Now have you ever wondered what is up with tennis players and the noises they make when hitting the ball back and forth. Well, they have every right to make these noises. Venus Williams served the world's fastest tennis ball among women which was clocked at 56.95 m/s (127.4 mph). That's twice the speed limit on a regular highway in New York City. Tilden holds the title of World's fastest tennis ball served among men with a speed of 73.14 m/s (163.6 mph).
6 players in the womenâs draw hit a fastest serve of at least 120mph (193.1kph), while that accounted for 89 of the 94 recorded. The data shows that serve speed is not nearly as critical in the womenâs game. The fastest 30 serve speeds won 58 matches, while the slowest 30 serve speeds won 41 matches. So for the men, the bottom 30 serve speeds won only 40% of what the Top 30 achieved, while for the women the slowest 30 won 70.6% of the fastest 30.
