Which tennis player has clocked the fastest tennis serve ever?”
“‘Big Bill’ Tilden, in 1931, was credited with 163.3 mph 262.8 km/h. Lester Stoefen, American also, was credited with 131 mph 211 km/h in the 1930s. In the post-war game Jack Kramer was accorded 110 mph 177 km/h and Richard Gonzales 112 mph 180 km/h.” There is some debate on these records, because of the speed measurement accuracy at that time. In modern times, the fastest tennis serve is by Andy Roddick. The current record still lies with Andy Roddick, but has increased to 155 mph, or 249.4 kph. It happened on September 27, 2004 in a Davis Cup match against Belarus. Roddick was playing Vladimir Voltchkov and the serve set him up with three match points. Needless to say, it was an ace! Some claim that Bill Tilden served up a 161 mph blast in 1915 but the record is dubious given their clocking methods at the time. Women: During her match against Barbara Schett in the second round of Wimbledon, Williams unleased a delivery clocked at 125 mph, passing the old record of 123 mph set by Bren
