Andy Murray believes his Davis Cup experience against Sam Groth helped him overcome the Australian in the pair's first singles match.

The British number one moved into the third round of the Australian Open by beating Groth 6-0, 6-4, 6-1 in Melbourne - taking just one hour and 30 minutes.

And the Scot explained how the Davis Cup doubles match, played with his brother Jamie Murray in September, helped prepare him for taking on the big-serving Australian in singles.

"I think it helps to see somebody’s game," the Dunblane ace explained.

"I’d never hit with him or played against him at all, apart from that match in the Davis Cup, and I was only returning from one side of the court against him.

"But it definitely helps to have been on the court against him. You see what he’s like up at the net, which side he volleys better off, which side he returns better.

"In doubles you can often get a better idea of that than in singles.

"A lot of guys return pretty well in singles because there’s more court to hit into, but in doubles, when you’re under pressure and you have to be more accurate with the return... you get a good idea of that."
