Reilly Opelka vs Ethan Quinn: AI Prediction | Games, Spread, Aces & Double Faults

Opelka enters ranked 69 with a form index of 44.26 and an Elo of 872.47; Quinn is close in the rankings at 72 with a form index of 38.81 and a lower Elo of 822.51. Neither player carries tournament fatigue into this encounter. Surface strength indices on hard court are virtually identical (Opelka 7.48, Quinn 7.78). Serve metrics are similar — Opelka’s mean serve index is 95.77 and Quinn’s 96.38, so there’s no meaningful serve-index gap to note. By contrast, the return profile is a clear divider: Quinn’s mean return index sits at 88.30 versus Opelka’s 12.15, a large difference that will be central to how rallies develop. Recent form tells a complementary story. Opelka has two wins and one tight five-set loss in his last three hard‑court outings, including a long Australian Open match (174 minutes) versus Alejandro Davidovich Fokina and a straight-sets victory earlier in the same event. Quinn’s last three matches show one win and two straight-set defeats; his victories and losses have also come on hard courts, with recent defeats to higher-ranked opponents and a 78– to 97–minute range in match durations. These patterns underline Opelka’s marginal edge in resilience and Elo, while Quinn’s return ability could create pressure in short windows.
