Nick Kyrgios - Australian Open 2023

Nick Kyrgios has ‘the best’ serve ever claims Serena Williams’ former coach

Nick Kyrgios has been credited for having ‘the best’ serve on the ATP tour by the former coach of Serena Williams, Patrick Mouratoglou.

Mouratoglou is one of the more renowned coaches on the tennis circuit and ranked his top five ATP servers in a video on Instagram.

The French coach explained why Kyrgios came out at the top of his list, “Kyrgios is No. 1 because players return much better today and he’s undoubtedly the current best.”

There is no denying that Kyrgios’ serve is a huge weapon, having fired down a total of 747 aces across 47 matches in 2022, including hitting 150 aces on his way to the Wimbledon final.

Following on from Kyrgios came the 6’10 John Isner, who hit an ATP tour leading 895 aces in 2022 and holds the all-time record for most aces with 14,186.

Isner also holds the ATP record for the fastest-ever serve at 157.2mph, and was part of the longest match in history at 11 hours and 5 minutes against Nicolas Mahut at Wimbledon in 2010.

Mouratoglou’s list was not exclusive to active players, showing the extent as to how highly he rates Kyrgios’ serve, with Andy Roddick following Isner.

Roddick was the last American man to win a Grand Slam, at the 2003 US Open, and had a serve that once hit 155mph.

“Andy had the most violent way to hit a serve in tennis history,” claimed Mouratoglou.

Ivo Karlovic sits in fourth on Mouratoglou’s ranking, which won’t come as a surprise to many, with the 6’11 Croat hitting a career total of 13,728 aces before retiring last year.

Pete Sampras took up the final spot on the list, and is the most successful player out of the five with 14 Grand Slam titles to his name.

“Pete had the most unpredictable and unreadable serve both on first and second,” said Mouratoglou.

Despite topping this list Kyrgios has not had the opportunity to utilise his serve in 2023, having not played a match due to a torn meniscus that he has since had surgery on.
