“European Open: Mariano Navone vs Tallon Griekspoor Odds: Game Spread Tallon Griekspoor -1.5 @ 55c Griekspoor won on a 3 sets from his last match, but he did 34 aces in that match. If he can keep up with his serves on this match with Mariano Navone, who prefers clay-court baseline rallies, theni think Griekspoor takes this one easy with -1.5 spread My Prediction: Game Spread Tallon Griekspoor -1.5 @ 55c https://jup.ag/prediction/POLY-1224609 #nfa”

Capture note
auto-captured: #nfa + jup.ag link + parsed side; event "European Open: Mariano Navone vs Tallon Griekspoor"; entry is the caller's stated 55¢: the order-book ask at post time read 38¢, better odds than claimed, and a call never pays more than the caller stated; entry checked against the trade tape: nothing traded inside 20s of the post; CORRECTED 2026-10-21: side was "Tallon Griekspoor -1.5 sets" (set handicap) @ 55c, now "Tallon Griekspoor -1.5 games" (game spread): the caller picked "Game Spread Tallon Griekspoor -1.5 @ 55c"; entry is the caller's stated 55¢; the order book at the post moment reads 53.5¢ (mid at post time (ask unrecoverable this long after the post)), which is not a buyable ask, so the stated figure stands (the price-history mid at the post moment, 53.5¢, is within tolerance of the claim)
