Fresh from winning the Paris Masters earlier this month, Medvedev’s number one side took part in his 4-6, 7-6 (7-2), 6-4 win in London.
The world number four had to fall behind, as he dropped the first set after being knocked out in Game 5 of the tournament.
With both players producing their best tennis when under pressure, it took time until the second set split, with Medvedev finally winning seven consecutive points to win the outstanding US Open title.
And by scoring level, Medvedev, full of energy and confidence in the third set, dominated his own service and managed to turn his third break point in the monster game, proving the difference between the two as he won the ATP Finals title.
“First of all, it’s a race. I mean, in my best win, three sets against an amazing player,” said the 24-year-old.
“Dominic, congrats for what you have achieved. Your name is in the history books of tennis.” You are playing incredible. I hope we have more matches coming up on a big occasion like this. “
Almost call too
When the ATP Finals start in London, Thiem and Medvedev may not be the two names many are expected to compete on Sunday, with long-time voting winners Novak Djokovic and Rafael Nadal.
But Thiem and Medvedev have shown why they are some of the most exciting talents as they both put on excellent performances to beat Djokovic and Nadal respectively in Saturday’s Cup.
And both have shown the strength of their service in the tournament’s open Cup, with each one outstanding during their early service games.
That was until Thiem – appeared in his second final in several years – was able to take advantage of an unchanging error from his Russian rival in Game 5 to handle the final.
And after serving, Thiem closed the first set with a set point, which was fortunate, as his hand slipped over the net and diverted the ball just enough to evade Medvedev’s set.
The second series follow a similar mold to the first, with their first effect making it too effective for the others.
With both players resolving the break point as if it looked like their opponents were about to face them, the first break and the decision of the second set came from a split.
Medvedev, who tracked the strongest match and the most net aggression, proved just too much for Thiem, comfortable to drop into the second set win with seven straight points.
The Russian, full of optimism, started the third match at the foot of the water, too, but did not benefit from the three break points he had in Thiem’s second service game.
However, he did not have to wait long to get a significant break, as in Thiem’s next service game, and on his third attempt, Medvedev managed to sew after being close to the wall.
With his continued service to prove his dominance, Medvedev won the ATP Finals for the first time in the longest final round in event history.
Thiem later said, “Of course I was disappointed, but at the same time I was proud of all the performances of the week.
“Daniil, really deserved, was a fantastic match. Congratulations on another great year. I hope we have a lot of good matches to come. It was a happy day even though I lost.”
Between appearing in last year’s US Open final and Sunday’s victory over Thiem, the Russians showed why he is one of the most promising players in the sport.
She has risen to the top of her career in tennis world rankings and could be Djokovic’s number one challenger in the world, with the next woman to win the checklist.
