ATP Roundup: Tsitsipas and Cilic reach quarters at Citi Open; Thiem edges closer to first Generali Open title

Stefanos Tsitsipas was too good for Australian Jordan Thompson, prevailing 6-3 7-6 (7-4) to book a spot in the last eight in Washington, while world number four Dominic Thiem, who has never won his home tournament, moved into the semifinals in Kitzbuhel.

Greek star Stefanos Tsitsipas, the top seed in Washington, was too good for Australian Jordan Thompson.

Stefanos Tsitsipas advanced to the Citi Open quarterfinals and the in-form top seed was joined by Marin Cilic and Daniil Medvedev. Tsitsipas was too good for Australian Jordan Thompson, prevailing 6-3 7-6 (7-4) to book a spot in the last eight on Thursday.

Greek star Tsitsipas saved a set point in the second set as he earned a clash with 10th seed Benoit Paire in Washington. "It's very pleasing knowing that I can be mature and handle those situations very bravely, so I'm really happy with that," said Tsitsipas.

"I showed character out there. I played heroic tennis, I would say, in those crucial moments. That was very nice to see."

Paire – who fired down 12 aces and did not drop serve – defeated fifth seed John Isner 7-6 (7-3) 6-3 at the ATP 500 tournament.

Former US Open champion Cilic beat ninth seed Felix Auger-Aliassime 6-3 6-4 to reach the Washington quarters.

Auger-Aliassime's 11th double fault of the match allowed sixth seed Cilic to move through, with Medvedev waiting in the next round. Medvedev – the third seed – saw off local favourite Frances Tiafoe 6-2 7-5.

Elsewhere, eighth seed Milos Raonic was stunned 6-4 6-4 by Peter Gojowczyk, Kyle Edmund rallied past Jo-Wilfried Tsonga 4-6 6-3 6-4, Norbert Gombos trumped Miomir Kecmanovic 1-6 6-3 7-6 (7-4) and Nick Kyrgios was a 6-2 7-5 victor against Yoshihito Nishioka.

The top seed is aiming to win his home tournament for the first time and, although his match with Andujar lasted close to two hours, Thiem came out on top 7-6 (7-4) 6-4 on Thursday.

Thiem, a beaten finalist at Roland Garros earlier this year but a winner in Barcelona and at Indian Wells, excelled on the second serve and broke four times to overcome the Spaniard.

Lorenzo Sonego, who beat third seed Fernando Verdasco 6-4 6-4, awaits Thiem in the final four.

Joining Thiem and Sonego is 20-year-old Norwegian Casper Ruud, who continued his fine run with an impressive 6-3 7-6 (7-4) victory over Pablo Cuevas to reach his third ATP Tour semifinal of 2019.

Jeremy Chardy beat second seed Dusan Lajovic in the round of 16, but the Frenchman could not follow that win up against Albert Ramos-Vinolas, who triumphed 6-3 6-4 to set up a semi against Ruud.
