Jack Draper vs Gabriel Diallo: AI Prediction | Games, Spread, Aces & Double Faults

The model’s edge for Draper comes mainly from his recent results at this level and a better fit to grass: recent-record-by-level and surface-fit together contribute nearly 19 percentage points to his advantage. Draper arrives with two straight wins at Eastbourne (both in straight sets, 90 and 85 minutes) and a higher Elo (1789.5) that points to greater underlying strength relative to Diallo (Elo 1583.9). Draper’s form index (37.1) is also ahead of Diallo’s (31.8), and his surface strength index is marginally higher (27.7 vs 22.5), which the model rewarded. Serve and return metrics further tilt the contest toward Draper. While their mean serve indices are very close (98.2 vs 96.8), Draper’s mean return index is substantially better (95.7 vs 86.0), a difference greater than 5 points that reinforces his ability to pressure opponents’ service games even on quick grass. Fatigue is another tangible factor: Draper has accumulated 175 minutes this week versus Diallo’s heavy 335 minutes, with Diallo’s two earlier wins stretched to 158 and 177 minutes — longer matches that feed into the model’s assessment of endurance and recovery. Both players’ recent three-match form shows resilience: Draper beat Pinnington Jones and Giron in straight sets on grass then lost on clay, while Diallo converted two tough three-set wins at Eastbourne before a prior loss to de Minaur.
