Felix Auger-Aliassime reached the semifinals of an ATP Tour event for the fifth time this season with a 6-4, 6-3 win over Botic de Zandschulp at the Stockholm Open on Thursday.

The second-seeded Canadian’s serve was the bedrock of his victory, with Auger-Aliassime hitting 11 aces and winning 27 of 33 first-service points.

“I moved well and I mixed up the ball speeds and heights,” he said. “The court suits me well here.”

Frances Tiafoe was the first player to win in the quarterfinals, rallying to beat Dan Evans 1-6, 6-1, 6-1.
