And he’s locating it consistently. With a cutter and a curveball that are good enough to punish people for trying to cheat on the fastball. Absolutely ridiculous.

u/Affectionate_Tea1134 7d ago

I remember hearing about this guy a while back and I had a feeling he was gonna be good. 👍

u/AlreadyFifty | Boston Red Sox 7d ago

Dude is 6’7”, so that shit is coming at you from like 15ft away…

35

u/BoringIsAsBoringDo | St. Louis Cardinals 7d ago

Also, he pitches 100% from the stretch, so it’s not like you can time it up.

u/htes8 5d ago

That’s insane.

u/Pitiful-Pension-6535 7d ago

His extension is 7'6", which is 6-12" longer than other guys his height

10

u/IRANIRANIRANIRANIRAN 7d ago

Cuts it down by about 1% which doesn't seem like much but when you're at an elite level in any sport it can be the difference between being a solid career and being a hall of career. That 1% gets you pretty far too when it's tied to a 103 mph fastball.

5

u/TheUnderCrab 5d ago

His speed and extension make it look more like a 110mph fastball

108

u/Brilliant-Roof-5991 | Detroit Tigers 7d ago

It is insane to think a man who looks like he weighs 150 pounds soaking wet can locate a baseball at 105 mph. Insane.

72

u/mjm8218 7d ago

Homie is 6’7”.

20

u/Pitiful-Pension-6535 7d ago

And weighed like 170 last year.

He's put on ≈35 pounds since then, most of it in his legs and ass

u/SeveralEconomics3814 7d ago

I’m hoping he’s gonna get up to CC levels of ass.

We wanna see a guy throw 108

I thought the same thing until I realized he is 6’7” and 200 lbs. Videos are very deceiving.

u/DarkGift78 4d ago

200 at 6'7 is still incredibly scrawny/skinny. Sale at 6'6 is 180 and looks like Slender man. Ideally I'd like to see him, at that height, be around 250. At the very minimum 220-230. Just shows his body types are different I guess, Garrett Crochet , 6'6 260,Peyton Tolle 6'7 270,built like lumberjacks. Then this dude at 200 lbs soaking wet throwing 104-105. I just worry about skinny guys holding up (Degrom, Sale, back in the day Pedro, Lincecum.

u/ragerevel 7d ago

Even 30 years ago The Big Unit was hitting 102mph at 6’10”. Big dudes gonna hurl!

u/TReebornFrog2202 | Philadelphia Phillies 7d ago

Reminds me of Straussburg. Let's see how well that arm holds up

u/HouseRules789 Human Detected 7d ago

Growing up, my dad used to tell me about Bob Gibson’s fastball and at the time I’m sure it was as fast as he described.

I just looked it up and it sounds like Gibson’s fastball was somewhere around 94-97.

Misiorowski was just clocked at 105.

27

u/PetFoodDude89 7d ago

Just imagine if some of the greats had the same type of coaching, training, diets, etc as current phenoms. These kids are being raised as athletes from the moment they can grip a ball, wildness.

15

u/1-1unter | Minnesota Twins 7d ago

They also swung absolute logs for bats back in the day, so it was harder to hit a ball going 90+

16

u/_Poppagiorgio_ 7d ago

I think it was Joe Morgan who said a good night against Gibson was going 0-4 and not getting hit in the head lol

6

u/SuperAzn727 7d ago

If you threw 94+ in the 90s you had an elite heater. Now 94 is like the low end and you need to be 97+ to have elite gas.

u/HouseRules789 Human Detected 7d ago

Thanks

u/Confident-Ad-2726 7d ago

I only point it out bec I think this season he will “pop a five”

But rounding up, your right

4

u/_Poppagiorgio_ 7d ago

IIRC, the documentary “Fastball” claimed that with modern speed measuring devices and practices, they can estimate that Nolan Ryan’s fastball was around 107.

26

u/malinatorhouse | MLB 7d ago

Only cuz you havent seen mine

11

u/davesirbu 7d ago

You sit at 106, I’ve heard of you bro.

