Daniil Medvedev won the men's singles final at the U.S. Open on Wednesday, the hottest day of the tournament. He expressed concern about the extreme heat, saying “The only thing that is a little bit, let’s call it dangerous, is that the question is: How far could we go?” Medvedev's victory marks the first time a Russian man has won the U.S. Open since Marat Safin in 2000 and he will face Dominic Thiem in the semifinals on Friday.
