The Son Test

“My son at Florida State — he’s hitting tanks.”

Gary has been teaching his kids to keep their hands connected for as long as they could swing a bat. His son is now in a Power-5 D1 program — and he trains with the 9 STRAP. If a hitter at that level uses it, your son or daughter has no business swinging without one.

“My Great Friend Ryan”

A pool guy built it. A champion co-signed it.

The “great friend” Gary mentioned on camera is Ryan Vaughn — founder of 9 STRAP. Not a coach. Not a credentialed swing guru. A pool contractor in Orange County who happened to play on Yucaipa High’s back-to-back CIF championship teams in ’93 and ’94.

On July 6, 2023, Ryan watched Corbin Carroll — then the front-runner for Rookie of the Year — nearly tear his labrum on a one-armed swing finish. He looked at his wife Alyson and said, “there has to be a way to prevent that.” Within days she was at the kitchen table stitching the first 9 STRAP out of an old Rawlings batting glove and gift-wrapping ribbon.

Why Sheffield put his name on it.

Gary’s whole career was a clinic on connected hands. The famous bat-wag. The whip through the zone. The 509 home runs. Ryan’s strap is the first piece of equipment that gives a 12-year-old the same hand position a 22-year MLB veteran spent decades drilling into muscle memory.

One swing fix — for the price of a Little League snack run.

From $39.95. Works on any glove, any brand, any size. Same-day shipping. 30-day money-back guarantee — try it for a full month of games and send it back if your swing isn’t measurably better.

Common Questions

Answers, fast.

Yes. Thousands are being used in game every day in leagues all over the country. NFHS and Little League had originally banned the product. However, after presenting a 3rd party study showing the safety aspects of the 9 STRAP, along with multiple medical and legal reviews, they immediately voted to allow it moving forward.

If you come across any official notices of the 9 STRAP not being allowed for any reason, please share it with us so that we can immediately reach out to them and share these same safety benefits for ballplayers, and ensure they are not being negligent in disallowing this amazing product. Thanks!
Simple. When you grip the bat with the 9 STRAP, your hands are locked together. When you let go, your hands are completely free and independent. That’s the beauty of it, and most likely why it’s so revolutionary and never been invented before.
If you want to continue using your existing 9 STRAP, and have the ability to remove or swap, go Compatible — your existing 9 STRAP will go on your bare hand underneath your batting glove. If you want one less thing to put on each at-bat, go Integrated — the 9 STRAP is built in.
Full Hide: thicker, stiffer — less of a distraction for newer ball players. Lite: thinner, less noticeable — for the confident, experienced ballplayer. Pro: thinnest, longest, most discreet model. No velcro and only available in adult sizes.
