Top-seeded Stefanos Tsitsipas dismissed Argentina’s Guido Andreozzi 6-3, 6-4 on Wednesday to earn his first tour victory of the season at the Sydney International in Australia.
The 20-year-old rising star from Greece broke Andreozzi three times and held off a late comeback bid to reach the quarterfinals, where he will face Andreas Seppi of Italy. The eighth-seeded Seppi defeated Slovakian Martin Klizan 7-6 (2), 6-2.
Three other seeded players advanced Wednesday, with No. 3 Diego Schwartzman of Argentina defeating Spain’s Guillermo Garcia-Lopez 6-2, 6-3; No. 4 Gilles Simon of France outlasting Sam Querrey 7-6 (5), 6-7 (6), 6-4; and 19-year-old Alex de Minaur of Australia, the No. 5 seed, surviving 17 aces to beat American Reilly Opelka 6-4, 7-6 (5).
Brisbane native John Millman knocked off seventh-seeded Marton Fucsovics of Hungary 6-3, 6-4. Other winners were Japan’s Yoshihito Nishioka and Australia’s Jordan Thompson.
Taylor Fritz, ranked No. 50 in the world, upset top-seeded fellow American John Isner 7-6 (3), 7-6 (5) on Wednesday to reach the quarterfinals in Auckland, New Zealand.
“John’s beaten me twice before,” Fritz said. “I really wanted to get the win on him. I knew I could. We had a lot of close points, and it just feels really good to get through that.”
By withstanding 26 aces and keeping his cool in the tiebreakers, the 21-year-old Fritz advanced to face British wild card Cameron Norrie. Norrie, who grew up in Auckland, had the crowd behind him during a 7-6 (5), 6-4 victory against Portugal’s Joao Sousa.
Other winners Wednesday included No. 2 seed Fabio Fognini of Italy, as well as No. 4 seed Pablo Carreno Busta of Spain, who advanced when countryman David Ferrer retired in the first set with a calf injury. Isner wasn’t the only top seed to fall, as American Tennys Sandgren cruised to a 6-3, 6-3 win against third-seeded Italian Marco Cecchinato.
