Nelly Korda won't watch her brother Sebi in Australian Open round three...

LPGA Tour star Nelly Korda is not the only world-class athlete in her family as is being made abundantly clear in both America and Australia this week.

Nelly is competing in the Hilton Grand Vacations Tournament of Champions in Florida, while her brother Sebi is currently in the heat of battle at the Australian Open in Melbourne.

After her opening round of 68 in the first LPGA Tour event of 2023, Nelly told the media that she wouldn't be watching Sebi in his round three showdown at the Rod Laver Arena with Daniil Medvedev.

Not because she didn't want to, but because the 24-year-old is in a conflicting timezone which would require a 4 am alarm to watch her 22-year-old brother in action.

"Yeah, I’m not going to be watching. Hopefully, it’s not still going by the time I’m up. Hopefully, he’s won already. But yeah, I’m sure my parents are going to watch. They’ll be a little sleep deprived tomorrow walking 18," Nelly said on Thursday.

Sebi is seeded 29th in this year's Australian Open having turned professional in 2018. His highest world ranking is 30th and he won his first ATP title in 2021 in Parma.

A win over Medvedev would constitute a fairly big turn-up in a grand slam that has already seen the exit of the great Rafael Nadal, but also the heroic progression of Andy Murray.

You can safely assume that Korda's parents, Petr and Regina and her fellow golf star sister Jessica, will be tuning in. Petr won the Australian Open himself in 1998 and Regina also played in numerous grand slams.

It would be a pleasant surprise for Nelly to wake up to her brother booked into a 4th-round tie with 10th seed Hubert Hurkacz, but she will also be focused on winning her ninth LPGA Tour title.

She trails by one shot from 18-hole leader Brooke Henderson. Henderson won her second major title at the Evian Championship in 2022.
