San Francisco Frontiers - Sinner boosts number one bid in Paris, to face Zverev in semis

The Italian powered to a 6-3, 6-3 win over his fifth-seeded opponent and will next face Zverev, who saved two match points to beat Daniil Medvedev 2-6, 6-3, 7-6 (7/5), in Saturday's semi-finals.

Sinner, looking to take advantage of rival Carlos Alcaraz's shock second-round loss to Cameron Norrie, extended his winning streak to 24 successive matches on indoor hard courts.

Sinner will usurp Alcaraz at the top of the rankings by winning the title at the La Defense Arena.

"At the moment I'm not thinking about the ranking," he said.

"It all depends on how I'm playing. We go day by day, every day you have very difficult challenges coming up."

He has now won seven successive matches against the powerful Shelton since losing their first meeting in Shanghai in 2023.

The 24-year-old is targeting his fifth title of the season after last weekend adding the Vienna Open trophy to his Australian Open, Wimbledon and China Open triumphs from earlier in the year.

Sinner has won his last three meetings with Zverev.

"I'm happy to be in the situation where I am, tomorrow it's again a very important day but I'm looking forward to it," Sinner added.

The four-time Grand Slam champion wrapped up the first set in just 34 minutes, sealing it with a thumping baseline winner to break Shelton's serve for the second time.

A 22nd consecutive win against American opponents appeared nothing more than a formality for Sinner when he moved 3-1 up in the second set.

But Shelton immediately hit back with a break to love before levelling the set to gain a foothold in the match, much to the delight of a packed crowd.

The left-hander's revival did not last long, however, as Sinner broke again in the eighth game.

A deft winner at the net secured a place in his 13th Masters semi-final on his first match point.

Third seed Zverev kept his title defence on track after digging deep in a tense clash with former world number one Medvedev.

Medvedev raced through the first set before losing his rhythm in the second as Zverev forced a decider.

The Russian moved to the brink of victory when leading 5-4 in the third as Zverev made a series of unforced errors on his forehand, but Medvedev passed up two opportunities to secure the win.

Zverev took that momentum into the tie-break and ended a run of five successive defeats by Medvedev when his opponent fired long.

- Bublik reaches first Masters semi-final -

Earlier, Alexander Bublik battled back to defeat Alex de Minaur and reach the first Masters 1000 semi-final of his career.

The Kazakh, enjoying his best-ever year, edged a dramatic contest 6-7 (5/7), 6-4, 7-5 to set up a last-four meeting with Felix Auger-Aliassime, who saw off Valentin Vacherot in his quarter-final.

Bublik is still in the race to qualify for next month's ATP Finals in Turin, competing for the eighth and last berth with Lorenzo Musetti and Auger-Aliassime, albeit is more likely to have a chance as an alternate.

"That's definitely an important match but not probably the most important of my life. You never know. We'll see," Bublik said of his clash with Auger-Aliassime.

Auger-Aliassime cruised past surprise Shanghai Masters champion Vacherot 6-2, 6-2 to keep his hopes of qualifying for the Finals alive.

The Canadian, targeting his second Masters 1000 final appearance, holds a 3-2 winning head-to-head record over Bublik.

"He (Vacherot) is so confident and you are kind of scared to be honest," Auger-Aliassime said.

"I had to be so focused from the start and this level of intensity from the first game I brought helped ease me into the match and I played some good tennis."
