Maria Sharapova, Simona Halep pull out of Brisbane International

Atlanta, Jan 9: Top tennis stars like Roger Federer, Rafael Nadal, and Serena Williams will be playing an exhibition match to raise funds for Australia's bushfire relief.

Apart from these three, Naomi Osaka, Nick Kyrgios and Stefanos Tsitsipas have also confirmed their availability for the match, CNN reported.

The match will be played on January 15 at Melbourne's Rod Laver Arena. The Australian Open Rally for Relief will be donating the proceedings from the ticket sales to the bushfire relief efforts.

Tennis star Maria Sharapova had also announced on Wednesday that she had left 10 signed pairs of her tennis shoes in her Brisbane hotel that members of the public could buy with a donation to the Australian Red Cross.

"Brisbane, I have signed ten pairs of my tennis shoes, left them at the @BrisbaneTennis
desk at the Westin Hotel, alongside a donation envelope for fire rescue efforts.They're yours to keep,we just ask you to donate AUD 300 a pair. All money going directly to Red Cross," Sharapova tweeted.

Earlier, former Australian spinner Shane Warne on Monday had announced to auction his Baggy Green cap to raise funds for victims of devastating bushfires in Australia.

Taking to Twitter, Warne made the announcement and posted a statement.

"The horrific bushfires in Australia have left us all in disbelief. The impact these devastating fires are having on so many people is unthinkable and has touched us all. Lives have been lost, homes have been destroyed and over 500 million animals have died too," Warne wrote.

"Everyone is in this together and we continue to find ways to contribute and help on a daily basis. This has led me to auction my beloved baggy green cap (350) that I wore throughout my Test career," he added.

Warne joined a growing list of cricketers to raise money for the bushfire victims. Australian players Chris Lynn, Glenn Maxwell and D'Arcy Short have already announced that they will donate AUD 250 each for every six they hit in the ongoing Big Bash League (BBL) to support bushfire victims.

Athletes from other sports too joined the movement as tennis stars Maria Sharapova and Novak Djokovic decided to donate 25,000 dollars each for Australia's bushfire relief fund.

Wildfires have been raging across Australia for months, killing 23 people, burning about 6 million hectares (23,000 square miles) of bushland and killing a billion animals.

Naval and air rescue operations were launched on Friday as mass evacuations of towns at risk of being engulfed by flames got underway.b

Belgrade, June 23: Novak Djokovic tested positive for the coronavirus on Tuesday after taking part in a tennis exhibition series he organized in Serbia and Croatia.

The top-ranked Serb is the fourth player to test positive for the virus after first playing in Belgrade and then again last weekend in Zadar, Croatia.

His wife also tested positive. “The moment we arrived in Belgrade we went to be tested. My result is positive, just as Jelena's, while the results of our children are negative," Djokovic said in a statement.

Djokovic has been criticized for organizing the tournament and bringing in players from other countries amid the coronavirus pandemic.

Viktor Troicki said Tuesday that he and his pregnant wife have both been diagnosed with the virus, while Grigor Dimitrov, a three-time Grand Slam semifinalist from Bulgaria, said Sunday he tested positive.

Borna Coric played Dimitrov on Saturday in Zadar and said Monday he has also tested positive. There were no social distancing measures observed at the matches in either country and Djokovic and other players were seen hugging each other and partying in night clubs and restaurants after the matches.

 “Everything we did in the past month, we did with a pure heart and sincere intentions,” Djokovic said.

“Our tournament meant to unite and share a message of solidarity and compassion throughout the region.” Djokovic, who has previously said he was against taking a vaccine for the virus even if it became mandatory to travel, was the face behind the Adria Tour, a series of exhibition events that started in the Serbian capital and then moved to Zadar.

He left Croatia after the final was canceled and was tested in Belgrade. The statement said Djokovic was showing no symptoms.

Despite the positive test, Djokovic defended the exhibition series. “It was all born with a philanthropic idea, to direct all raised funds towards people in need and it warmed my heart to see how everybody strongly responded to this,” Djokovic said.

"We organized the tournament at the moment when the virus has weakened, believing that the conditions for hosting the Tour had been met. “Unfortunately, this virus is still present, and it is a new reality that we are still learning to cope and live with.”

Djokovic said he will remain in self-isolation for 14 days and also apologized to anyone who became infected as a result of the series. Organizers of the Adria Tour said the third stage of the event, scheduled to held next week in Bosnia, has been cancelled.
