ANDY MURRAY caught everyone napping – especially opponent James Duckworth – with a rare underarm serve during Wimbledon 2022 contest.
And we could see the same thing happen as the players battle it out at the Australian Open 2024.
Andy Murray displayed a new shot against James Duckworth
But what has Murray said about the controversial shot, and where does it stand within the rules of the sport?
Why do tennis players underarm serve?
Andy Murray says he used the shot as a “smart play” to exploit how Duckworth had changed his return position when the Brit was serving.
Murray said Duckworth had stepped two metres back so used the trick to catch him out with the serve.
The Brit said: “Well, he changed his return position – that’s why I did it.
“He was struggling a little bit on the first-serve return, so he stepped probably two meters further back. As soon as I saw him step further back, I threw the underarm serve in.
“I personally have no issue with players using it. I never have.
“It’s a legitimate way of serving. I would never use an underarm serve if someone was standing on the baseline because I think it’s a stupid idea.
“Tactically it’s a smart play.
“No one says it’s disrespectful for someone to return from 5-6 metres behind the baseline to try to get an advantage.
“So I used it not to be disrespectful to him but to say, if you’re going to step further back to return the serve to give yourself more time, then I’m going to exploit that.”
Nick Kyrgios is a fellow underarm server
What are the rules on underarm serves?
Underarm serves are perfectly legal.
As long as the ball is hit with the racquet before hitting the ground it is considered the same as hitting the ball in a downward motion.
The underarm serve was actually first deployed AGAINST Murray’s former coach Ivan Lendl at the French Open in 1989 by Michael Chang.
Nick Kyrgios and Daniil Medvedev are also proponents of the underarm serve.
