Tatiana Prozorova vs Sofia Costoulas prediction

Tatiana Prozorova and Sofia Costoulas will meet for a third time when they clash in Singapore.

The head-to-head is finely-poised at 1-1 with Tatiana prevailing 4-6 6-2 6-4 in a Manila Challenger earlier this year, while Sofia came out on top 4-6 7-5 6-2 in a Dubai W100 event in 2024.

The match-up suggests there’s clear swings of momentum with little between the two and that’s the case with current ranking, form and performances at the highest level.

Costoulas is 15 places better off on the WTA ladder, but that may not count for much and it may be a wise decision to back this to go three again rather than choose the outright winner.
