Raphael Collignon vs Ben Shelton: AI Prediction | Games, Spread, Aces & Double Faults

Shelton arrives with a clear edge in raw ratings: a 1829.64 Elo and a top-10 ranking versus Collignon’s 1638.29 Elo and No. 64 placement. Collignon’s recent form index (49.66) is higher than Shelton’s (35.70), indicating sharper results in the short term, but overall pedigree and Elo favour Shelton. Both players carry identical tournament fatigue (174 minutes), so stamina coming into this contest should be comparable on paper. Surface strength indexes differ: Collignon’s clay score is modest at 13.56 while Shelton’s is better at 31.52, suggesting Shelton adapts to clay more effectively despite neither being a clay specialist. Return and serve profiles matter here. Mean serve indices are virtually identical (Collignon 95.79, Shelton 95.84), so there’s no significant serving advantage to note. Collignon, however, holds a noticeably stronger mean return index (92.84) than Shelton (84.94) — a gap greater than five points — which could transform a few key service games, especially on a slow clay court where returns have more time to develop. Over the last three matches Collignon has two wins (including a straight-sets Roland Garros opener) and a loss to a higher-ranked clay player; Shelton also opened with a straight-sets win, surrounding that with a hard-fought loss and a previous victory, showing some inconsistency but high ceiling.
