An extremely bizarre incident involving a lost shoe and a wrong let call somewhat overshadowed Alexandr Dolgopolov victory over Matthew Ebden match at Melbourne Park on Wednesday.Dolgopolov lost his shoe during the deciding game of the first set and what followed was one of the more bizarre/confusing calls of the Australian Open.As you can see in the video further down, the Ukrainian's shoe came off as he started advancing towards the net to make Ebden's drop shot.Although able to return the ball back over the net, Ebden had most of the court open to hit a straightforward winner.However, the umpire initially called a let before quickly changing her mind and awarding Ebden the point as both players had continued to play the point - causing mass confusion.Having thought he would be allowed to replay the point, Dolgopolov was understandably unimpressed with the call and asked to see the supervisor – not that it mattered as Ebden’s point still stood.Meanwhile, Ebden - who surprisingly beat John Isner in the first round - was pleading his own case that the point should be awarded, claiming the shoe was a distraction."Alexandr I was wrong. I was too quick to call it a let. It's his point. You hindered yourself," British umpire Alison Hughes said.

"I don't know why she called a let, it's obstruction of play in my opinion," Ebden said after the match.

"You can't do that, if you obstruct play like that you lose the point. Bad luck. It's not like a ball falling out of your pocket that is an accident.

"She called let and I said 'what do you mean let, it's obstruction of play', and she said 'actually you are right I shouldn't have called let'.

"The Match Referee called the same thing. (Dolgopolov) didn't like it and tried to get the point replayed but you can't just leave your shoe behind and get the point played again can you?"

Eventually, play resumed Dolgopolov was able to regather his focus to secure a 7-6, 6-3, 6-4 victory and book his place in the third round, where he will face Argentine Diego Schwartzman on Friday.
