Because junior tennis players have to enforce the rules of the game against each other, cheating to give a player an unfair advantage is common. While this deviant behavior is found to be commonplace in the sport, there is little research to investigate its cause or influences. Results indicated that junior players felt that personal and parental pressures were the most common sources of perceived pressure to win that resulted in cheating behavior. The prevalence of parents who cheat was also cited as a major issue with the participants. Implications as to how the current study adds to the literature of youth cheating as well as practical implications are discussed. (Contains 1 figure.)
