Andy Murray fought back from a set down to book his place in the third round of the US Open for the first time since 2016.
The 35-year-old Brit, who famously sealed the first of his three Grand Slam titles in New York 10 years ago, didn't have it all his own way as he eventually defeated American Emilio Nava 5-7, 6-3, 6-1, 6-0. The inexperienced Nava - aged just 20 and ranked 203 in the world - defied expectations at the start of the match as the pair engaged in one of the most gruelling first sets ever seen at the US Open.
Following the mammoth set that lasted an hour and 24 minutes, it was the young American who eventually took the crucial break to take the opener 7-5 in front of the crowd at Arthur Ashe stadium. His performance and shots led to plenty of praise from commentators and fans alike but it was Murray who seized the initiative from then on.
