Tallon Griekspoor vs James Duckworth: AI Prediction | Games, Spread, Aces & Double Faults

The model’s edge for Griekspoor comes mainly from his stronger recent record by level and overall strength, with additional contributions from recent form, an age-related component, and a better surface fit on grass. Those drivers align with the numbers: Griekspoor sits at world No. 60 with an Elo of 1567.09 and a form index of 26.59, while Duckworth is No. 79 with an Elo of 1465.23 and a form index of 21.40. Neither player arrives with tournament fatigue (both show 0.0 minutes on court), so freshness is a wash. Griekspoor’s surface strength index (17.85) is notably higher than Duckworth’s (8.44), which supports the model’s grass advantage for him. Serve metrics are closely matched—Griekspoor’s mean serve index is 97.58 versus Duckworth’s 95.89—so a huge serving gap isn’t expected. However Griekspoor holds a clear edge in return ability: his mean return index (91.16) exceeds Duckworth’s (84.23) by nearly seven points, a meaningful difference on a fast surface where breaking serve is at a premium. Recent form tells a similar story: Griekspoor is 1–2 across his last three grass matches (including a win over van de Zandschulp and tight losses), whereas Duckworth has struggled, going 0–3 in his most recent three grass outings.
