World No. four Daniil Medvedev on Saturday claimed his first five-set victory as he defeated Filip Krajinovic 6-3, 6-3, 4-6, 3-6, 6-0 to reach the fourth round of the Australian Open for the third consecutive year. With this win, Medvedev extended his winning streak to 17 matches, which include the title at the 2020 season-ending ATP Finals. Entering this match, Medvedev was 0-6 in five-setters, including his memorable 2019 US Open championship match against Rafael Nadal. But despite letting slip a two-set advantage against Krajinovic, the Russian steadied himself to triumph after three hours and six minutes. In the third-round clash, the Russian outclassed Krajinovic in the first two sets and it almost looked like an easy encounter for the 2019 US Open finalist.
