Match Analysis

Jannik Sinner’s remarkable form index of 88.98 and an Elo rating of 11500 clearly showcase his prowess on the court. His surface strength index of 100.00 and a mean serve index of 97.16 provide him with a significant advantage over Duckworth, whose mean serve index is 80.43. This 16.73-point difference in serving ability could lead to a dominant serving performance from Sinner. Duckworth, on the other hand, has a form index of 61.07 and an Elo rating of 738.59, indicating a less consistent performance lately. Both players have the same cumulative fatigue level of 174.0 minutes, which could play a role in their endurance during the match. In their recent performances, Sinner has been in strong form, winning his last three matches without dropping a set, while Duckworth has struggled, winning only one out of his last three matches. Duckworth's victory came in a five-set match against Dino Prizmic, demonstrating his resilience. However, Sinner's confidence and momentum from his recent victories are likely to overwhelm Duckworth.
