Why do I get nervous when I’m playing my match? or why do I tend to get nervous on a certain shots? The reason players are insecure about a certain shot is they don’t own it. Players have not practiced the shot enough to have that shot in their pocket. Tennis shots are tools, they can use to put the ball back in play or score with. The shots that are no practiced enough will not function under pressure. The players will see you are weak on a skill and work that weak shot to win points. This builds a lack of confidence and the reason for nervous matches and shots
