San Francisco Frontiers - Sinner and Zverev march into Paris Masters last eight

A maiden crown in the French capital will return Sinner to number one in the world rankings after current incumbent Carlos Alcaraz suffered a shock early exit at the hands of Britain's Cameron Norrie.

The Italian four-time Grand Slam champion is yet to drop a set in the tournament as he hones in on what would be a fifth title of the season.

"Today I felt like the first set was very crucial. Francisco is a very talented player, it's very difficult to play against him because his level is very high," Sinner said on-court.

"In the second set I raised the level... and I'm very happy to be in the quarter-finals here for the first time."

Sinner edged a close first set, which featured four consecutive breaks, when he pounced on 21st-ranked Argentinian Cerundolo's serve at 6-5 to seize the initiative.

The 24-year-old then immediately stepped it up in the second set, racing into a 5-1 lead before serving out to book a meeting with US fifth seed Shelton in Friday's quarter-finals.

Shelton beat Russia's Andrey Rublev 7-6 (8/6), 6-3 to reach the last eight.

The victory marked another landmark moment for the 23-year-old this season -- following on from his first 1000-level title, won in Toronto this summer -- as he will make his debut appearance at the ATP Finals in Turin.

"It's an accumulation of a year's work, a lot of ups-and-downs, great results, poor results and having to bounce back," Shelton said of reaching the season-ending event.

- 'A miracle' -

Zverev continued his title defence with a 6-2, 6-4 win over Spanish 15th seed Davidovich Fokina in the day's final match-up.

The German third seed will next meet an old foe in former world number one Daniil Medvedev, who fought past Lorenzo Sonego of Italy in three sets.

Zverev and Medvedev have met twice before in the Paris Masters, with the now-11th seeded Russian winning on both occasions, including the title-match in 2020.

Earlier, Alexander Bublik of Kazakhstan beat US fourth seed Taylor Fritz 7-6 (7/5), 6-2 to set up a last-eight clash with Australian world number six Alex de Minaur.

Despite arguably being in the form of his life in 2025, 13th seed Bublik said it would require something miraculous for him to win a career-first Masters title.

"I have three matches to go, I have to beat the top ten players, maybe Jannik (Sinner) in the final, so that sounds a bit like a miracle," the 28-year-old said.

Bublik's next opponent, De Minaur, eased past Russian 10th seed Karen Khachanov 6-2, 6-2, and in the process cemented his place at next month's ATP Finals.

Canada's Felix Auger-Aliassime reached the quarter-finals as he came from behind for the third time in as many matches in Paris to beat German Daniel Altmaier 3-6, 6-3, 6-2.

The ninth seed is one spot outside the last ATP Finals berth, which is currently occupied by Lorenzo Musetti, who lost Wednesday to Sonego.

That result coupled with an Auger-Aliassime charge to the title-decider in Paris would send the 25-year-old above the Italian in the race to the eight-man showpiece.

However, before he can think too much about that, Auger-Aliassime must stop the in-form Valentin Vacherot of Monaco.

The Shanghai Masters champion continued his sensational run by ousting Norrie in straight sets in the opening match on centre court.
