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. The comeback against No. 3 Thiem, which lasted more than 2 1/2 hours, added to victories Medvedev produced against No. 1 Novak Djokovic in the round-robin portion of the tournament and No. 2 Rafael Nadal in Saturday’s semifinals on an indoor hard court without spectators, who were barred because of the coronavirus pandemic.
