MOSCOW — Johanna Konta of Britain upset seventh-seeded Belgian Elise Mertens in the first round of the Kremlin Cup on Tuesday.
Making up a 30-place rankings gap to the 14th-ranked Mertens, Konta took full advantage of Mertens’ wayward serving to win 6-3, 7-5.
Konta next plays Australia’s Daria Gavrilova.
French players Kristina Mladenovic and Alize Cornet and Russian veteran Vera Zvonareva all won their first-round matches.
In the first round of the men’s draw, fifth-seeded Nick Kyrgios beat Russian Andrei Rublev 6-3, 4-6, 6-4.
Belarusian qualifier Egor Gerasimov ousted sixth-seeded Damir Dzumhur – last year’s champion in Moscow – 6-1, 6-7 (5), 6-2. Another former champion, Andreas Seppi, beat eighth-seeded Martin Klizan 6-1, 7-6 (6).
STRASBOURG, France (AP) Top-seeded Ashleigh Barty withdrew from the Internationaux de Strasbourg clay-court tournament on Tuesday because of a right arm injury.
Barty was replaced in the main draw by lucky loser Diana Marcinkevica.
The eighth-ranked Australian said she would not take any risk ahead of the French Open, which starts Sunday in Paris.
“I gave it my best chance, but unfortunately I wouldn’t be playing my best tennis,” Barty said. “I’m busy the next two months and I need to look after my body now.”
GENEVA (AP) Former top-10 player Janko Tipsarevic used his wild-card entry to beat Peter Gojowczyk of Germany 7-5, 7-5 in the Geneva Open first round on Monday.
Now ranked No. 317, the 34-year-old Tipsarevic is back in ATP Tour main draws after missing the 2018 season for hamstring injuries to heal.
Fifth-seeded Radu Albot advanced to the second round on a day when two seeded players lost in the final week of clay-court warmups for the French Open.
Albot beat qualifier Lorenzo Sonego 7-6 (6), 7-6 (3), after 92nd-ranked Hugo Dellien beat eighth-seeded Andreas Seppi 6-1, 3-6, 6-4, and seventh-seeded Matthew Ebden lost to Nicolas Jarry of Chile 6-2, 7-6 (4).
Rain cut short play and gave former No. 3 Grigor Dimitrov a day off after playing through two qualifying rounds.
