Gabriel Diallo vs Lorenzo Sonego: AI Prediction | Games, Spread, Aces & Double Faults

The model’s edge for Diallo comes mainly from recent results at comparable levels (a +6.3 percentage-point swing) and an age-related advantage (+4.3 pp), with smaller contributions from serve/return metrics and recent form. Diallo’s form index (42.95) slightly edges Sonego’s (40.67), and his Elo sits at 1619.95 versus Sonego’s 1626.27 — a marginal Elo gap that doesn’t overturn Diallo’s momentum. Both players show identical tournament fatigue (174 minutes on court). Surface strength indices are close (Diallo 23.94, Sonego 22.00), yet the explainability output still assigns a 3.5 pp surface fit boost to Sonego. Serve/return dynamics tilt to Diallo: his mean serve index (97.47) is marginally above Sonego’s (96.01), while his mean return index (92.36) is meaningfully higher than Sonego’s 85.75 — a >5-point gap that helps explain the model’s +2.8 pp in Diallo’s favour for serve & return. Over their last three matches Diallo has two wins (including a five-set victory at Wimbledon over Bonzi) and one loss to Jack Draper; Sonego also has two wins (including a straight-set win at Wimbledon) and a loss to Kecmanovic. Those recent results contribute to the model’s modest recent-form edge (+2.4 pp) for Diallo.
