US Open 2017: Rafael Nadal's next opponent, Alexandr Dolgopolov, quizzed by TIU over August match

NEW YORK: Rafael Nadal's next opponent at the US Open is a 28-year-old from Ukraine who is being asked questions about a different tournament entirely — one where he was involved in a match under scrutiny from anti-corruption investigators because of unusual betting.Alexandr Dolgopolov moved into the fourth round at Flushing Meadows for the first time since 2011 with a victory on Saturday. Dolgopolov, who is ranked 64th, said after his 6-1, 6-0, 6-4 win against Viktor Troicki that he has been interviewed by the Tennis Integrity Unit.[caption id="attachment_3992893" align="alignleft" width="380"]

I don't ask. They asked me about some information. They interviewed me. That's it. That's all I can do."As for what effect the whole episode has had on him, Dolgopolov said: "Not much. You can see I'm playing. I'm fit. I'm doing well. Obviously it's disappointing, but not more. If people want to write something, they write something. You can't stop them from doing it. It's just not under my control."TIU spokesman Mark Harrison said this week that the group "was made aware of concerns over betting patterns" during the match between Dolgopolov and Monteiro. The match is being assessed but is not yet under formal investigation, Harrison said, noting that many reasons other than corruption can explain unusual gambling patterns.Dolgopolov certainly has looked good on court at the US Open.He beat 2010 Wimbledon finalist Tomas Berdych in the second round, then needed just over an hour to eliminate Troicki in the third.Dolgopolov's best Grand Slam showing was a run to the Australian Open quarter-finals in 2011. Later that season, he lost to Novak Djokovic in the fourth round in New York.Now comes the spotlight associated with a match against the top-seeded Rafael Nadal, whose 15 Grand Slam titles include two at Flushing Meadows. Nadal advanced on Saturday night by beating Leonardo Mayer 6-7 (3), 6-3, 6-1, 6-4 with the Arthur Ashe Stadium roof closed because it was raining."I'm not a young player anymore," Dolgopolov said. "I don't think I'm going to get intimidated by the No. 1 player or the stadium or the occasion."
