BRISBANE, Australia, Jan 3, 2025 (BSS/AFP) - Former world number one Novak 
Djokovic's Australian Open preparations suffered a blow Friday as he was 
bundled out of the Brisbane International by towering American Reilly Opelka.

The 2.11 metre (six feet 11 inches) Opelka served magnificently and returned 
just as well to stun the 24-time Grand Slam winner 7-6 (8/6), 6-3.

Djokovic had gone into the tournament insisting that at 37 he still had the 
game to trouble the younger players.

But Opelka, 27, a former world number 17 who was out of the game for almost 
two years from 2022-24 following hip and wrist surgeries, dominated the Serb 
and wrapped up a comfortable win in an hour and 40 minutes.

Opelka came back to the sport in July last year but showed his serve has lost 
none of its potency in his time away.

He served 16 aces and only faced one break point throughout the match.

"He's the greatest player ever," Opelka said of Djokovic.

"The reality is we have nothing to lose coming in against him. You end up 
playing more freely and you take a lot more risks because it's your only 
chance of beating him.

"It's tough for him, because you get guys like me who are going to roll the 
dice, and on a day like this things go my way, and that's how it worked out."

Opelka now faces another huge server in the semi-finals, rising French star 
Giovanni Mpetshi Perricard, who made it 75 aces in three matches as he beat 
Czech player Jakub Mensik, 7-5, 7-6 (7/5).

- Sabalenka through -

The second semi-final will see defending champion and second seed Grigor 
Dimitrov up against another Czech, Jiri Lehecka.

In the women's semi-finals, world number one Aryna Sabalenka overpowered 
Marie Bouzkova in straight sets.

Sabalenka, who has won the last two titles at the Grand Slam in Melbourne, 
beat the Czech player 6-3, 6-4 in a tough match lasting 1hr 45mins.

She now plays Russian teenager Mirra Andreeva, who defeated Tunisia's Ons 
Jabeur 6-4, 7-6 (7/2).

The 17-year-old Andreeva showcased her rich potential by defeating former 
world number two Jabeur in a high-quality encounter.

Jabeur was runner-up at Wimbledon in 2022 and 2023 but has been out of action 
since August with a shoulder injury.

Andreeva was able to deal with the tricky shotmaking of Jabeur, breaking her 
once in the first set and then recovering from two breaks of her own serve in 
the second set to force a tiebreak.

She raced through the tiebreak to wrap up the match in 90 minutes.

"It was mentally hard to keep pushing and playing aggressively because we all 
know that she's very good at playing games -- drop shots, slices," Andreeva 
said.

The second women's semi-final will be between Russian qualifier Polina 
Kudermetova and Ukraine's Anhelina Kalinina.

The Australian Open starts on January 12.
