Tennis bad boy Corentin Moutet was initially told he could not retire when he tried to quit his US Open match in a bizarre ending to his first-round match.Moutet had a tough time against Australian Dane Sweeny and put an end to his struggles by retiring through injury while two sets down and 3-0 down in the third set. The previous set, he had demolished his racket in a furious outburst, earning a racket abuse penalty, and eventually decided enough was enough as he cited an injury as his reason to end the match.But in a bizarre finish, the umpire initially told him he was not able to retire as he had not yet been seen by a physio. Moutet caused confusion when he approached Sweeny to shake his hand, then shook the umpire’s hand. The umpire appeared confused and called a physio to examine the Frenchman, who then insisted he didn’t need a trainer and wanted to end the match. Corentin Moutet’s US Open game to a bizarre ending when he retired from his match Moutet was told he had to see a physio as a supervisor was called to the court Moutet had smashed his racket in a trademark outburst earlier in the matchAfter a supervisor arrived on the court and suggested an assessment would be needed to officially declare the match over, Moutet’s retirement was eventually accepted. Moutet later explained: ‘It’s my wrist, it’s been bothering me, it just won’t go away despite all the effort I’ve put in. I don’t really know what to say about it, it’s been hurting for a long time. Since Vienna last year.’The problem is that I tried to play, to push it every time. And that triggered pain elsewhere. In Cincinnati, I decided to take a break to try and put the racket down and prepare for here. ‘I worked very hard physically, without playing tennis. It was long, it was hard, and it’s frustrating not to be ready to play the last Grand Slam of the year.’Moutet has built up a bad-boy reputation after a number of emotional on-court outbursts and an expletive BBC interview that saw him fined around $40,000 before Wimbledon. ‘I never understood why you become the bad guy if you’re mad when you lose. For me, the strange guys are the ones smiling after they lose,’ he recently said on The Tennis Insider Club.’From the age of seven until I was about 16, I barely lost a match—maybe 10 a year at most. So I never learned how to lose. For a long time, that was very hard for me, because when things started going badly, I didn’t know what was happening.’The reality is that, at some point, you’re going to lose. Then you’re going to lose again, and again, and again. Nobody ever told me that.’ Moutet later discussed the injury that caused him to retire from the match while two sets down Australian wildcard Dane Sweeny has progressed after the match against the fiery FrenchmanWildcard Sweeny has joined qualifier and childhood friend Tristan Schoolkate in the second round. ‘Yeah, it’s really nice,’ Sweeny told AAP. ‘I’m always rooting for the Aussie boys and it’s nice to see a couple get over the line, especially Tristan. We’ve known each other for so long.’He left the match against Moutet with battle scars of his own, icing a lump on his elbow after the match. ‘The lump’s usually standard, but I haven’t been icing it,’ he said. ‘When I dive, I land on the same spot every time, so it just keeps popping up,’ Sweeny said.’I’ve got like permanent fluid build-up there. Sometimes I can’t help it – I’m in the air before I even know it.’
