Double up: Alex de Minaur makes the Washington quarters
Washington: Australia’s Alex has secured a place in the Washington Open quarter-finals after winning twice on the same day.
The 19-year-old defeated South Korean eighth seed Hyeon Chung 6-2, 4-6, 6-2 in a match lasting close to two hours. Earlier, de Minaur overpowered American Steve Johnson 6-4, 7-5.
Fellow Australian James Duckworth was bundled out after falling in straight sets to Stefanos Tsitsipas.
The world No.654 went down to the 10th-seeded Greek 6-3, 6-4 in just over an hour.
German brothers Alexander and Mischa Zverev faced each other in at ATP main-draw match for the first time, with No.1 seed and defending champion Alexander winning 6-3, 7-5.
Alexander Zverev advances to the quarter-finals where he’ll face Japan’s Kei Nishikori.
The brothers had met twice before in qualifying matches, most recently in 2014.
Their match ended with a lengthy embrace with Mischa saying despite the loss it was a contest he would always remember.
‘‘After the coin toss I had tears in my eyes because it felt so special,’’ he said. ‘‘I wondered what are my parents thinking right now. I needed a few seconds to bite my tongue and focus.’’
The brothers’ moment as adversaries didn’t last long.
They headed to a different court and backed up for a 6-1 6-4 win over Oliver Marach and Mate Pavic.
In other action in the US capital, Wimbledon semi-finalist John Isner was beaten by the lower-ranked Noah Rubin.
A weary-looking Isner was broken twice in the opening set to lose 6-4 7-6 (8-6) to Rubin, ranked 152nd in the world.
Isner was coming off a title in Atlanta last week while Rubin will now meet Russian Andrey Rublev in the next round.
■ Australia’s Ajla Tomljanovic has advanced to the quarter-finals of the Silicon Valley Classic after rallying to defeat Poland’s Magdelena Frech in three sets.
The world No.64 took the opening set then dropped the second before prevailing 6-4, 3-6, 6-3 in a match that lasted more than two hours.
The 25-year-old will face Romanian fifth seed Mihaela Buzarnescu in the final eight.
Tomljanovic was originally scheduled to face defending champion Madison Keys in the second round until the American was forced to withdraw due to pain in her right wrist.
The hard-hitting 23-year-old, runner-up at last year’s US Open where she lost to fellow American Sloane Stephens, is ranked No.12 in the world and was the second seed in San Jose.
