Australian Open 2017: Stan Wawrinka smashes ball into opponent's groin, apologises
Wawrinka's opponent Martin Klizan, who had conceded the point after a rally, was standing at the net.
Melbourne: World Number 3 Stan Wawrinka issued an apology after he smashed a ball into Martin Klizan's groin after he survived a tense five-setter to reach the second round of the Australian Open on Monday.
Wawrinka fought back from a break down in the final set to overhaul Klizan 4-6, 6-4, 7-5, 4-6, 6-4 in a match that lasted for almost three and a half hours on Margaret Court Arena.
However, there was a dramatic moment in the last set when the three-time Grand Slam champion, fired a volley at Klizan, who had conceded the point after a rally and was standing at the net.
"That was, for sure, a tough shot for him. The thing is there are some players they fake you, and you stop playing and then they just put up the racquet," Wawrinka said.
"So for me I already miss some easy ones. For me the most important thing was to run straight over to him. I just wanted to make sure he was okay. I realised he was okay."
"I'm sorry I touch him in the wrong place. But I think it was okay at the end," he added.
Klizan, the 35th ranked player, preferred not to pass judgement on his Swiss opponent but he said the latter could have hit his volley anywhere on the court.
