Andy Murray did the unthinkable on Thursday night - early hours of Friday, to be exact - beating Thanasi Kokkinakis in a five-set marathon in the second round of the 2023 Australian Open. The feat will be talked about for years.The former World No. 1, playing his second straight five-setter of the tournament, went toe-to-toe with the young Australian for five hours and 45 minutes, making it the longest match of his career.Murray also overturned a two-set deficit in the process, claiming his 11th victory on tour after overcoming the loss of the first two sets -- another ATP record he claimed with his Melbourne Park magic. In the end, the 35-year-old prevailed with a 4-6. 6(4)-7, 7-6(5), 6-3, 7-5 scoreline, sealing a comeback win for the ages.The Brit's display on the night made his fans eternally grateful, as they immediately flocked to social media to sing his praises. No superlatives were held back on the occasion, as users on Twitter thought of every possible way to salute the three-time Grand Slam champion for his heroics.One fan remarked that no one in the history of sports will ever come close to matching the Brit in terms of mental acumen and perseverance, noting:"Not to be dramatic but we will never see anyone like Andy Murray ever again in sport. Ever."Rush 🐠@drivevolleysnot to be dramatic but we will never see anyone like Andy Murray ever again in sport.
