Penn Control+ Tennis Balls are ideal for advanced beginning players 9 and older who play on a standard 78' tennis court. These balls reduce speeds by 25% for greater control and longer rallies. With premium, high-visibility felt for exceptional durability, the Control+ is also great for adults who require a slower-playing tennis ball. All Penn QST products are USTA- and ITF-approved and endorsed by the USPTA.
