#3. 128.3 mph by Serena Williams
Serena Williams is not only regarded to be one of the greatest exponents of the sport but also the greatest server in Women’s tennis history. While it is really difficult to tell which shot Serena has mastered the most, her powerful and accurate serve has always been one of her biggest weapons and has always fascinated the spectators.
Williams’ fastest serve was recorded at 128.3 mph (206.4 km/h) during her third round match against Japan’s Ayumi Morita at the 2013 Australian Open which Williams won comfortably in straight sets. However, her path was cut short in the quarter-finals as she lost to compatriot Sloane Stephens.
Nevertheless, her 128.3 mph serve at that tournament was the fastest of the year and remains to be the third-fastest Women’s serve of all-time.
