Tennis is a game where the players have to move fast in many cases. Unlike other games, you can't just stand there while playing tennis. There are many instances where players need to run or move fast even when they are not hitting the ball. Here are some players who are known for their speed on the court.

5 Fastest Tennis Players in the World

Mardy Fish

The 6'4" American professional tennis player is known for his speed on the court. His quickness is due to his excellent footwork which he attributes to his time playing soccer while growing up. Mardy's ability to get from one side of the court to another quickly means that he can get to balls that some other players can't. Fish is a former 2008 US Open quarterfinalist and a two-time semifinalist at the 2008 Delray Beach International Tennis Championships and 2012 Sydney International, as well as a five-time singles titlist on the ATP Tour.
