Darderi’s recent run shows two straight wins (Sebastian Baez and Pedro Martinez) before a loss to Francisco Cerundolo; his last three matches were all on clay.

Aces and Double Faults Predictions

The aces prediction for the match is 23.35 total; the predicted aces skew toward Darderi given his much higher serve index. On clay, fewer flat winners are typical, so the predicted aces remain moderated by surface conditions. The double faults prediction is 6.58 total; the expected double faults may rise during long rallies and physically demanding points on clay, and a big-serving player under pressure can contribute disproportionately to that number.

Final Prediction

Darderi’s superior Elo, form index and dominant serve/return metrics give him the clear edge in this matchup. A key factor to watch is how often Darderi’s serve converts into quick free points—if Cerundolo can neutralize the serve with returns, the dynamics could shift.
