Primary fix identified
Stay through the ball with a palm-up / palm-down hand position at contact and let the release happen AFTER the ball, driven by sequence rather than an early flip.

The faults
The faults that cost you most
Fault 01
Foot down late
Landing as the hands fire — hip-shoulder separation never builds.
Fault 02
Bat drag
Barrel trails the hands through the zone — late on fastballs.
Fault 03
Rolling over
Weak grounders pull-side when the ball should be driven.

Proof, not just claims
Here's a worked Baseball example on sample data — the same shape your real report takes. We show the evidence, the confidence, and what we honestly can't know.
Example diagnosis
Early top-hand roll-over: the barrel closes before contact, catching the top of the ball — a contact-point and sequence issue, not just "wrists."
Top fix: Stay through the ball with a palm-up / palm-down hand position at contact and let the release happen AFTER the ball, driven by sequence rather than an early flip.
What SwingVantage uses
- At contact the top-hand palm is already turning down (should still be up)Estimated — how to read this label
- A wrappy, around-the-body finish suggests the barrel left the zone earlyInferred — how to read this label
- Reported weak pull-side grounders match an early-roll, closed-face contactInferred — how to read this label
What it can't know
- Exact bat speed or exit velocity without a sensor/radar
- Whether it is timing vs. mechanics until we also see live pitching
- Bat fit and any physical limitations — use age-appropriate gear and stop if it hurts
How you'll measure progress
On day 7, re-film from the same open-side angle and hit 10 tee balls. Freeze at contact: is the top-hand palm up now? Chart line drives vs. grounders over the next two weeks.
Coach & parent summary
Hitter rolls over early, producing pull-side grounders. Priority: stay through the ball, release after contact. Drills: palm-up checkpoint, two-tee path, opposite-field tee work. Retest in 7 days; chart contact quality.
Your hitter is catching the top of the ball, which turns good effort into soft grounders. The plan is three simple tee drills over a week — no extra strength needed yet. Keep it positive and let them feel solid contact.
What do the confidence labels mean?
Illustrative example
Sample data, not your swing — used on demos and the sample reports so you can see the format before you start.
Heuristic estimate
A smart, data-backed read from limited input (a self-report or a single video). It is honest about being an estimate, and it sharpens every time you add a swing.
Measured
Read directly from launch-monitor or sensor data you import, or from a verified, calibrated multi-camera setup. A phone video is never labelled measured — what we read from it is an estimate.
We always show you which one you are looking at, and never present an estimate as a measurement.
Your swing, decoded — coaching in your pocket. SwingVantage reads your swing and gives you the one fix that matters most, with data-backed guidance you can use today. Its findings are estimates that get sharper with every swing you add. For injury concerns or advanced technique, pair it with a coach — you'll show up to those sessions already ahead.

Hitting Metrics SwingVantage Analyzes
All metrics are benchmarked by age group and competition level — from youth rec to professional.
Exit Velocity
Ball speed off the bat. Primary indicator of hard-hit contact quality.
Launch Angle
Vertical angle of the batted ball. 10–20° = line drives, 25–35° = home run trajectory.
Bat Speed
Barrel speed through the zone. Foundation of exit velocity.
Attack Angle
Upward swing path in degrees. Affects launch angle and ball flight.
Time to Contact
Milliseconds from first move to contact. Shorter = more time to read pitches.
On-Plane %
How often bat path matches pitch plane. Higher = more consistent contact.
Spray Angle
Pull/push tendency. Identifies pitch coverage gaps.
Distance
Projected distance of the batted ball based on exit velocity and launch angle.
What SwingVantage can and can't tell you
Every result carries the same honest label everywhere you see it — so you always know what's precise, what's an estimate, and what to trust for your next session. Our free engine does the everyday read; optional AI depth is coming later.
Measured
Read straight from your launch monitor or sensor data. The most precise number we can show.
Estimated
Our free coaching engine compares your swing to research benchmarks for your sport and level. Trustworthy direction you can train on today — no AI required.
Inferred
AI that reads your video frames is coming later — optional extra depth on top of the free read. Single-camera limits will still apply.
Self-reported
Based on what you describe yourself. Useful context, and as accurate as the details you share.
Frequently Asked Questions
- What baseball hitting metrics does SwingVantage track?
- SwingVantage tracks exit velocity, launch angle, distance, bat speed, attack angle, time to contact, hand speed, spray angle, and on-plane percentage. Data can come from HitTrax, Rapsodo, Blast Motion, Diamond Kinetics, or manual entry.
- What is a good exit velocity for high school baseball?
- A solid benchmark for high school hitters is 85–90+ mph exit velocity (EV). College-level players typically target 90–95 mph. Professional-level hitters average 92+ mph, with elite hitters exceeding 105 mph.
- What launch angle should I target in baseball?
- For consistently hard contact, most coaches target a 10–20° launch angle for line drives and hard grounders. Optimal home run launch angles are 25–35°. Anything above 40° typically results in pop-ups.
- Can SwingVantage help me fix a casting or long swing?
- Yes. SwingVantage analyzes attack angle, time to contact, and hand path to identify casting, looping, and long-to-the-ball patterns. Targeted drills address each fault.
- Is SwingVantage useful for youth baseball players?
- Yes. SwingVantage adjusts benchmarks by age and skill level. Parents and coaches can track development over time and generate age-appropriate drill progressions.

- How to Stay Inside the Baseball (Stop Casting)Staying inside the ball means leading with the hands and knob, not casting the barrel out early. Here is how to diagnose casting and groove a tight, quick path.
