Medvedev wins ATP Finals

Nearing defeat, Daniil Medvedev suddenly switched tactics at the ATP Finals and collected the biggest title of his career by beating U.S. Open champion Dominic Thiem 4-6, 7-6 (2), 6-4 on Sunday. The fourth-ranked Medvedev became the first player to beat each of the men who were Nos. 1-3 in the season-ending championship — and only the fourth to do it at any tour event in the last 30 years.

The 24-year-old Russian closed 2020 by going 10-0 in November, including seven wins against members of the Top 10.
