Carlos Alcaraz reached his first quarterfinal on grass as the world No. 2 crushed Jiri Lehecka in the Wimbledon warm-up event at Queen's Club on Thursday.

Alcaraz is competing at Queen's for the first time and the Spanish star is gradually finding his footing on the lawns of west London.

The 20-year-old routed Lehecka 6-2, 6-3 as he improved on a labored first round win over Arthur Rinderknech.

Alcaraz won the US Open last year and reached the French Open semifinals earlier in June, losing to eventual champion Novak Djokovic on the Paris clay.

Yet to go past the Wimbledon Last 16, Alcaraz believes he is making strides at just the right time, with the All England Club tournament starting on 3 July.

"I'll enjoy my first quarterfinal, it's a beautiful place to play and I'm enjoying every second here," Alcaraz said.

"It's more practice and I am happy getting experience on grass. After this match the expectation changes. I think I'm ready to get a good result on grass."

Top seeded Alcaraz will face former Queen's champion Grigor Dimitrov in the quarter-finals on Friday after the Bulgarian defeated Francisco Cerundolo 6-3, 7-5.

Andy Murray's first round conqueror Alex De Minaur defeated Diego Schwartzman 6-2, 6-2 to book a quarter-final against France's Adrian Mannarino, who beat Taylor Fritz 6-4, 7-6 (9/7).

British No. 1 Cameron Norrie meets American Sebastian Korda in the Last Eight.

Norrie will have plenty of attention as the last Briton in the tournament, but the 27-year-old said he would not enjoy the unrelenting spotlight of the recent Netflix tennis documentary Break Point.

Nick Kyrgios, Matteo Berrettini and Fritz were among the players followed by the Break Point cameras.

"For me, it's more important to keep training as hard as I can and to be known for being a tennis player and a good competitor," Norrie said.
