Buse Holds Statistical Advantages over Mannarino

Despite the final scoreline, Buse maintained statistical advantages across several major match categories against Mannarino, who entered the main draw as world No. 73 after successfully completing the qualifying rounds. According to Davis Cup captain Pablo Arraya, who analyzed the match on social media, the 22-year-old Peruvian fired nine aces to Mannarino’s two and won 39 return points compared to his opponent’s 32. Buse also captured 89 total points over the course of the afternoon, six more than Mannarino’s 83.

“Algo increíble para los que vimos el partido de Buse. Metió más saques, más aces, nueve contra dos; ganó más puntos de devoluciones, 39 contra 32; y ganó más puntos, 89 contra 83,” Arraya wrote, highlighting the rare statistical margin for a losing player.

The match turned in the second and third sets as Mannarino used his circuit experience. Although Buse recovered the service at 5-4, Mannarino broke again to take the set 7-5. In the decider, an exchange of early breaks gave way to another decisive break for Mannarino in the fifth game, allowing him to close out the match 6-4.

Fourth Straight Loss Following a Breakout 2026 Season

The Vienna exit extends a difficult stretch for Buse, who previously suffered early exits at the US Open, Beijing, and Shanghai. The skid contrasts sharply with a milestone-laden campaign that saw the young Peruvian capture the ATP 500 title in Hamburg and the ATP 250 crown in Winston-Salem, results that propelled him to a career-high ranking.

Transitioning from the Challenger circuit to regular main-draw appearances at ATP Tour events has brought heightened demands. Facing established veterans on indoor hard courts requires quick adjustments to court speed and sustained baseline consistency under pressure.

Looking Ahead to the Rolex Paris Masters

Buse’s indoor European swing is far from finished. Arraya noted that the player’s indoor schedule continues into November. Buse remains entered in the doubles draw in Vienna before shifting his focus to the final major test of the season, where Mannarino advances to meet Czech player Jakub Menšík in the second round.

The Rolex Paris Masters will run from November 2 through November 8, 2026, in Paris, France. Buse is slated to compete in both singles and doubles at the indoor hard-court Masters 1000 event, offering an immediate opportunity to reset before the 2027 calendar begins.
