Double Faults
If you make all of your first serves, you will never double fault. If you only have one serve and it goes in 80% of the time, you need not worry about those few double faults. Good servers like to hit flat first serves in the corners or right at the receiver and hit topspin second serves to the receiver’s backhand. Double faults occur for various reasons. If your opponent is successfully attacking your second serve, you may be hitting it with less spin, making it faster but riskier. You may just be getting nervous. Tense muscles do not function the same as relaxed muscles, thereby sending the ball in unintended directions. A change in technique often places doubt in a server’s mind and may cause frustration and choking. The second serve should be practiced regularly so it goes in the court every time.
