Stan Wawrinka’s conqueror Daniil Medvedev kept himself in the Wimbledon spotlight but this time it was for the wrong reasons after he threw money at an umpire’s chair.

The Russian created one of the stories of the opening day when he slayed three-time grand slam champion Wawrinka on Centre Court.

But he could not follow it up in the way he would have wanted as he was beaten in five sets on Court 16 by Belgium’s Ruben Bemelmans.

Medvedev lost 6-4 6-2 3-6 2-6 6-3, but had been 2-0 up in the deciding set before letting it slip to trail 5-2 after he became angry at the decisions of umpire Mariana Alves.

Alves docked him a point, with the Russian asking for her to be removed from her position – a request which was denied by the match supervisor.

After Bemelmans wrapped up the win, Medvedev gave the umpire a cursory handshake before taking coins out of his wallet and throwing them at the foot of Alves’ chair.

In his press conference, Medvedev issued an apology of sorts for his actions.

“I was disappointed with the result of the match,” Medvedev said.

“It was frustrating after a big win I had. All the match was not going well for me, so I was just very disappointed.

“In the heat of the moment, I did a bad thing. I apologise for this.

“It happens in the match, sometimes you are unhappy with the call. Sometimes it’s in your favour. It happens.

“I mean, as I said, I was just frustrated, so it has no meaning. I apologise for this.

“I haven’t thought about (the connotation). And that’s not why I did it. I mean, it would be really stupid. As I said, it was stupid, but it was not like this.

“Referees can make some mistakes. But me as a tennis player, I do some mistakes too. One of them was, for example, after the match. I just have to apologise.”
