An all-Spanish affair between Alejandro Davidovich-Fokina and Bernabe Zapata Miralles was an excellent contest of high-quality tennis.
His first title success came in July 2018, when he made it into the main draw of the German Open and won the tournament.
The Serbian struck 31 winners to beat Cuevas in straight sets and will play Lithuania's Ricardas Berankis next in Paris.
Both the German and the Norwegian tennis players registered straight forward victories to enter the last-8 in Munich
