Top-seeded Stefanos Tsitsipas of Greece handled crowd favorite and wild-card Tommy Paul 6-3, 7-5 on Wednesday night to reach the quarterfinals at the Citi Open in Washington, D.C.
Paul created five opportunities to break Tsitsipas but converted just one. That break did give him a 5-3 edge in the second set, but Tsitsipas won the final four games, clinching on his third match point.
Next up for Tsitsipas will be Australia’s Jordan Thompson, who upended 14th seed Jan-Lennard Struff of Germany 6-7 (8), 6-4, 7-5.

Seventh-seeded David Goffin of Belgium fell 6-7 (5), 6-2, 7-6 (5) to Japan’s Yoshihito Nishioka, and three other seeded players also lost: Frenchman Gilles Simon (11th) and Pierre-Hugues Herbert (15th) and Australian Alex de Minaur (12th).
Canadians Milos Raonic (eighth) and Felix Auger-Aliassime (ninth) each advanced, beating Americans Tim Smyczek and Reilly Opelka, respectively.
Kevin Anderson of South Africa withdrew from the tournament due to a knee injury, continuing an injury-plagued season.
Top-seeded Dominic Thiem cruised into the quarterfinals in his home country, beating fellow Austrian Sebastian Ofner 6-3, 6-2 in 76 minutes.
Thiem faced just one break point, losing it early in the first set, but quickly answered. He hit 81 percent of his first serves, winning 80 percent (28 of 35) of them.
He’ll draw Spain’s Pablo Andujar, a 6-4, 6-4 winner over Germany’s Philipp Kohlschreiber, in the quarterfinals.
Second-seeded Dusan Lajovic couldn’t hold a lead against Frenchman Jeremy Chardy, falling 3-6, 6-4, 6-3.

No. 3 Fernando Verdasco of Spain dispatched Slovakia’s Jozef Kovalik 6-4, 7-6 (7), No. 4 Pablo Cuevas of Uruguay rallying past Austrian wild-card Dennis Novak 6-7 (1), 6-0, 6-2, and No. 7 Lorenzo Sonego of Italy surviving Spain’s Roberto Carballes Baena 2-6, 7-6 (4), 7-6 (1).
