How PROSwing Analyzes Your Swing
Professional-grade analysis based on biomechanical research
The wind-up — weight shifts to the back leg, hands set, eyes lock on the pitcher.
Target: < 2 inches drift
Think of your head as a camera on a tripod. Any drift blurs the picture. Keep your chin level and let your eyes do the work — you'll pick up spin and location earlier.
The trigger — stride begins, hips fire first, hands stay back to create torque.
Target: 45–55°
This is where power is born. Feel your belt buckle start rotating toward the pitcher while your hands stay back — that stretch across your core is the elastic energy that turns into bat speed. The more separation, the more whip.
The collision — bat meets ball, body position determines outcome quality.
Target: 65–75+ mph
At impact, your body should feel like a coiled spring releasing. Your hands drive through the zone on a slightly upward plane that matches the pitch's downward angle. Focus on meeting the ball out front — that's where barrel control lives.
The finish — full extension, balanced deceleration, evidence of efficient energy transfer.
Target: 160–180°
A long, balanced finish tells you the swing was efficient. If you're falling off the plate or cutting short, you leaked energy somewhere. Let the bat wrap naturally around your back — your body knows when the swing was right.
Each metric is scored 0-100, then combined using weighted averages into an overall grade.

Corey Seager
TEX · Lefty Power / High Load
Distinctive high-hand load creates exceptional torque. Lefty power with elite exit velocity and a violent but controlled swing path.
Bobby Witt Jr.
KC · Explosive Rotational
Elite exit velocity paired with a compact, explosive swing. Rare combination of speed and power with exceptional barrel accuracy.
Aaron Judge
NYY · Elite Power / Contact
Towering frame generates elite bat speed through massive lever length. High-efficiency swing despite its length, producing historic exit velocities.
Luis Arraez
SD · Contact Outlier
Ultimate contact baseline. Shortest swing path in Major League Baseball, maximizing barrel control to offset low raw velocity.
