Britain's Andy Murray beat Nikoloz Basilashvili in a five-set thriller on day two of the Australian Open.
Murray won 6-1, 3-6, 6-4, 6-7 (5-7), 6-4 in a match which lasted almost four hours on Tuesday.
The former British men's No. 1 had to contend with Basilashvili's monstrous forehand, and powerful baseline game, but managed to get through to book a second round tie with Japan's Taro Daniel.
Murray was playing on the same court where in 2019 he announced to the world he was contemplating retirement such was the pain in his hip, after losing in the first round to Roberto Batista Agut.
Tournament organisers at the 2019 Australian Open even played a retirement montage tribute to Murray.
But having undergone hip resurfacing surgery, three years later on John Cain Arena Murray rolled back the years after putting in a performance which married a strong serve, and brilliant defensive play to tempt Basilashvili into 99 unforced errors, compared to Murray's 46.
"It's amazing, it's been a tough three or four years," Murray said. "I've put in a lot of work to get back here and I've played on this court many times, the atmosphere is incredible.
"I've always had fantastic support and this is the one I thought I played my last match on. It's amazing to be back playing a five set battle like that, I couldn't ask for anymore.
Murray, who beat the 29-year-old in last week's Sydney Open warm-up event in a tight three-setter, said: "It was a brutal match in Sydney, we played for three hours over three sets.
"I'm sure you can tell from watching, he hits the ball huge from the back of the court, I had to do a lot of running today, a lot of defending, he's not the sort of guy you ant to see next to your name in the draw too often but yeah obviously a little bit of confidence from the win last week and managed to get over the line today.
Murray world No. 113, who has made it to five Australian Open finals, said he would like to have a deep run in Melbourne: "[I want to] keep improving hopefully, there's things in my game I can do better. I'd love to have a good reign here and have a deep run. It's something I've not had for a few years."
Elsewhere, Emma Raducanu beat American Sloane Stephens 6-0, 2-6, 6-1 in her Australian Open debut and will face Danka Kovinic in the next round.
Meanwhile fellow Brits Dan Evans and Heather Watson are also through to the second round.
Evans beat Belgium's David Goffin 6-4 6-3 6-0, and said it was a tough draw: "It wasn't the easiest of draws. Yeah, he's not played so much tennis, and I have been playing pretty good tennis, so, I mean, I wouldn't say I was confident but I was happy.
"Going onto the court, I was ready, and I didn't leave too many errors out there. I played good tennis overall, and got broke when it was, yeah, really windy. Yeah, I didn't play the best game, but I have come through and finished strong."
Watson defeated Egypt's Mayar Sherif 6-3 5-7 6-2, and said she has found her love for tennis again after a couple of difficult years: "I'm really happy to get through this one because the last couple years have not been good for me. And I had a great pre-season in Florida and I found my love and joy for tennis and competing again.
"I feel like the last couple years I felt really anxious before matches, just really not even wanting to go out there, but trying to get over it because I know in sport there's always ups and downs. Today I was excited to play. I couldn't wait to get out on the court.
"I'm happy I got through it. It wasn't my best how I have been playing, but I fought well. I feel like in the second set I lost my game plan and I found myself too far behind the baseline, but as soon as I stepped in after that first game in the third I felt really good and left the court with a really good feeling," she added.
