In the L'Open 35 de Saint-Malo WTA 125 quarterfinals on outdoor clay, No. 94 Moyuka Uchijima faces No. 151 Sofia Costoulas in their first head-to-head matchup. Uchijima, the No. 7 seed, advanced with a gritty three-set win over Ksenia Efremova in the first round before defeating Lucie Nguyen Tan 7-6(6), 5-2 in the second, building momentum after a recent Madrid first-round exit to Yulia Starodubtseva. Wild-card Costoulas upset Leolia Jeanjean in three sets to reach this stage, following a round-of-16 loss to Polona Hercog at W75 Portoroz. Uchijima's higher ranking, career-high No. 47 peak, and clay-court experience give her edge in trader consensus, though Costoulas's aggressive baseline game poses upset potential absent injury concerns or weather issues.
