Amid rain and red hue, Medvedev, Thiem advance in Australia

Impeachment trial not ready for broadcast prime time

By JOHN PYE Red dust and rain gave some of the blue courts at the Australian Open a more Roland Garros hue, adding yet another freakish element to the conditions that have plagued the season's first major.Rain on three of the first four days of the tournament has caused disruptions for players and organizers, little more than a week after smoke from bush fires caused air quality in Melbourne to be ranked among the worst in the world.Play was delayed on outside courts Thursday by showers and what a weather expert called “dirty rain” that left damp red dust covering some courts, forced the closer of some public pools and turned the Yarra River a deep, murky brown.In the three courts with retractable roofs, it was business as usual. Fourth-seeded Daniil Medvedev needed a medical timeout for a nose bleed before beating Spanish qualifier Pedro Martinez 7-5, 6-1, 6-3 and advancing to the third round.In the next match on Margaret Court Arena, 2016 Australian Open champion Angelique Kerber beat Priscilla Hon 6-3, 6-2 to complete a day session schedule that started with sixth-seeded Belinda Bencic's 7-5, 7-5 win over 2017 French Open champion Jelena Ostapenko.On Rod Laver Arena, second-seeded Karolina Pliskova, a semifinalist here last year, advanced 6-3, 6-3 win over Laura Siegemund following two-time major winner Garbine Muguruza's 6-3, 3-6, 6-3 win over Ajla Tomljanovic.Medvedev, the U.S. Open finalist, was leading 5-0 in the second set when he called the trainer to help stem the blood from his nose. He said it happens to him sometimes, he wasn't bothered too much and confirmed it wasn't related to tension.“No, no, not at all. If it would be, I would be bleeding every match I play," he said, smiling.Medvedev said shifting from outdoor conditions to indoors helped him against Martinez.“Yeah, of course it changes a lot, even like it was gray when we stepped on the court. We just played one game on the, let's say, outdoor court," he said. “As soon as the roof is closed, everything is different. It gets more hot, more humid inside. The ball goes faster. I think the sound of the ball even is different. So everything is completely different.“Today, I think it was in my advantage. Sometimes can be in your disadvantage."Bencic said she was happy to get her match out of the way early. “I didn't know the courts were, like, wet and dirty and all that,” Bencic said. “But for sure it was difficult today. It was sometimes sunny and then suddenly was almost raining. Then windy. Yeah, you just kind of have to accept it and go with it and try your best.”Melbourne Park staff used high-pressure hoses to clean court surfaces. Light rain became heavy, forcing the suspension of play on outside courts until the sun came out in the mid-afternoon. Among the big winners was CiCi Bellis, the 20-year-old Californian who is ranked 600th following four surgeries on her arm.Bellis upset No. 20-seeded Karolina Muchova. No. 19 Donna Vekic beat Alize Cornet 6-4, 6-2 and Zarina Diyas rallied to beat Anna Blinkova 4-6, 6-3, 6-4.On the men's side, Ernests Gulbis held off Aljaz Bedene 7-5, 6-3, 6-2.Organizers were again forced to postpone matches because of the weather, rescheduled seven women's and six men's first-round doubles matches to Friday. Bureau of Meteorology senior meteorologist Richard Carlyon told the Australian Broadcasting Corp. the brown rain was the result of the rain front moving through a dust storm northwest of Melbourne, and not from bushfire smoke.___More AP Tennis: https://apnews.com/apf-Tennis and https://twitter.com/AP_Sports
