Want to understand why your hitters miss underneath, top balls, or can’t square velocity?🤔
Start with contact point and learn how it affects mechanics, metrics, and ball flight.
Let’s break it down‼️🔥

- Why does Pull Air % matter? A simple but powerful stat when evaluating hitters and their ball flight⚾️ Let’s break down what Pull Air % is, why it is important, and what we can learn from 4 very different hitters‼️ MASSIVE THREAD👀🧵
- One of the first things I look at when assessing a hitter’s mechanics is their load➡️how they load their torso and pelvis. Why? Because the quality of the coil sets the tone for the kinematic chain and can directly influence bat path, sequencing, and ball flight🚀 Let’s dive in
- The lessons I learned as a hitting intern @DrivelineBB 🧠🚀⚾️ One of the most transformative experiences of my career and here’s what I learned from the best in the game🔥 MEGA THREAD🧵⬇️ Stay with me on this one it’s long… 1/17
- Put together a full 2025 offensive breakdown on Gavin Lux: swing decisions, bat path, ball flight, mechanical notes, and a full drill plan🔥👀 Deep dive on where he wins, where he can level up, and what his offseason focus should be. #Reds 1st hitting development card…✅
- Okay Max…let’s cook🔥⬇️ OPEN ANGLE (Machine) – load phase 1️⃣Offset open – flow optional 2️⃣Hook em – papi setup optional 3️⃣Step back – flow optional (45 degree step) 4️⃣Pivot pick ✅Ball flight works lower backside and can get to the pull side as barrel depth is created.best moves from today 🫰
00:00 - "Posture" in the swing has become one of the most confusing cues in coaching and can easily be misinterpreted by the athlete. “Stay down!” “Maintain your posture!” “You’re popping out of it too early!” 😵💫You’re thinking, “Do they think I slouch when I sit?” Let’s clarify
- Christian Yelich has the highest ground ball rate this season along with batted balls topped. GB%: 62.4% AIR%: 37.6% Topped%: 50.4% Yet his average attack angle is 10° which is in the ideal range (4–12°). So what is really going on? 🧵Let's break it down:
GIF - Let’s dive deeper into Pull Air %‼️ More specifically, what swing mechanics actually allow hitters to succeed when driving the ball to the pull side👀 And what mechanical breakdowns limit that ability❌ THREAD ALERT🚨🧵Why does Pull Air % matter?

- 🔑Something not talked about enough in swing mechanics: You can have great forward bend with your torso, but if the pelvis isn’t engaged, you’re leaving a ton on the table. When @CalebHadley1 pulled his pelvis away from the plate, it unlocked a ton of rotational space and
00:00 - Early morning work with @Teaganscott2026 👀 Oregon State commit and one of the top high school bats in Oregon. This was just a week before he went off at the @ACBaseballGames 🚀🧨 Session focus: coil, posture, holding space, and opening the pelvis while maintaining those
00:00 - Offset closed against a pull-side angle using our underload trainer. Goal: drive the ball in the air to the pull side without leaving rotation on the table. Cued him to “beat the ball to the spot” with his right shoulder which helped him rotate his torso fully and release the
00:00 - Working on the load phase with the Pivot Pick drill to improve coil and rotational efficiency out of that load. @GavinRoy13 had trouble clearing space to the pull side➡️turning with his chest too far over the front foot/leg. Cued him to “turn behind the front leg,” promoting a
00:00 - Some big adjustments from Brody: ✅ Learning to coil for the first time ✅ Added a hinge for better direction & plate coverage ✅ Realized “out front” isn’t the top of the plate—it’s way more Adjustments made. Results loud. Welcome to Pull Air, Brody‼️🔥 Peep the reactions
