Alex de Minaur’s quest to reach the ATP Finals for the first time may have suffered a fatal blow at the hands of mercurial French magician Hugo Gaston, who conjured up one of the shots of the tennis year while mesmerising the Australian number one in Antwerp.

Antwerp top seed de Minaur missed out on a golden opportunity to gain valuable points in his bid to be one of the top eight men’s players who qualify for the season-ending championship in Turin, starting on November 10.

Novak Djokovic’s trip to the Shanghai Masters final bumped de Minaur down to ninth, leaving the Australian with work to do to reach the event for the first time.

The door had been left ajar for de Minaur to gain points on Andrey Rublev, currently eighth in the ‘Race to Turin’ standings, as the Russian top seed was knocked out of the quarterfinals of the Nordic Open in Stockholm 7-6(7/5), 7-6 (7/5) by the ageless Stan Wawrinka.

De Minaur could have closed the gap by reaching the semifinals at the European Open in Antwerp against 77th-ranked Frenchman Gaston, who had never beaten a top-10 player before.

But Gaston, who also defeated de Minaur at a fiery French Open match in 2022 when the Aussie complained about a raucous Roland Garros crowd “going over the line” in support of the maverick home favourite, again defied the odds — and injury — and a hugely entertaining quarterfinal.

Although needing a second-set medical timeout for what seemed to be a groin injury and never moving easily after that, Gaston still uncorked some fizzing shots to defy a rusty de Minaur, who was playing in only his second tournament in three months since his injury-hit Wimbledon.

Nothing topped the glorious moment in the opening set when southpaw Gaston raced back to retrieve a near-perfect de Minaur lob and somehow, with back to the court, whipped a blind winner from over his shoulder past the astonished Aussie, who could only applaud.

De Minaur looked hot favourite in the deciding set as Gaston hobbled around between points but he somehow raised his game, sealing only his second break in the final game with a fabulous backhand winner down the line to prevail 6-3, 3-6, 7-5 after two hours nine minutes.

De Minaur will look to make up ground at the Vienna Open next week, heading into the Paris Masters the week after.

Earlier, at the Almaty Open in Kazakhstan, fellow Australian Aleksandar Vukic knocked out American top seed Tiafoe 6-2, 7-6(13/11), prevailing in a dramatic tiebreak during which he let four match points slip while saving two set points of his own.

“Pretty overwhelmed, that tiebreak was pretty crazy,” beamed the Australian world number 85.

“We were both a little bit nervous and the crowd was really getting into it, the atmosphere was great. I guess this is what it’s all about, you don’t feel emotions like this anywhere else. Happy to get through and go again tomorrow.”

In his third ATP semi-final, Vukic will face Russian Karen Khachanov in the last four, and he knows just how to prepare.

“Might go to the driving range next door to our hotel, unleash some balls to get some emotion out of me,” Vukic said.
