Il Nuovo Postiglione - Alcaraz blows past Dimitrov into Indian Wells quarters, Keys battles through

The world number three from Spain defied the difficult windy conditions on Stadium Court to deliver a dominant performance against a player who had won their past two encounters -- including in the quarter-finals at the Miami Open last year.

Alcaraz took another step in his bid to join Roger Federer and Novak Djokovic as the only men to win three straight Indian Wells titles.

Alcaraz appeared largely untroubled by the gusty winds that had ball kids scampering after blowing trash and changed the trajectories of some shots.

"Today with the conditions, it was really tough for both," he said. "I had to survive. I always say in these conditions, you have to survive no matter what. I'm very happy that I was able to play long rallies. I got a good rhythm, even with the conditions."

Alcaraz didn't face a break point until the fifth game of the second set, and worked his way out of that jam with an ace on Dimitrov's third break chance.

Alcaraz polished it off in style, giving himself a match point with his sixth ace of the match and sealing the win with a forehand winner.

He will play Argentina's Francisco Cerundolo for a place in the semi-finals. Cerundolo beat world number 10 Alex de Minaur of Australia 7-5, 6-3.

Britain's Jack Draper delivered a masterclass to stun 2022 champion Taylor Fritz 7-5, 6-4.

Draper won seven straight games to seize a 7-5, 4-0 lead over the world number four. Fritz gave him some tense moments with a late break of serve before Draper served it out on his second opportunity.

"It is the best match I have played here so far in the three years I have been here," Draper said.

Draper next faces Ben Shelton, who became the only American man in the quarter-finals with a 7-6 (8/6), 6-1 victory over compatriot Brandon Nakashima.

- Keys battles through -

The only US woman in the last eight is Australian Open champion Madison Keys, who battled past Donna Vekic 4-6, 7-6 (9/7), 6-3 to book a meeting with resurgent Belinda Bencic, who ousted third-ranked American Coco Gauff 3-6, 6-3, 6-4.

On the back foot early, Keys failed to convert a set point in the 10th game of the second set and was two points from defeat in the tiebreaker when Vekic took a 5-3 lead.

Keys gutted out the breaker and gave herself some breathing room when she broke the Croatian to open the third.

"At some point, I just felt like it was 'do or die,' probably five-all in the second-set tiebreaker," Keys said.

"I kind of just decided that I was going to go for a little bit more, and (I'm) really happy to be able to get that match and get that win and play another match here."

Bencic also had to rally to reach her first WTA 1000 quarter-final since becoming a mother last year.

She dominated Gauff to avenge a fourth-round loss to the American at the Australian Open this year.

Bencic, who was unranked when she returned to the tour in October, claimed her ninth career title in Abu Dhabi last month and has risen to 58th in the world.

She said her improving fitness was a factor in her ability to best Gauff in three sets this time, when she couldn't back in January.

"What changed is that I just kept on working also on the physical side," Bencic said. "The body is holding up much better, almost like it was before."

World number one Aryna Sabalenka of Belarus got past an early hiccup, dropping her serve in the opening game before rolling to a 6-1, 6-2 victory over British lucky loser Sonay Kartal.

Sabalenka will next face 24th-ranked Russian Liudmila Samsonova, who surprised world number six Jasmine Paolini of Italy 6-0, 6-4.
