Andy Murray has jokingly admitted he might regret a diving volley during his epic five-set win against Matteo Berrettini because of his metal hip. 

The veteran Scot, 35, beat the World No 13 Italian in a titanic tussle in the Australian Open first round, edging past his opponent 6-3, 6-3, 4-6, 6-7, 7-6, in four hours and 49 minutes after a tense tie-break.

And when asked by former British star Tim Henman if a man with his injury history should be trying diving volleys on a hard court, Murray said he would find out later.

He said: 'I'll probably find out tonight or tomorrow whether that was the right move. But I was so close to the finish line there, I probably should have made the volley. It feels alright just now, but let's see in a few hours.

'It felt like we were playing really good tennis, I'm not sure what it looked like. He was serving unbelievable, he was serving brilliantly and he is one of the best competitors on the tour. I did well to get through. I had a couple of break points early in the first set and didn't get them. 

'The momentum changed after that. I made a couple of little tweaks right at the end of the fifth set, maybe I could have changed things earlier. I'll be feeling this, this evening and tomorrow. But right now I am unbelievably happy and very proud of myself. 

'I've put a lot of work into the last few months with my team to give me the opportunity to perform on stadiums like this and in matches like this. It paid off tonight.'

The 2021 Wimbledon finalist Berrettini was the superior player for the last three sets, but Murray held his nerve in the sudden death 'Champions' tiebreak to take it 10-6. He will play Fabio Fognini or Australia's Thanasi Kokkinakis in the second round.

This was Murray's best performance at a Grand Slam since the onset of his hip problems and he now has a piece of metal in the affected area. He was always ahead in the tie-break, racing into a 5-0 lead before being pegged back but eventually getting over the line.
