Daniil Medvedev had an angry run-in with a courtside TV camera as he missed out on a place in the final of the Western & Southern Open in Cincinnati. The top seed was a set ahead against fellow Russian Andrey Rublev when he ran into a camera during a rally. Clearly annoyed at its positioning on the court, Medvedev shoved the lens with his foot before complaining to the umpire that he “could have broken my hand”. The right-hander, who is ranked second in the world, needed a medical time-out for treatment on his left hand. Whether it inhibited him was unclear, but fourth seed Rublev took advantage to gain a first career win over his compatriot, prevailing 2-6, 6-3, 6-3. In the women’s event, Jil Teichmann’s remarkable run continued as she reached the final. The Swiss wildcard, who had already beaten the world No 2, Naomi Osaka, and the Olympic champion, Belinda Bencic, saw off Karolina Pliskova, the Wimbledon runner-up, 6-2 6-4. She said on court: “It’s tough to explain, but when I ask my coaches what they think of me they say you’re an unexpected person who does random things. I guess this is one of them. I’m feeling really good, serving good, moving well. I cannot even describe it.” Teichmann, the world No 76, will face Ashleigh Barty in the final after ensuring there would be no repeat of last month’s Wimbledon showpiece. Barty, the SW19 champion, defeated Angelique Kerber in straight sets to reach her sixth final of the year. Barty swept aside Germany’s Kerber 6-2, 7-5 in one hour and 14 minutes to extend her 2021 record to 39 wins and seven losses – a WTA Tour-leading number of victories.