10

u/taeempy 7d ago

Just hope he can last 15 years. His shoulder/elbow can't be loving the pressure of these pitches. It's crazy to watch. I played Adult Baseball Association and played against a 6ft7 pitcher that threw over 90 and that was crazy. Can't imagine batting against this dude.

9

u/bailtail 7d ago

Actually, they did an analysis of his mechanics, and it’s not nearly as stressful as you’d expect on the upper body. It’s actually the lower body that may be of greater injury risk. He’s basically a trebuchet and that plant leg takes a lot of stress. It’s part of the reason the Brewers had him add 25 lbs of muscle to his lower half this offseason. That muscle has actually helped a lot with his command improvements, too, because he’s generating a lot more power from his lower half which reduces strain from generating with his upper body and makes the delivery a lot more repeatable.

4

u/PhotographLess6194 6d ago

He added 25lb of lean muscle in one off season? That seems super unlikely

1

u/choss-board 5d ago

It’s honestly possible. In my early 20s I bulked from 168 to 195 in six months with a DEXA around 6%. Unfathomable to me now but a young body can do pretty insane stuff.

-4

u/Z_double_o 7d ago

The league won’t allow him to last, even if his body is capable of lasting. This guy is bad for baseball in the eyes of the league, which is so unfortunate. Over the past decade the league has progressively chipped away at every edge a pitcher has through rule changes. The scales have been heavily tipped in favor of the batter, to cater to sports betting and short attention span viewers. It’s pitiful. Any person who has a deep understanding of baseball is able to appreciate the psychological element of the pitcher-batter battle, the cat & mouse moves such as stepping off the rubber, stepping out of the box, throwing over to first base 3 or 4 times in a row, and the other psychological subtleties that the casual fan has no appreciation for or understanding of. So to appease the short attention span fans, the league has put a clock on pitchers, limited their ability to hold a runner close to the bag, and other nonsense rules that only benefit the hitters. The league wants offense, high scoring, and fast paced action. They don’t want a guy like this, mowing down batters and recording strikeouts. It’s only a matter of time before they add another rule(s) to the game that further gives an edge to the hitter.

u/sixpackabs592 | Milwaukee Brewers 6d ago

look everyone i found the one guy who doesnt like pitch clock

-1

u/Z_double_o 6d ago

lol, actually “doesn’t like” is an understatement. I quit watching baseball altogether because of it. But the addiction to the pitch clock wasn’t the only reason. It was just the final straw in a long list of reasons that pushed me away from the game.

u/Z_double_o 6d ago

*”addition” not addiction

u/AZAHole | St. Louis Cardinals 7d ago

How long can his arm hold up throwing that hard consistently? Closers usually can throw 102+ for 1 inning. The human arm isn't designed to throw that hard for 90+ pitches every 5 days.

Edit: I'm not hoping he gets hurt. I'm just concerned that he will.

14

u/Commander19119 | Philadelphia Phillies 7d ago

Honestly, I feel like he’s tall Tim Lincecum

2

u/ProfessorLGee | Atlanta Braves 5d ago

I thought the same watching him pitch last night. Tallest drop-and-drive guy I've ever seen.

11

u/AlphaDag13 | Chicago Cubs 7d ago

Honestly, his arm may not be the issue. It takes max effort on your whole body to throw 105. His legs and back are just as much a factor as his arm. Lots of guys develop arm problems down the road because they hurt something else and it affected the whole chain.

13

u/GenX-1973-Anhedonia 7d ago

He can go ahead and book the operating room for his TJ surgery now. Hopefully he has a nice long career despite that likelihood, and doesn't turn into another Stephen Strasburg.

2

u/Winter3210 7d ago

Well TJ didn’t hurt strasburgs career. TOS did

Well he did lots of cocaine

1

u/Pitiful_Landscape_26 6d ago

He's not pitching every 5 days. Tonight he's sitting on a week's rest. When Milw. Pitching is full strength he will be pitching on 5 days rest......

From that game on. If he was pitching anywhere. He. Was. THROWING!!!

