Tatiana Prozorova vs Sofia Costoulas Prediction Singapore Tennis Open - Singapore · Sep 22, 2026

Analysis

The little form data we have tilts towards Sofia Costoulas, who won back-to-back matches against Jennifer Ruggeri on 25 and 26 August, both in straight sets (2-0). Tatiana Prozorova arrives from a 1-2 defeat to Kristina Liutova on 25 August, a match she at least took a set from, so her level was competitive rather than overwhelmed. Both are young, aggressive baseliners whose games travel reasonably well to a hard-court event, and Singapore's heat and humidity tend to slow the ball and reward whoever is more patient in longer rallies. Costoulas has the momentum and the sharper recent result, but the margin is modest and a first-round meeting between two players without a shared history is inherently volatile. With no head-to-head on record, neither has a tactical read on the other, which usually means a scratchy start and a match decided late.
