What is a double fault in tennis?

In tennis, a double fault occurs when a player serves and fails to get the ball into the opponent's service box on both of their serve attempts. This results in the loss of the point and the opponent winning the point without having to hit the ball back.

Double faults are considered a costly mistake in tennis as it gives the opponent an easy point and may also result in frustration and loss of momentum for the serving player. It is common for double faults to occur when a player is under pressure, fatigued, or lacking confidence in their serve.

Players strive to avoid double faults by practicing their serve technique, staying focused during crucial points, and maintaining a consistent serving routine. Double faults can have a significant impact on the outcome of a match, particularly in close and high-stakes situations.
