'I don't know why I used underarm serve in Wimbledon'

'I don't know why I used underarm serve in Wimbledon'

After his 4 -- 6 6 -- 3 6 -- 2 6 -- 4 victory, Murray explained in his post-match press conference that the decision to use the uncommon shot was more often used by his friend and fellow tennis star Nick Kyrgios.

Murray's execution of the serve wasn't particularly pinpointed, with the shot too high and too long, but he won the point regardless.

Murray told reporters that he Duckworth changed his return position, and that's why I did it. He was very close to returning. He was a little bit apprehensive on the first-serve return so he stepped two meters further back. As soon as I saw him step further back, I threw the underarm underhand serve in.

I don't have any issues with players using it. More and more players are returning from further behind the baseline to give themselves an advantage to return.

The underarm serve is a way of saying : 'If you're going to step back there, then I'm going to throw that in. There seems to be a rare notion among a minority of tennis fans that the underhand serve is disrespectful to the opposing player.

I don't know why people have found it potentially disrespectful, he said. I've never understood that. 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 because they're going to track it down and it's easy to get. If they are four or five meters behind the baseline, then why would you not do that to try to bring them forward if they're not comfortable returning there? No one says it's disrespectful for someone to return from six meters, whatever, five meters behind the baseline to try to get an advantage. 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.
