Abstract
A practice tennis racket having a handle and peripheral frame corresponding to a conventional tennis racket. Extending across the frame is a flexible barrier net and a gridwork of yielding retaining strings. When a tennis ball is struck with the racket, the retaining strings permit the ball to pass therethrough to be caught in the net, with the strings retaining the ball in the net.
