What is tennis? ~ Thurman Sims

Tennis is a sport in which players use a string-tied tennis racquet to hit a felt-covered hollow rubber ball on or around the net and into the opponent’s court. For singles, play against a single opponent (called singles) or between two teams of two players each (called doubles). The game’s object is to maneuver the ball so that the opponent cannot make a valid return. The player who cannot return the ball will not earn points, while the opposing player does.
