ABSTRACT:
A tennis ball whose weight is preferably equal to the weight of a conventional or regulation tennis ball and whose diameter is from about 2.800 inches to about 3.500 inches, the ball thus being larger in diameter than a conventional ball so as to encounter increased air resistance during flight, thereby to slow the pace of a game being played with the ball relative to the pace of a game being played with a conventional ball of smaller diameter.
