If he wasn't on the court competing, Daniil Medvedev doubted anything would have kept him at Rod Laver Arena until almost 4 in the morning. The third-seeded Medvedev lost the first two sets of his second-round Australian Open match against No. 53-ranked Emil Ruusuvuori before coming back to win 3-6, 6-7 (1), 6-4, 7-6 (1), 6-0 in 4 hours, 23 minutes in the latest finish of the week. The match ended at 3:39 a.m. Friday, and Medvedev was still there signing autographs as the clock ticked closer to 4.
