LONDON: Carlos Alcaraz again tested the nerves of his legions of fans on Sunday before dismissing Andrey Rublev to reach the Wimbledon quarter-finals and stay on track for a third straight title.

The Spaniard lost the first set to the Russian 14th seed under the Centre Court roof but found his feet to win 6-7 (5/7), 6-3, 6-4, 6-4, roared on by a partisan crowd.

While Alcaraz's main rivals, seven-time winner Novak Djokovic and world number one Jannik Sinner, are in ominous form, the second seed has blown hot and cold so far.

It was the same story on Sunday as he struggled to find his rhythm early in the match, despite occasional flashes of brilliance, before raising his level.

Alcaraz, who will face Britain's Cameron Norrie in the last eight, said Rublev was one of the most powerful and aggressive players on the men's tour.

think I played intelligent and smart today against him, tactically," he said. "A really good match, which I'm really proud about."

The five-time Grand Slam champion said he always believes in himself, even when facing adversity.

"Tennis is a sport that it can change just one point," he added. "One point can change the match completely, turn everything around.

"In tennis, you have to stay there all the time. Being strong mentally, to stay there. I knew that I was going to play better."

Rublev took the first set on a tie-break but Alcaraz engineered a break in the eighth game of the second set and served out to level the match.

The Russian matched his opponent blow for blow in the third set but squandered chances and Alcaraz brought the crowd to its feet with a sensational forehand winner to force a break, sealing the set with an audacious drop shot.
