ATP Tour Finals: Jannik Sinner beats Taylor Fritz, Daniil Medvedev defeats Alex de Minaur

Russia’s Medvedev, who had been booed for his antics against Fritz, put his fingers to his ears after claiming victory against De Minaur.

He dropped just nine points on his serve as he wrapped up the victory in one hour and 18 minutes.

“I went into this match blocking out the noise, even from myself,” said 2020 champion Medvedev, 28.

“I really didn’t care what happened on the pitch, I just tried to play and it was a good feeling.”

Medvedev’s temper was under scrutiny after his sullen behavior 48 hours earlier, but he struck the ball superbly and broke in the third game with a cross-court winner.

He got a double break when De Minaur double faulted, and went on to take the first set in 40 minutes.

De Minaur, 25, battled in a pulsating second set but Medvedev’s stunning backhand put him 5-4 ahead and he held serve to clinch victory.

In the doubles, Patten and Heliovaara beat Australians Max Purcell and Jordan Thompson 7-6 (7-3) 7-5 in a repeat of their Wimbledon final.

The British-Finnish duo are bidding to become the first team to win Wimbledon and the ATP Finals trophy in the same season since Mike Bryan and Jack Sock in 2018.
