Fastest recorded tennis serves
This article lists serving speed record breaks for the men's and women's professional tennis.
This list is not historically complete. For instance, not listed here, Roscoe Tanner's serve was clocked at 153 mph at Palm Springs in 1978 during the final against Raúl Ramírez. There are also reports that Bill Tilden had a serve that was clocked at 163.3 mph but there is nothing to verify that. Also, Ellsworth Vines in the Wimbledon finals of 1932 clocked 121 mph. Udayachand Shetty's winning serve was clocked by radar at 120 mph using a wooden racquet, at the Gilbey Gins fast serve contest held in Chicago on 24 July 1976. This qualified him to take part in the finals at the West Side Tennis Club in Forest Hills Queens on 20 August 1976.
Colin Dibley of Australia won the event with a serve of 130 mph.
Currently, the Association of Tennis Professionals does not formally recognize service speed records made in Challenger tour events due to lack of uniformity in these tournaments' radar guns. Nevertheless, the serve speed of recorded by Australian Sam Groth at an ATP Challenger event in Busan, South Korea in May 2012 was measured using ATP-approved equipment and other data gathered appeared within a normal range. However, John Isner holds the ATP's official record for the fastest serve at.
Ivo Karlović with a second serve in the quarterfinals of the 2007 Legg Mason Tennis Classic in Washington, holds the record for the fastest second serve ever recorded.
