"He changed his return position" - Murray on using underarm serve at Wimbledon

Andy Murray surprised many by using an underarm serve at Wimbledon but he explained after the match that it was by design.

Speaking about it, Murray admitted it's a viable strategic option in certain moments of a match:

“He changed his return position. That's why I did it. He was standing very close to return [initially], 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."

The Briton deployed the tactic when serving with a 2-1 lead in the third set against the World No. 74. Duckworth scampered forward and was able to return the ball but was subsequently undone by a Murray lob. Murray added:

“I personally have no issue with players using it. I never have. Certainly, more and more players have started returning from further, further behind the baseline now to give themselves the advantage to return. The underarm serve is a way of saying, if you're going to step back there, then I'm going to possibly throw that in.”
