Carlos Alcaraz continued his dominant US Open form with a comprehensive victory over Jiri Lehecka to reach the semi-finals.
The Spaniard took less than two hours to beat the Czech 6-4 6-2 6-4 at Arthur Ashe Stadium in New York.
The five-time Grand Slam winner laid down an early marker by breaking world number 21 Lehecka in the opening game and never looked back.
It is the third time Alcaraz, who won the US Open in 2022, has reached the semi-finals in New York.
He has reached the last four of a Grand Slam without dropping a set for the first time in his career – and is the youngest man to do so since Rafael Nadal at the 2008 French Open.
The 25-year-old will either face fourth seed Taylor Fritz or 24-time Grand Slam champion Novak Djokovic for a place in the final.
