What is VAA? Why does it matter? Why are there guys that can throw 92-94 up in the zone for whiffs while some throw 95-96 up and it gets crushed? Let's talk about it⬇️🧵

Excited to announce that I have taken a minor league hitting coach position with the Washington Nationals. I wanted to thank everyone @DrivelineBB for giving me an opportunity to grow in baseball. On to the next chapter.

This whole thread came out of a late night whiteboard session with our staff in AZ. Rough sketches & challenging norms. Surround yourself with coaches that push your old thinking to make you better. @brewerhendrix @cwhite23_ @Maddux_Conger @GrayLiebhardt @tykoz15

A point a farm director told us on pro FAs: Signing "facility" arms is a gamble; they don't always work on stuff to prepare them for seasonal workload.
Make sure as you "stay ready" that you ARE ready for a role assignment. Pro FAs don't have luxury of time before games!
Despite a lack of spring training, @samwhiting24 had a career year after signing with the Mariners in May🔱⬇️

"That release point is crazy" 🤯
Congratulations to Sam Whiting on signing with the @Mariners! 👏Check out his nasty four-pitch mix that led to 4 consecutive Ks in his latest Live ABs.
Sam felt great all year and didn't have arm pain once this season - big unlock for keeping him feeling fresh and available was helping him quantify/manage his workload while in gym
Another win for @DrivelinePulse

Modeling seam-shifted wake (SSW) is pretty tough - a lot more complicated than you’d think.
Fortunately at Driveline we’ve been collecting paired pitch physics data and high-speed video for about a decade.
Here’s a notable example of CH “non-Magnus maximizing” orientation.

We are 3 Months into Ian Anderson's Return to Throw off of Shoulder Surgery
Here is a look into exactly what we have done to get Ian back better than he was before and the principles being followed.

With the Padres beginning their playoff run against the Cubs tonight, we wanted to highlight Yuki's performance throughout the year and some of his off-season training. It's been great working with him and also wouldn't be possible without the help of Ike, looking forward to watching Yuki in the playoffs!

1/ Availability is the first development metric. A pitcher who isn't on the mound can't get better.
Three pro pitchers, one full season, zero IL stints. Here's how we managed their workload, why CW drove our decisions, and what it produced. 🧵

2 Interesting things to note here:
1. Great example of how seam orientation affects pitch shape if thrown the exact same way (diff between ST/CU)
2. Why is he now also throwing it harder?
-Velo generally up since '22
-Extension diff on FB/CB in 22: 5"
-Extension diff in 26: 3"
The first place I look when figuring out why guys are throwing breaking balls slower than expected is extension, for a variety of reasons:

The Marlins are running one of the most interesting side quests in baseball right now
Their best starters are also their highest-leverage relievers?
Let's talk about it 🧵
Targeting velo early allows us to hammer pitch design and learning how to get hitters out later in the offseason when it matters most
Luckily, Gabe already showed his ability to throw -8" vert splitters and 20" horizontal, just need to refine the rest of his arsenal🌪️
Since Gabe arrived @DrivelineBB :
Mound velo: 88mph ➡️ 94.9mph⛽️
Exp. Velo: 82mph ➡️ 84.5mph💪
Lower Body Power: 27 OVR ➡️ 53 OVR
Lower Body Strength: 14 OVR ➡️ 59 OVR
IMTP: 2447N ➡️ 3334N (Sheesh @ShiuNicholas)
