Carlos Alcaraz is kicking grass…

The 20-year-old Spanish tennis phenom, the tournament’s top seed, reached his first-ever ATP semifinals on grass when he defeated former champion Grigor Dimitrov 6-4, 6-4 at the Queen’s Club Championships on Friday.

Dimitrov, the 2014 winner who came through qualifying this year, was his own worst enemy. He had a better first serve and more break chances but hurt himself with 16 unforced errors and seven double faults.

“Grigor is a top player on any surface, but especially on grass. But I played really well from the beginning to the last ball,” Alcaraz said.

“I’m a guy who learns quite fast and I’m feeling really comfortable playing on grass.”

Alcaraz also improved to 8-0 this year in quarterfinals.

In the semifinals, he’ll face Sebastian Korda, who into his first grass semifinal as well.

Korda became the first American to reach the Queen’s semis in 11 years after beating Cameron Norrie 6-4, 7-6 (1).
