Ghost BSBL for First Basemen
First base is a power position. Attack angle, elbow extension, and hip-shoulder separation determine whether you're carrying the lineup or leaving runs on the field.
Power hitters who underperform usually have one of two problems: a negative attack angle that turns home runs into line drives, or elbow collapse that kills barrel extension. Ghost catches both.
What Ghost watches
on your film.
Power comes from attack angle and extension together. Elbow connection is where first basemen most often lose barrel access — Ghost measures it at contact.
Up-swing at contact
Derived from hand-path velocity at exact moment of contact. Positive = up-swing. The difference between grounders and line drives.
Lead arm slot at contact
Controls bat path. Collapsing here flattens the plane and converts line drives into rollover grounders.
Coil angle at stride
Measured in the horizontal 3D plane using world coordinates. Rotational power stored before hip release.
Complete mechanics

Ghost grades all 8 pillars on every submission — not just the spotlight ones. Every angle, every phase, ranked worst fix first.

Answered.
What's costing me home run distance at first base?
Usually one of three things: negative attack angle, elbow collapse at contact, or incomplete hip-shoulder separation. Most power hitters fix one and ignore the others. Ghost grades all three from the same submission so you can stack the corrections.
What do I need to film my swing?
Any smartphone. Side angle, full body in frame — head to feet. 10–30 seconds. Slow-motion helps but isn't required. Ghost gives you exact framing instructions when you sign up.
What benchmark does Ghost use?
Every pillar is graded against pro-level mechanics — the same standard scouts and coaches use to evaluate hitters. You see exactly where your gap is and which fix closes it the most. The goal isn't to shame your numbers, it's to show you the shortest path to the next level.
