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 U.S. 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, a 24-year-old Russian. �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.�

The win against Thiem on an indoor hard court in an arena without spectators, who were barred because of the coronavirus pandemic, followed those against Djokovic in the round-robin portion of the tournament and Nadal in Saturday�s semifinals

Medvedev went 5-0 in all, quite a turnaround from a year ago, when he was 0-3 at the ATP Finals. The tournament now ends its 12-edition stay in London and heads to Turin, Italy, next year.

Medvedev closed 2020 by going 10-0 in November, including seven wins against members of the Top 10. He had zero victories over Top 10 opponents over the preceding 12 months.
