Norwegian second seed Casper Ruud dropped his first set before pushing back for a 3-6, 6-4, 6-4 victory over Slovakia’s Alex Molcan on Thursday in the second round of the BMW Open in Munich, Germany.

Ruud served six aces and saved five of eight break points in order to advance. In the quarterfinals he will face eighth seed Botic van de Zandschulp of the Netherlands, who was a 6-2, 6-3 winner over Belarusian Egor Gerasimov.

Third seed Reilly Opelka wasn’t as fortunate as Ruud. Germany’s Oscar Otte upset the American in straight sets, 7-6 (4), 6-2. Otte overcame Oeplka’s 10 aces by winning 32 of his 35 first-service points (91.4 percent).

Otte will face Chile’s Alejandro Tabilo in the quarters. Tabilo was ahead 6-2, 2-6, 4-1 when Frenchman Hugo Gaston retired.
