Francisco Cerundolo vs Alexander Blockx: AI Prediction | Games, Spread, Aces & Double Faults

Cerundolo arrives as the higher-ranked player (No. 20) with an Elo of 1853.34 and a form index of 70.66. His mean serve index sits at 77.41 and his mean return index at 84.82; his surface strength on clay is moderate (45.31). Blockx, ranked 69 with an Elo of 1745.22, posts a higher recent form index (85.93) and an exceptional mean serve index of 97.61 — a gap of more than 20 points that underlines his serving firepower. Blockx’s mean return index (89.30) and surface strength (43.43) are comparable to Cerundolo’s on clay. Fatigue is a clear differentiator: Cerundolo has accumulated 174 minutes on court in Madrid versus Blockx’s 343 minutes, a factor that figures into pacing and recovery across long rallies. Over the last three matches at this event, Cerundolo has two straight-set wins in Madrid (vs. Darderi and Hanfmann) after a three-set loss to Zverev in Munich. Blockx has won three consecutive matches in Madrid — including a straight-sets win over Felix Auger-Aliassime — but those wins have come in longer matches (93–139 minutes), explaining his heavier minutes total. Both players have shown resilience, but the minutes on court tilt the freshness advantage toward Cerundolo.
