr, course of stats like strikeout fee or pitch combine may be much more indicative of a change in expertise than a descriptive stat like ERA, and fortunately, two identifiable modifications appear to be fueling this early season excellence.

The first is pitch combine. After years of trying to find the correct third pitch to pair along with his 4 seamer and splitter, Mize – doubtless with the assistance of Chris Fetter, et al. – appears to have discovered the correct mixture thus far. Gone are the cutter and knuckle curve he launched in 2024, and the ‘slurve’ from 2025 has seen its utilization drop to near-negligible quantities. Instead, he is utilizing a easy 4 pitch combine: 4 seamers, sinkers, splitters, and sliders.

Like lots of pitchers, Mize has began spamming his secondary pitches as a result of they’re simply outright better choices than his fastballs. Mize does not throw notably onerous, averaging a bit over 93 mph on his heater after shedding a bit of fuel from his post-TJ peaks of 2024, and that 4 seamer has by no means gotten sturdy outcomes. Not even throwing it on the prime rail with elite extension has saved it from subpar form and velocity in the previous. Only throwing it round a 3rd of the time helps negate all that. Hitters are much less more likely to hunt fastballs, making it simpler to get away with them, and the extra you throw your greatest pitches, the much less doubtless anybody is to actually do harm in any case.

The second large change is in his pitch motion. When in comparison with 2025, each considered one of Mize’s pitches is transferring extra. Here’s a fast breakdown: the 4 seamer is operating 2 further inches armside, the splitter is operating 1 further inch armside, his sinker is breaking downwards 1 further inch, and his slider is each dropping and tailing 1 further inch. Even the slurve is dropping 6 extra inches and tailing about 5 extra inches, though it is such a small pattern measurement that appears a bit deceptive. Considering a baseball is about 3 inches in diameter and a bat is about 2.5 inches in diameter, an additional inch or two of motion throughout the board is a giant deal.

With this further motion you’ve got a great deal of weak contact and extra strikeouts. Mize is at present permitting probably the most mushy contact, the least onerous contact, and the second-highest flyball and infield flyball charges, of his profession. Soft flyballs do not actually have a tendency all that a lot, particularly in Comerica Park, so this appears like an excellent path ahead for Mize. It won’t work as properly in a smaller stadium, however hey, he is a Tiger, not a Red.

As good as these popups are, the additional strikeouts are positively extra thrilling. It’s early, however Mize has fairly actually by no means had a five-game stretch with this degree of strikeout upside earlier than. Below I’ve included considered one of my favourite visuals for early season evaluation, a ‘rolling common’. The graph exhibits Mize’s common stroll and strikeout charges over each five-game pattern since 2024; it is fairly apparent that early 2026 stands out from the remainder.

Right now, Mize’s strikeouts are up a ton from his earlier regular. Occasionally he would flash these things for an excellent recreation or two, however he is by no means proven a capability to take care of a 25%+ strikeout fee for even 5 begins at a time till now. That, paired along with his stroll fee staying fairly constant and his mushy contact expertise trending up, all on the identical time, have me cautiously optimistic this is an upgraded Mize. He won’t run an ERA below 3.00 all yr, however this is the high-floor, mid-rotation or better arm all of us envisioned out of school. It’s simply too unhealthy it till it took his stroll yr to achieve this level.
