Jannik Sinner's status as the defending Wimbledon champion and dominant world No. 1 underpins his leading 57.5% implied probability, even after an early Roland Garros exit and a deliberate choice to skip official grass warm-ups in favor of hard-court training and a late Hurlingham exhibition. Traders view his overall level and serve as decisive advantages on the surface. Novak Djokovic sits second at 11.9% due to his unmatched grass-court experience, tactical acumen, and focused schedule aimed at freshness for the fortnight despite turning 39. Early grass results from players like Alexander Zverev and Ben Shelton, combined with limited head-to-head data on the lawns this season, help explain the spread among the remaining field, where form, movement, and draw positioning shape the tighter probabilities behind the top two.
