Scoring Framework
Every swing is evaluated across 7 sequential phases, each scored on 4 biomechanical sub-metrics. AI-powered analysis combined with elite coaching expertise produces a single composite score out of 70.
Each sub-metric is rated on a 5-point scale from 0.5 to 2.5. Four sub-metrics per phase means each phase is scored out of 10.

4
Sub-metrics per phase — each scored 0.5 to 2.5. The sum gives a phase total out of 10.
7
Phases per swing — from Starting Position through Extension. Each phase contributes equally.
70
Maximum composite score— 7 phases × 10 points each. This single number is your Swing Signature Score.
Each phase represents a key moment in the swing sequence. Every sub-metric has a specific biomechanical definition that guides the AI analysis and coaching review.
4 sub-metrics · scored out of 10
How evenly the hitter's weight is spread between both feet at setup. Ideal is 50/50 to slight-back (60/40) with knees inside the feet for an athletic base.
Minimal head movement during the stance. A quiet head keeps the eyes level and locked on the pitcher, improving pitch recognition and timing.
Absence of tension in the hands, wrists, and forearms at setup. Relaxed hands allow faster bat speed and smoother swing initiation.
The hitter's pre-pitch rhythm and load timing. A small, repeatable gather move that syncs with the pitcher's delivery window.
4 sub-metrics · scored out of 10
How far the back hip coils inward during the load phase. Deeper hip load stores more rotational energy for the swing.
Maintaining a stable spine angle and athletic posture throughout the gather. No collapsing, leaning, or standing up.
Ability to resist premature forward weight shift during the load. The front side stays closed and the center of mass stays back.
How much time the hitter has between completing the gather and needing to commit to the swing. More margin = better pitch selection.
4 sub-metrics · scored out of 10
When the front heel lands relative to the pitch arrival. Early plant gives more time to adjust; late plant rushes the swing.
How well the upper body stays closed while the lower body begins to fire. This separation creates elastic energy for bat speed.
The hands remain near the back shoulder as the stride foot lands. Premature hand drift forward leaks power and shortens the swing path.
The head remains still and centered over the body's base during the stride and launch. Keeps the eyes tracking the ball accurately.
4 sub-metrics · scored out of 10
The knob of the bat leads toward the inside of the ball, creating a tight hand path. Prevents casting and produces line drives.
How deep (close to the body) the barrel enters the hitting zone. A deeper entry allows the hitter to cover more of the plate.
How long the barrel stays on the plane of the incoming pitch. A longer on-plane path increases margin for timing errors.
The chest stays closed as the hips rotate, creating separation. The chest fires late, adding whip-like acceleration to the barrel.
4 sub-metrics · scored out of 10
The front hip clears out of the way so the hands and barrel have a clean path to the ball. Poor clearance blocks the swing.
The barrel stays behind the hands deep into the swing, creating lag. This stores energy that is released explosively at contact.
The proper order of energy transfer: hips → torso → arms → hands → barrel. Each segment accelerates the next like a whip.
The hitter's ability to maintain consistent bat lag across multiple swings. Consistency indicates a grooved, reliable swing pattern.
4 sub-metrics · scored out of 10
Maintaining bend in the back knee and a strong spine angle at the moment of contact. Prevents pulling off the ball.
The front leg braces and firms up at contact, creating a solid axis for rotation. A soft front side leaks energy.
The barrel stays on the pitch plane through the contact zone rather than rolling over or cutting under the ball.
The arms stay connected and don't fully extend until after contact. Early extension causes the barrel to sweep and lose power.
4 sub-metrics · scored out of 10
The bat extends toward the pitcher (or intended hit direction) after contact, not around the body. Indicates efficient energy transfer.
Both arms work together through extension with the barrel driving through the ball. Disconnected arms reduce power and control.
The hitter's weight has fully transferred from back side to front side by the finish of the swing. Incomplete transfer leaves power on the table.
The ability to achieve full extension even on off-speed or breaking pitches. Shows the hitter can adjust mid-swing without sacrificing mechanics.
