Holger Rune has been scolded by his racket sponsor Babolat for trying to sell his broken equipment online. The No. 8 seed, who lost in the opening round against Nicolas Jarry on Monday, was selling a smashed racket for over £5,000 on his own website.

The online shop also had unbroken rackets available for £4,300, along with various items of kit. The website claims that profits will go to charities, with many of the items also signed.

However, Babalot are fuming that their damaged rackets, which were broken during furious outbursts on court, are being flogged.

"It is not our intention to promote broken rackets," Tennis Business Leader at Babolat, Marion Cornu, told CLAY.

"We are in talks with his agent. Obviously, it is not our intention to promote broken rackets. We must be consistent with our values, so we are working on this issue with his representatives."

A statement on Shop Holger Rune reads: "Holger Rune's smashed rackets are ultra-rare collector's items, used in official matches and only available in very limited numbers. Why? Because Holger rarely lets frustration take over. But when he does, the moment - and the racket - tells a story."

Rune was extremely bitter after throwing away a two-set lead to be dumped out of Wimbledon in the first round.

He talked down his opponent Jarry, saying: "I'm beating him nine out of ten times, with all respect for Nicolas Jarry. Obviously today didn't make it a lot easier with my knee, but yeah, it was not great."

He added: "I think I started all right in the match playing well. Then third set, a bit unlucky. Fourth set I started to feel my knee and then got some treatment. Yeah, never was able to serve and hit my backhand as I was, you know, able to do in the first two sets.

"I've had it before. I have not had it for a long time. I don't know. I know what it is, and especially being extremely low on the grass, it can bother that area. You know, obviously didn't expect it to come back, but that can happen, yeah."
