Australia’s Sam Groth famously holds the world record for the fastest tennis serve ever in a professional tournament, and his big serve was on display on the biggest stage when he faced former world number one, Roger Federer, at Wimbledon earlier this month.

Against Federer, Groth launched a serve at 236-kilometres per hour (147-miles per hour), almost 30-kilometres slower than his 2012 record serve of 263.4-kilometres per hour (163.7-miles per hour) which he sent down at the Open Challenger event in Busan.

Those behind the Hawk-Eye technology that now graces our screens so faultlessly during major tennis events decided to have a closer look at Groth’s fastest serve against Federer, with the goal of giving those at home a better idea of what it looks like to face the world’s fastest server.

The results, which you can watch in the video above, speak for themselves. With the time between Groth making contact with his serve and the ball zipping past the baseline being less than half a second, the process of returning successfully appears to become more a game of chance than skill for most non-professional tennis players.

What do you think Roarers, how would you go facing a serve from Sam Groth?
