Top seed Alexander Zverev produced a dominant performance to defeat Britain's Arthur Fery 6-0, 6-2 in just 58 minutes and reach the semi-finals of the Vienna Open.
The German, who is set to replace Jannik Sinner as world number one, dropped only six points on serve and converted five of nine break points against the 24-year-old qualifier.
Fery, who had upset former world number five Lorenzo Musetti in the previous round, received treatment on his leg late in that match and was not at his best against Zverev.
"I think Arthur is a bit of a different opponent than I had yesterday. He doesn't have the same firepower, but he plays tactically extremely well," Zverev said. "I know the score was 6-0 6-2, but he should not put himself down too much. It is his first year on the Tour and he is doing amazing things."
The victory was a repeat of their Wimbledon semi-final earlier this year, which Zverev also won in straight sets. Zverev is targeting his third title of the season after triumphs at the French Open and US Open, and has capitalised on injuries to Carlos Alcaraz and Sinner to become the second German man to reach the top ranking after Boris Becker in 1991.
In the last four, Zverev will face either Australian fifth seed Alex de Minaur or Italy's Matteo Berrettini. The other semi-final pits Spanish second seed Alcaraz against Russian third seed Daniil Medvedev.
Alcaraz advanced with a 6-4, 7-6 (7-2) win over American seventh seed Tommy Paul, while Medvedev secured a 6-2, 6-3 victory over France's Adrian Mannarino. Medvedev's win guarantees his place in the season-ending ATP Finals, marking his seventh appearance at the event alongside the already-qualified Zverev, Alcaraz and Ben Shelton.
Pan Pacific Open
At the Pan Pacific Open in Tokyo, world number one Elena Rybakina withdrew from her quarter-final against Leylah Fernandez due to a neck injury, one day after securing the year-end women's singles top ranking. Fernandez receives a walkover and will face Russia's Kamilla Rakhimova in the semi-finals.
