Key Prediction Insights

At Wimbledon in London, opening-round grass-court play pits Jan-Lennard Struff against Sebastian Baez in the Round of 128. The model favors Baez, who is given a 60.46% chance to win versus 39.54% for Struff, with an expected total of about 36.8 games in the match.

Match Analysis

The model’s edge for Baez comes mainly from age and overall strength, with age contributing the largest single shift toward him and overall comparative strength adding further weight. Those model drivers sit atop more marginal pulls toward Struff based on fatigue and serve/return metrics. Struff arrives ranked 74 with a form index of 36.81 and an Elo around 1564; he shows no tournament fatigue and carries a strong grass serve profile (surface strength index 18.80). Baez is ranked 57, with a form index of 33.27 and a slightly higher Elo (~1576); his surface strength index is lower (12.36) but overall ratings tilt the model in his direction. Serve and return indices are high for both players (Struff mean serve 96.60, return 90.94; Baez mean serve 94.89, return 89.03) so neither enjoys a clear serving supremacy by the 5-point threshold. Recent form differs: Struff has one win in his last three (a Mallorca second-round victory) but lost to Bublik and Borges on grass; Baez has struggled in his last three recorded matches, dropping results at Roland Garros, Geneva and Rome. The model still credits Baez for overall consistency and other underlying metrics despite those losses.
