The ‘Serve’ also formally called ‘service’ is the most fundamental aspect of tennis. The shot starts a point of the game and sets the rally in motion. A powerful service is the most important arrow in the quiver of successful tennis players. 


Mastering it becomes a considerable advantage and it is often used as an offensive weapon. From Roger Federer, who holds the record for most aces in a Grand Slam final to Serena Williams, all legends of the game have relied on the serve that is aggressive and difficult to read, reaching very high speed. The shot also gives an edge in the key moments of the match. 

Players with a fast serve are expected to win most of their service games as it provides the ability to break an opponent’s serve playing a crucial role in a match. The average speed of a ‘first serve’ in tennis is usually around the 190-200 km/h or 120 mph mark in men’s professional tennis and around the 170-180 km/h or 105 mph mark in women’s professional tennis.