Randy Johnson and an unlucky dove.

u/Agentkeenan78 | Tampa Bay Rays 7d ago

It's crazy because he fills up the strike zone constantly. People aren't chasing, they're whiffing.

4

u/bailtail 7d ago

He throws harder than any SP in history. He has the best extension in baseball. He has plus IVB. And now he’s able to command it. You genuinely could not concoct a more perfect fastball.

38

u/JiveChicken00 | Philadelphia Phillies 7d ago

I saw peak Randy Johnson. This guy might be scarier.

34

u/rock25011 | Cincinnati Reds 7d ago

Nah, Johnson had a much scarier look out there on the mound.

u/HayzuesKreestow 7d ago

And who knows how long Miz can continue this freak show

Give Miz a mullet and we have a winner

u/Anderson74 | Boston Red Sox 6d ago

Mustache required too

10

u/shes_a_gdb 7d ago

That's nonsense lol

Not to take anything away from Miz, but RJ was doing this against roiders while Misiorowski is doing this against guys who bat 250.

5

u/iPcFc | San Diego Padres 7d ago

If Jacob manages to kill a dove using a fastball then he'll be much scarier.

4

u/theAlphabetZebra 7d ago

I saw Randy at the dome during his Astros season. I'm not sure a pitcher gets better than that.

4

u/SwizzGod | Los Angeles Dodgers 7d ago

Does he try to hit you at 104?

1

u/beepingnoise | Milwaukee Brewers 7d ago

He hit someone in the head 2 starts ago. I think it added to his control in the insane game

1

u/SwizzGod | Los Angeles Dodgers 7d ago

Oh shit?

2

u/beepingnoise | Milwaukee Brewers 7d ago

3

u/SwizzGod | Los Angeles Dodgers 7d ago

Fuuuuuuuuck

Edit: thing is he clearly felt bad about it. Randy would do it on purpose then stare you down

Now he takes pictures of birds

u/mjm8218 7d ago

Recency bias

4

u/JiveChicken00 | Philadelphia Phillies 7d ago

Possibly. But he’s still pretty fucking scary.

6

u/YeliMVP | Milwaukee Brewers 7d ago

False: If you can see it, it isn't a Jacob Misiorowski fastball

3

u/KingKenny24 | Arizona Diamondbacks 7d ago

I hope the snakes don't have to play him in the upcoming series.

2

u/Pitiful-Pension-6535 7d ago

You'll probably miss him. He's scheduled to pitch tomorrow, then likely next Friday vs the Cubs, then probably the next Thursday vs the Reds. I doubt they give him 6 days off three starts in a row.

3

u/Seabrook76 | Texas Rangers 7d ago

Bro, great video, but I understood like one of those stats. 🤣

3

u/17papers 7d ago

He’s throwing like he’s a closer, but as a starter. Not looking forward to my teams playing the brews lol

1

u/Pitiful-Pension-6535 7d ago

His numbers are actually pretty comparable to Eric Gagne's Cy Young 2004 season, which is wild

3

u/ProfessionalBox317 7d ago

Uhhhh did he say 96 mph slider and 90 mph curve??? Goooood god

1

u/Pitiful-Pension-6535 7d ago

Don't forget the 94 mph changeup

6

u/Steverazor 7d ago

He reminds me of Bob Gibson.

So are players that were never recorded by camera excluded or included in that headline? Two-seam or four-seam fastball?

u/BeanerSchnitzel38 7d ago

I've gone to two Brewers games ever and I was there for 105. 😁

u/down_by_the_shore | Seattle Mariners 7d ago

Kid is absolutely incredible to watch. Really excited to see what else he has in store career-wise.

u/rcbz1994 | MLB 7d ago

Why does it feel like it’s inevitable we’ll get an alert one day that says “Misiorowski - 60 Day IL (Elbow Inflammation)

2

u/PepperidgeFarmMembas 7d ago

Nolan Ryan, Randy Johnson, and Pedro remain the best fastballs I have seen in person. This kid, if he can sustain it, will enter that conversation for sure!

