Medvedev wins!
Daniil Medvedev wins the match 4-6 7-6 (2) 6-4!
And after (fittingly) an unreturned serve, Medvedev is the 2020 Nitto ATP Finals champion! He went undefeated this week a year after going winless and he takes home the title after the longest three-set final in tournament history at 2 hours, 42 minutes.
Commiserations to Thiem, who loses in the final for the second straight year. He'll surely have many more chances at this title and is now a force to be reckoned with.
