The 24-year-old Australian, who stands 6’4” and weighs just shy of 15 stone, was competing at a second-tier tournament, the ATP Challenger event in Busan, South Korea, when he thundered a 163.4mph serve (263kph) past opponent Uladzimir Ignatik of Belarus.
Groth’s monstrous serving display included another measured at 157.5mph, and a third at 158.9mph – each faster than anything ever recorded on the ATP Tour.
The previous record was held by Ivo Karlovic, who sent down a 156mph serve during a Davis Cup tie between his native Croatia and Germany in 2011.