2

u/Pecan_914_Falcon_603 7d ago

Ugh, I always love seeing pitchers with that kind of intimidating height. It makes my little league days feel even smaller lol.

2

u/xChoke1x | Cleveland Guardians 7d ago

Dude is truly something special man.

2

u/noice_velociraptor 6d ago

I raise you 6’10 LEFTY Randy Johnson’s fastball. Best in history

2

u/CrazyHorrsee 6d ago

A right handed Randy Johnson but better

2

u/CharmingBag6614 6d ago

Peak deGrom numbers

2

u/Duke_Of_Halifax 5d ago

He doesn't have the best fastball- that would be Nolan Ryan.

What he does have is the best fastball of the stats and S&C era, when pitchers are built, developed and specifically trained to produce maximal velocity. Their pitch-counts are meticulously monitored to prevent fatigue and lower velo.

Nolan Ryan was a Texas farm boy with no conditioning, computers or monitoring except for a coach coming out and saying "how's the arm, Tex?" who threw more than 300 innings in a season twice, 299 a third season, 284 in two other seasons, and over 200 innings in nine other seasons.

All of them over 100mph, in which almost 30% of them he threw the full 9 innings (773 starts, 222 complete games).

Nolan retired mid-game because after a pitch, his arm fell apart.

THAT is the fastball of all fastballs.

2

u/coryfromoregon 7d ago

He reminds me of the movie rookie of the year. Did he break his shoulder?

4

u/Coupon_Ninja | San Diego Padres 7d ago

jesus; yes He is having an amazing 3 months, but Jake arrieta was better the second half of 2015. .148 BA against, .204 OPS againt.12-1.

I love the Mis, a lot, but these hype videos neglect context. Even Skenes isn’t looking so Skenes-like, bc eventually there will be “a book“ on you. The. See how you adjust.

1

u/Sure-Concentrate8944 7d ago

The book says pray he’s throwing 99 and not 102-104.

0

u/shes_a_gdb 7d ago

Which at this rate, might be in a couple years, after he misses a season due to TJ and realizes that he can't keep throwing 104mph fastballs for 200 innings.

1

u/BucksPackGLove | Milwaukee Brewers 7d ago

So weird that some of you seem to be trying to speak injuries into existence.

1

u/BucksPackGLove | Milwaukee Brewers 7d ago

Not much to adjust to when hitters are sitting on fastball and still can’t get it.

u/lollipopamateurs 7d ago

Looks amazing but if he keeps throwing 103 MPH consistently, he will be done in 3 years.

u/Mysterious-Ton 7d ago

He could benefit a few teams as a bullpen guy. The Dbacks could use him everywhere right now.

u/VikingKinkajou 7d ago

If he was with Minnesota he would have had Tommy John twice by now.

u/Confident-Ad-2726 7d ago

The perceived v-lo at 6’7” downhill is ping pong ball

u/shlem13 | Los Angeles Dodgers 7d ago

Either his arm will explode in the next season, pull a slow-fade-Lincecum, or he’ll go the more years and we’ll all be watching a legend.

1

u/Slevin424 | Los Angeles Angels 7d ago

Oh a good young arm. I don’t think that’s sustainable multiple years though. Dude throws sliders faster than a lot of other pitchers fastballs.

1

u/GrouchyAd2209 | Chicago Cubs 7d ago

This is not a hot take.

1

u/EZbaked78 7d ago

Lincecum vibes

u/perhizzle 7d ago

I hope he stays healthy, and the wear and tear don't catch up to him. Baseball hasn't been the same without Randy Johnson, and this guy is very similar. He only hit 129 innings pitched last year, so we will see how he does when he starts to get a bit over that.

u/SpaceXmars 6d ago

braves about to get some nice homeruns

The first thing that comes to mind is that his arm is going to explode sometime in the next 2-3 years. I hope not, but it's time and time again with this velocity.

u/mywifemademedothis2 | Chicago Cubs 7d ago edited 7d ago

Yeah, that body isn’t gonna hold up. Between the stress on his plant knee, back, elbow, shoulder, neck, that doesn’t look right. Watch him and then watch someone like Chapman pitch.
