Down and out in Paris, de Minaur still dreams of Finals

Alex de Minaur's bid to win the Paris Masters is over, his hopes shattered in another physically gruelling battle with tough young Dane Holger Rune.

Jordan Thompson's first appearance in a Masters 1000 quarter-final also ended in disappointment as a partisan crowd cheered home his French conqueror Ugo Humbert in Bercy on Friday night (Saturday AEDT).

The duo had been only the second Australian men's pair in the last 20 years to get to the last-eight of the singles in the same Masters event after Alexei Popyrin and Max Purcell in Cincinnati last year.

But just as his hopes up the road at Roland Garros in the French Open had been ended at the quarter-final stage earlier in the year, de Minaur again bowed out at the same point in the French capital 6-4 4-6 7-5 after an engrossing two-hour 25-minute slugfest with Rune, a player who shares his fighting qualities.

But, ultimately, the 21-year-old Dane saved his best for last in the dying stages of Friday's absorbing contest to set up a semi-final with Alexander Zverev, the German who had ended de Minaur's quest at the French Open.

The silver lining for de Minaur may still yet be a coveted first-time place in the ATP Finals in Turin later in November.

For the Australian No.1 departs the tournament provisionally still holding onto the eighth and final place for the Finals in Turin, while still knowing there's a danger he could yet be surpassed by his chasers in the final furlong of the race over the next nine days.

Later in the evening, Thompson, in uncharted waters after reaching a Masters quarter-final for the first time in 28 attempts stretching back seven years, cut a lonely figure as the Paris crowd again went crazy for the wild-eyed Humbert, still on a high after stunning Carlos Alcaraz 24 hours earlier.

The dashing left-hander overcame an injured foot and a stirring late rally from the 30-year-old Thompson to power through 6-2 7-6 (7-4) while being helped by 23 winners.

Earlier, Zverev, who's already guaranteed a place in Turin, had advanced to the semis by beating Stefanos Tsitsipas 7-5 6-4, in the process killing off the Greek's last faint hopes of making the Finals.
