Andrey Rublev made the most of Holger Rune's nerves to win a see-saw Monte Carlo final 5-7, 6-2, 7-5 on Sunday, as the Russian's talent was finally rewarded with a Masters title.

The fifth seed stayed composed when it mattered to eventually run down his 19-year-old opponent and claim the most prestigious title of his career.

Rublev, 25, was 4-1 down in the decider but ground his way back into the contest to prevail on his second match point with an ace at a sun-drenched Monte Carlo Country Club.

It was Rublev's third attempt in a Masters final after failing at the final hurdle here in Monte Carlo and in Cincinnati in 2021.

"I have tears. I don't know what to say, I'm just happy, I struggled so much to get this title," said Rublev.

Rune needed nearly three hours to beat Italian Jannik Sinner in the semi-finals.

Rublev also needed three sets to beat American Taylor Fritz, and fatigue was a factor in Sunday's showdown.
