ATLANTA — Second-seeded Nick Kyrgios of Australia advanced to the BB&T Atlanta Open quarterfinals on Thursday night, beating American Jared Donaldson 7-6 (4), 6-3 in a rain-interrupted match.

Kyrgios won an indoor event in Marseille, France, in February for his lone tour title. He will face fifth-seeded Fernando Verdasco of Spain, a 6-1, 6-3 winner over France's Julien Benneteau.

Japan's Yoshihito Nishioka and Argentina's Horacio Zeballos set up a quarterfinal in the day session. Nishioka beat fourth-seeded Alexandr Dolgopolov of the Ukraine 6-3, 2-6, 6-1, and Zeballos topped Germany's Tobias Kamke 6-1, 6-4.

On Wednesday, three-time defendiing champion John Isner overpowered France's Adrian Mannarino 6-4, 6-0 to set up an all-American quarterfinal against eighth-seeded Taylor Fritz. The 6-foot-10 Isner, a former University of Georgia star, has reached the finals in Atlanta five of the previous six years.

In the other quarterfinal, seventh-seeded Donald Young will play fellow American Reilly Opelka. The 18-year-old Opelka is 6-foot-11.
