Daniil Medvedev did not travel an easy path to the biggest title of his career at the ATP Finals: He beat No. 3 Dominic Thiem for the championship after earlier getting past No. 1 Novak Djokovic and No. 2 Rafael Nadal.

By switching tactics and coming back for a 4-6, 7-6 (2), 6-4 victory over US Open champion Thiem in Sunday's final, No. 4 Medvedev became the first player to defeat each of the men ranked 1-3 in the season-ending championship—and only the fourth to do so at any tour event since 1990. "Means a lot," said Medvedev. "Shows what I'm capable of when I'm playing good, when I'm feeling good mentally, physically. So I know what I'm capable of. Just need to produce it more and more."
