Adolfo Daniel Vallejo vs Emilio Nava: AI Prediction | Games, Spread, Aces & Double Faults

Nava enters with the higher ranking (79 vs 106) and a substantially stronger Elo (689.97 vs 443.39), signaling a performance gap in recent head-to-head metrics. Vallejo shows a better form index (51.58) than Nava (38.17) and arrives having won his last three matches at this event, but his cumulative fatigue is large (309 minutes on court) compared with Nava’s relatively light 86 minutes. Vallejo’s surface strength index is 3.00 versus Nava’s 5.83 — both low on the same proprietary scale, but Nava’s numbers are modestly superior. Serve and return profiles diverge sharply: Nava’s mean serve index is 97.52 compared with Vallejo’s 39.91, a difference well over 5 points and likely to influence service holds and free points. Nava also has a stronger mean return index (86.28 vs 68.61), another gap above 5 points that suggests he can capitalize on return opportunities. Vallejo’s recent results show resilience on clay — three wins including a long 166-minute match — while Nava’s form is mixed (a straight-sets win in Santiago following two earlier losses), indicating a player who can produce high peaks but has been inconsistent.
