6' 8" black "Frenchman" Mpetshi Perricard serves the fastest serve ever recorded at Wimbledon at 153 mph, which is returned by American Taylor Fritz who went on to win the point.
American Roscoe Tanner used to serve in the 150s in the '70s and early '80s but is forgotten now even though he won 16 singles titles and was ranked as high as 4th in the world.
