Ben Shelton, Andrey Rublev, and Hubert Hurkacz were among the players at the Rolex Shanghai Masters last week who took part in the Wrong-Handed Serve Challenge.

The ATP 1000 tournament in Shanghai concluded on Sunday, October 15, with Hurkacz defeating Rublev in the final to win the second Masters title of his career. Multiple top players were present at the event, and while they were there, several took part in the fun serving challenge.

The task was simple - players had to serve at the highest speed they could manage with their non-dominant hand. For some players such as Shelton and Ugo Humbert, this meant serving with their right hand. However, many had to switch to their left, with American player J. J. Wolf declaring that he didn't think he had "ever hit a lefty serve before."

Some players struggled more than others, with Humbert's first attempt hilariously flying off into the empty stands. Meanwhile, World No. 12 Tommy Paul achieved the fastest speed with his left hand, reaching 71 mph.

This brought out his compatriot Wolf's competitive spirit, who reached up to 68 mph in the video.

"You guys might be out here for a while, I'm not stopping until I beat Tommy," he joked.

Elsewhere, Rublev and Hurkacz both hit 63 mph but had differing views of their success.

"It's okay, Im happy with the 63. Perfect," Rublev said.

"About the speed of my drop shots. So, not great," Hurkacz remarked upon achieving the same score.

Christopher Eubanks pulled off an impressive 66 mph and Mackenzie McDonald reached 61. Meanwhile, Zhizhen Zhang hit 50 mph and Shelton, who is known for his powerful serves, was seen hitting 56 mph with his right hand.

However, Nicolas Jarry appeared to be having the most difficulty with his left hand. Despite getting 59 mph, his second attempt went down to 48.

"I'll stick with the right hand," he concluded.
