In the WTA 125 L'Open 35 de Saint-Malo round of 16 on outdoor clay, Sofia Costoulas defeated Leolia Jeanjean 4-6, 7-6(1), 6-1, driving trader consensus to 100% implied probability for her victory and market resolution. Costoulas mounted a comeback from a set deficit, saving a match point in the second-set tiebreak before dominating the decider, leveraging superior stamina and clay-court baseline play against the higher-ranked Jeanjean in their head-to-head debut. With the official WTA result confirmed, the near-certain pricing reflects completed match outcome; only an improbable official appeal or scoring revision could alter resolution. Costoulas advances to face Moyuka Uchijima in the quarterfinals.
