Indian Wells star produces 'slowest ever ace serve' that puts Nick Kyrgios to shame

Fans have taken to Twitter to compare Cressy’s ace speed to that of an underarm serve, made famous in recent years by Nick Kyrgios.

“@NickKyrgios is jealous now!” one fan replied to the astounding hawkeye graphic of the 26mph ace.

Another referenced WTA former world No 5 Sara Errani, who famously once his a 49mph second serve as they joked: “Still faster than Errani’s serve!”

Former world No 12 Sabine Lisicki also commented on the slow ace, saying: “We should add this one to the service practice”.
