Learn More About The Ace Attack

The only all-in-one serve and groundstroke ball machine

John Yandell
Tennis Researcher and Founder

“The Sports Attack ball machine is key to effective teaching. Realistic launch heights. Control of trajectory. Spins from beginner to the ATP levels. Plus the ability to serve with velocity, accuracy, and realistic spin variations. It allows teachers to be on the same side of the court with the student—in my opinion where they belong—to video, to demo, and to work directly with players on physical positions and checkpoints. I have used mine for over 15 years and can’t imagine teaching without it.”

Craig Bell
USPTA & PTR Tennis Director, Bent Tree Country Club

Bent Tree Country Club has owned our Ace Attack for 10 plus years. During that time, the Ace Attack has been a valuable teaching tool for our professional teaching staff, has provided countless hours of enjoyment for our casual players and has never missed a court opportunity as the reliability of this machine is second to none. The Ace Attack has exceeded our expectations and I couldn’t more highly recommend this ball machine if you are considering purchasing for your club or facility.”

Challenge: The return of serve is the most often hit shot in tennis after the serve; however, it is also the most under-practiced shot. So why isn’t there a single ball machine that can serve balls to help people practice their return?

Solution: Now there is! The Ace Attack is the ONLY all-in-one serving machine in tennis!
