Felix Auger-Aliassime survived an early scare to reach the Estoril Open quarter-finals with victory over Carlos Taberner on Thursday.
The top seed is targeting a second title of 2022, having already triumphed in Rotterdam earlier in the campaign.
However, his quest looked in doubt when Taberner dominated the opening set 6-1.
But the world number 10 responded in equally commanding fashion; controlling the next two sets to prevail a 1-6 6-2 6-2 victor.
Auger-Aliassime, who also overcame Taberner in Barcelona last week, will play Sebastian Korda in the last eight after the American beat Benjamin Bonzi 6-3 6-3.
Meanwhile, Santiago finalist Sebastian Baez is through to his third quarter-final of 2022. The world number 59 recovered from a set down to deny third seed Marin Cilic 1-6 6-1 6-4.
Richard Gasquet awaits after the 2015 champion beat Hugo Dellien 7-6 (7-5) 6-2.
Over in Munich, second seed Casper Ruud took a while to find his groove before overcoming Slovakia's Alex Molcan 3-6 6-4 6-4.
Following Alexander Zverev's exit on Wednesday, the Norwegian is the highest remaining seed and is targeting a second title of the season having triumphed in Buenos Aires two months ago.
Next up for him is Botic van de Zandschulp, who won 86 per cent of his points on first serve as he defeated Egor Gerasimov 6-2 6-3.
Meanwhile, Oscar Otte stunned third seed Reilly Opelka 7-6 (7-4) 6-2 to reach his second quarter-final in as many weeks, having also reached that stage in Belgrade.
The German will play Cordoba runner-up Alejandro Tabilo, who advanced following the retirement of opponent Hugo Gaston through injury.
