Seam shifted wake >>>>>
Actual Movement vs. Expected Movement What is expected movement? The amount of movement the pitch would have had if Magnus was the only force put on the ball. As we now know, seam orientation and other environment changes impact the way a pitch moves. Not all movement is created equal 🧵

If I would have done this on my Pennsylvania high school field, the ball would have either kicked to the right field line or stopped in the dirt sandpit at shortstop..
Angels complete a bounce pass double play The sun was in second baseman Oswald Peraza's eyes, so the third baseman Vaughn Grissom gave him a bounce pass

Funny enough, Johnny Manziel was drafted in the 28th round in 2014
I miss when the MLB Draft was 50 rounds and by the 30th round teams would just start doing bits and making irony picks.

Here's something that'll mess with your head... 2026 MLB data: In hitter's counts, pitchers have a 91% success rate (foul, called strike, BIP out, whiff, or K) in the zone... In pitcher's counts? 88% Weird, right? Pitchers are more successful when they're behind. Even counts? 92% success The Truth: you have the advantage in every single count. The number barely moves What actually changes is damage. HR% gets cut in half when you're ahead. Hitters make more contact, but it's weak Don't overcomplicate it. Because you will make a good pitch, and still give up hits. You'll make a bad one, and still get outs Just execute. Giving up hits was never in your control anyway

I see 6 things I've heard coaches say you should never do in your delivery. Misiorowski does all of them.. What do you see?

This is a big lesson for young pitchers!! Just because a pitch “worked in the lab” doesn’t mean it’s ready for the game. Bullpens are controlled. Games are chaotic. Execution under stress exposes everything... command, shape, conviction. Your stuff can look better in bullpens… or worse. But it will probably be different. Don’t lose what makes you great. Bravo to Crochet & the Red Sox for keeping the main thing the main thing... ..makes it a little easier to make that decision when you've got stuff like this – at Nashville, TN
Garrett Crochet says he’s ditching the splitter he worked on this spring: “In spring, toying with the splitter, today it was like, ‘Hey, I’m banging the splitter for the year.’ I’ll just go back to the changeup I was throwing last year.” (via @jcmccaffrey)

Connor Fennell punches out 40% (D1 top 1%) with an 88 mph FB.. but why??? 4.5 release height (top 4%) 6.7 extension (top 4%) -4.31 FB in zone VAA (top 1%) Velocity isn't the separator.. leverage & deception are Another factor -> he acts like he throws 100.. ZERO fear

You mean this thing? ... good luck hitters
A new, minor twist for Garrett Crochet this season: His changeup (which he threw just 4% of the time last year) is now more of a splitter, thanks to a new grip he learned at Vanderbilt over the offseason.

PSA for all my analytical pitchers: your fastball will not look the same every time. The baseball isn't perfect. Conditions aren't perfect. Don't get flustered by profile variance. If the best pitcher in the world has fastball variance... you will too!

Not necessarily true.. we had 10 of 11 returning or transfer pitchers who had an increase in average velo & max velo last season compared to the previous. I would argue most of our freshmen PR'd as well. No objective data for that though
Replying to @TylerHerb
That may be true but not many guys are gaining velo at Vandy they already are throwing 92-97 in order to walk into the clubhouse

There are a lot of ways to throw 95+ Figure out what works for you. Move mass fast.. no need to overcomplicate it. Guys who throw hard aren't feeling through positions.. they're violently, athletically moving through them.

The importance of seam orientation: - Same thought - Same hand finger pressure - Same intent Different grip & seam orientation -> completely different pitch profiles

If your slider is moving more horizontal than it used to, you didn't lose feel for the pitch.. you accidentally (or intentionally 👀) changed your grip.

Building an Arsenal 🧵 Don't just collect pitches to look good in a lab 🗑️ Skenes, Skubal, Yamamoto, Crochet for reference ⬇️

CB / Sweeper Your bigger breaking ball should (typically) mirror your fastball shape - North/South arsenal -> Curveball - East/West arsenal -> Sweeper

Final thoughts: - Arsenals aren't one size fits all - Your pitch package exists to help weaponize yourself against RHH & LHH Keep the main thing the main thing: throw your best stuff, execute, & get hitters out
