Back in the day, Daniil Medvedev would go out for a late night and get up just hoping everything would be OK when he picked up the racket. Turns out, that was good practice for an Australian Open campaign where he was still playing his second-round match until almost 4 a.m. on Friday and had to prepare for a big third-round match against Felix Auger-Aliassime on Saturday. “When I was very young, maybe till 21, I was going out,” he said, recounting his youth after beating Auger-Aliassime in straight sets.
