Ben Shelton vs Lorenzo Sonego: AI Prediction | Games, Spread, Aces & Double Faults

The model's edge for Shelton comes mainly from recent form (+7.1 percentage points) and overall strength (+6.6 points), with age (+3.3), recent record by level (+2.5) and overall record/opposition quality (+2.0) also nudging the prediction his way. That aligns with the raw numbers: Shelton sits at world No. 5 with an Elo of 1833.6 and a form index of 44.47, while Sonego is No. 65 with an Elo around 1584.7 and a form index of 32.47. Shelton also posts a notably higher surface strength index on grass (43.57 vs 21.58) and arrives fresher (0 minutes court time in this event) compared with Sonego’s 171 minutes, a factor on a quick surface where recovery matters. Both players bring strong serving profiles—Shelton’s mean serve index is 96.69 and Sonego’s is 95.34—so neither has a decisive serve advantage by the >5-point threshold. Shelton holds a modest edge in return index (90.06 to 86.10), which dovetails with the model’s assessment that his all-around strength and recent form are critical. Over their last three matches, Shelton is unbeaten on grass in Stuttgart (wins over Fritz, Lehecka and Shimabukuro), while Sonego’s recent slate includes a win over Jianu and losses to Basilashvili and Tommy Paul, producing a patchier run into Halle.
