Daniil Medvedev credited his ability to "block out the noise" as crucial in getting his ATP Finals campaign up and running with a straight-sets victory over Alex de Minaur.
Medvedev, who lost his opening game of the tournament to Taylor Fritz, returned to winning ways with a 6-2 6-4 triumph over the Australian in 78 minutes on Tuesday.
The Russian cut a frustrated figure in his defeat to Fritz on Sunday, breaking his racket and was docked a point after serving a third consecutive double fault during the encounter.
However, the fourth seed produced an expertly measured performance, winning 20 out of 31 baseline points in the opening set to claim the early advantage.
The second set was more evenly contested, but Medvedev secured a crucial break point in the ninth game, going on to seal his first top 10 win on hard courts since March.
"After the last match I was too tired to fight mentally the way I do and so, during the match, when it doesn't work your way, you want to win and when you start losing you get frustrated," Medvedev said.
"So I went into this match thinking, if I lose I go home on Thursday for sure and if I win then I have the chance to have a good feeling. I tried to hit some shots and it worked well and I'm ok with it.
"A lot of football players do it [block the noise]. It's more about social media and for sure after my performance with Taylor and some of my comments ... I tried to read it less.
"I went into this match trying to block the noise even from myself, so no tantrums and I really didn't care what was happening on the court."
Medvedev will seek to bolster his hopes of progressing from the John Newcombe Group when he takes on Jannik Sinner next, with the Italian in action against Fritz later on Tuesday.
Data Debrief: Cool, calm and collected
Medvedev kept his hopes of sealing a second ATP Finals crown alive with a composed display against De Minaur, improving his record to 45-19 for the season.
While the Russian produced more unforced errors (18) than De Minaur (15), Medvedev showed his quality by hitting 24 winners, 14 of which came with his forehand.
Medvedev also claimed his sixth top 10 win of 2024, while also improving his head-to-head record against his Australian opponent to 7-3, avenging his defeat in the French Open round of 16 earlier this year.
