Penn Pro Marathon Extra Duty Tennis Balls are a 72-ball case built for longer-lasting play, improved visibility, and reliable bounce on hard and clay courts.
Designed for players and instructors who need consistent performance from every can, this 24-can case of Penn Pro Marathon Extra Duty balls combines Penn’s Encore Technology with high-tenacity LongPlay felt and Smart Optik color for extended life and easier tracking on the court. Each can contains three balls, and the case totals 72 balls—ideal for heavy practice schedules, clubs, or tournament warm-ups.
Penn extended the usable life of these balls by strengthening the core and using denser felt. Encore Technology improves core durability while LongPlay felt resists fuzzing, which preserves bounce and playability over more hours of hitting.
The Pro Penn Marathon uses Smart Optik felt to increase visibility against court surfaces and backgrounds. That brighter, more consistent color helps players pick up spin and trajectory sooner, especially during quick exchanges or when tracking lobs and volleys.
This listing is for one full case containing 24 tins, with three balls packed per can for a total of 72 balls. The packaging keeps cans organized for easy storage, resale by coaches, or distribution at events and practices.
Extra Duty felt is formulated to withstand abrasion from hard and clay courts while maintaining play characteristics. They are a common choice among coaches, club players, and U.S. teaching pros who need a ball that holds up through intense training sessions.
Who is this for: Penn Pro Marathon Extra Duty balls are aimed at regular players, coaches, and facilities that demand long-lasting, visible tennis balls in bulk. If you run practices, organize tournaments, or play multiple times per week and want a dependable ball that stretches your equipment budget further, this 1-case (72-ball) option provides reliable performance and fewer cans to replace.
Q: How many balls come in one case?
A: One case includes 24 cans with three balls each, for a total of 72 balls.
Q: Are these balls good for clay courts?
A: Yes—Extra Duty felt is designed to resist abrasion and performs well on clay and hard courts.
