Nitto ATP Finals: Casper Ruud defeats Felix Auger-Aliassime in the opening match in Turin

Casper Ruud arrived for his second appearance at the ATP Finals after disappointing performances, having won just clashes in his last four tournaments.

The 23-year-old Norwegian began the match aggressively from the get-go, firing back-to-back explosive hits to build pressure on Felix Auger-Aliassime. He maintained his rhythm in the first set tiebreak to gain a one-set advantage.

The first five points of the second set went with the service, but the no. three seed Casper Ruud raised his level in the seventh game to earn the lone breakpoint of the match to secure his victory after one hour and 51 minutes of play.

Casper Ruud served five aces, fired 21 winners, won 76% of the points on the first serve and broke the serve of his Canadian opponent one time from one opportunity. In contrast, Felix Auger-Aliassimer served 14 aces, won 84% of the points on the first serve and committed three double faults.

After the victory, Casper Ruud said, "This is some of the best levels I have played since the US Open. The last couple of months has been a struggle. I have to say that honestly, but you also have to accept it."

Casper Rudd will lock horns with Taylor Fritz in a group stage clash of the Nitto ATP Finals on November 16. He is aiming to advance to the semifinal for the second year in a row after falling to Daniil Medvedev of Russia in the semifinal last year.
