Carlos Alcaraz is through to the semi-finals of the Barcelona Open after defeating Australia's Alex de Minaur in straight sets 7-5 6-3.

A two-time winner of the ATP Tour 500 event in 2022 and 2023, Spaniard Alcaraz will face 20-year-old Frenchman Arthur Fils for a place in the final, after Greece's Stefanos Tsitsipas was forced to retire from their semi-final later on Friday at 2-0 down in the first set.

Denmark's Holger Rune and Karen Khachanov of Russia will contest the other semi-final ahead of the final on Sunday at the Pista Rafa Nadal, live on Sky Sports Tennis.

Rune defeated Norway's Casper Ruud 6-4 6-4 to make the last four, while Khachanov beat Spain's Alejandro Davidovich Fokina 6-4 7-5.

"I started quite badly with the serve, I was struggling a little bit mentally with it," said Alcaraz, who won 57 per cent of first-serve points in the opening set.

"It was just the first few games with my serve, then I think I improved a lot. I calmed myself down and started to think positively again.

"Alex started strong, playing aggressively, and the first set was really tight."

Alcaraz lifted his second ATP Tour title of the season in Monte-Carlo last Sunday.
