Abstract: A portable tennis score keeper designed to keep the set score in the game of tennis. The set score is most often the most disputed score in the game. This invention allows any one of the players to simply flip over numbered plates to reflect the progress of each team's set score. The score keeper is simple in design, and is small enough to allow every tennis player to have it as a standard item in their sports bag. The two sets of plates suspended from notches on both sides of an elongated support member have inverse color combinations to identify each of the teams. The numbers zero through six reflects the number of games each team can win in each set. The number six is the last plate and is the total number of games required to win a set. The first numbered plate bears the word "love" inside the zero, an indicia in historical tennis score keeping terms for zero.
