Why does bat path need to be more vertical on inside pitches?
Simple, the barrel's sweet spot. Flatter paths push it farther away; vertical paths bring it closer, letting you get behind the ball and work uphill.
That's why flat paths get jammed inside, cast, and pop up more.

Jackson Holliday was once a top prospect in baseball.
Up to this point in time he hasn't lived up to expectations with a career .299 xwOBA & a .654 OPS.
Why? I believe there are 3 potential contributing factors.

I've recently been exploring the different methods that hitters use to adjust to pitches.
Here are 3 hitters manipulating their mechanics from load to downswing to create very similar mechanics in the swing phase.
Swing Phase ➡️ Full Swing

Against Misiorowski, I’m telling my hitters to sell out for the fastball up. Feel over top of everything.
These two at-bats show the challenge of getting to elevated velocity paired with a smart usage of secondary pitches.
Caminero does great here against a brutal arsenal.

Getting full-signal bat tracking data from every hitting session — whether in-gym or remote — allows us to track progress better than ever
Blast has always given metrics at impact, but now we can actually track how the barrel is moving through space
Our lab’s bat path analysis, on every swing you take at home.
In August, one of our remote hitters was clipping balls deep and hooking balls out front. His Blast swings, run through our lab’s bat path models, showed his path getting flat through the zone and working uphill too early. His coach changed his loading strategy. The next day, his bat stayed vertical through the zone about 60% longer.
You can’t get this level of insight anywhere other than Driveline Basebal

VBA & Swing Path Tilt ➡️ not the same metric.
LHH⬇️= Steep Tilt w/ flat VBA @ contact
RHH⬇️= Steep Tilt & holds line through contact
Tilt is the plane the barrel moves through 40 MS before contact while VBA is the barrel's angle measured @ contact.
Discrepancies between the two often lead to poor connection @ impact & could be a result of a hitter making last minute compensations in their swing to try & achieve flush contact.

Today's comp: XBH derby
- Extra-base hits score
- Bonus points when contact lands inside the POC range.
- One round with each speed trainer
Swing for damage with a path able to catch it at multiple POC's

I built an advanced scouting dashboard using public Statcast data to simulate preparing Tampa Bay’s lineup to face Milwaukee in the 2026 World Series.
Explore it here:

Simple constraints for bat path adjustments: pitch type, pitch location & ball flight targets.
Keeps the hitter external. Their focus stays on the pitch and the batted ball outcome.

What Driveline hitting does best is make each hitter their own best coach.
The data, drills, and cage work all matter. But the real test is what happens after the hitter leaves the building. 🧵

Some pretty ridiculous pitch locations turned into hits this postseason.
These are fun to watch, but they also make me think about how we're preparing hitters. How can we help them find the barrel when things get weird?

A few swings from the Indy Ball group this morning in FL🌴featuring the new cage cameras courtesy of @drivelinekyle.
Exit velocities over 95 mph moved them to the next bat. First to get through every bat was the winner. @_lybrookV_ took it home!

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.

Today's game: Bat Speed Wheel
The Cage Hub now features live @blastmotion bat tracking data, which allows us to score and track things like bat speed, launch angle, and smash factor in all of our games.
Here are some highlights from today's pro groups:

Why⬆️EV?
Even the lowest-output qualified hitters in MLB this year (⬇️) peaked at 102+ mph.
Raising a hitter's ceiling brings the floor along with it & creates margin for error.
High outputs are a prerequisite at the highest levels & hitters should train accordingly.

The Brewers have high bat speed (about +1 SD over league average as a team) and great squared up percentage per swing.
Milwaukee hitters swing the bat fast and have good barrel precision. CLE is the polar opposite, while BAL has elite-elite bat speed but poor barrel precision.
Jorge Arrate retweeted
Frelick's bat speed on his Game 2 HR was 7 MPH faster than his season AVG.
A good reminder that sometimes moving the bat fast isn't a can't do, but a won't do. Encourage hitters to swing fast often.
⬇️are the top 4 largest outlier bat speeds on HRs in 2026.
