According to the Sports & Fitness Industry Association’s 2015 Participant Report, 2.46 million Americans play pickleball. Pickleball is a paddle sport combining elements of tennis, badminton and ping-pong. The paddle is smaller than a tennis racquet, but larger than a ping-pong paddle. The plastic ball is similar to a whiffle ball and the game is played on a badminton-sized court with a slightly modified tennis net. People of all ages and skill levels play pickleball, indoors or outdoors.
