    Tatiana Prozorova Player Overview

    Tatiana Prozorova arrives at this match on the back of a poor run - she has lost three consecutive matches. Across her previous ten matches she has won five and lost five, pointing to inconsistency over that stretch. On serve, she wins just over half her service games (62%), though she double-faults frequently, averaging 4% per match. It is also worth noting that she has lost the first set in five of her last six matches, which weighs on her confidence during play. Her points-won percentage over recent matches stands at 51%, and her overall set balance is exactly even.

    Sofia Costoulas Player Overview

    In Singapore, Kostoulas came in as a replacement for the withdrawn Ekaterina Alexandrova, earning a spot in the main draw. Sofia plays an aggressive, power-based game built on heavy hitting and looking to take control of rallies early. She arrives at this match hungry for big wins and in good form. Her return and serve numbers are close to her opponent's: points won on both serve and return stand at 49%, though Kostoulas makes noticeably fewer double faults (3%). Despite a relatively modest hold percentage (21%), the Belgian takes her break-point opportunities well and has a solid set-winning record (57%).

    Key factors

    • Tatiana Prozorova has lost her last three matches.
    • Sofia Costoulas has won the first set in 70% of her last 10 matches.
    • Their head-to-head record is level, though their most recent meeting was close and went to three sets.
    • Sofia Costoulas's recent form looks more consistent.

    Expected scenario

    A tight match is expected, with a third set a real possibility. Given their previous extended encounter in Manila, another close contest looks likely, with each set potentially decided by fine margins. The bookmakers make the Russian a slight favourite, but the Belgian has the power to cause an upset if she finds her range on serve.

    ⭐ Editor's Pick

    There is no obvious class gap between these two. The Belgian player hits with more weight and aggression, which on the fast courts in Singapore should help her hold serve regularly and keep the match competitive. Even in their three-set meeting in Manila in January, Sofia Costoulas took the opening set and fought hard until the end. This looks likely to be another tight, grinding match with plenty of long games, where one or two breaks will decide it. A positive handicap can survive even a narrow defeat for Sofia in three sets, let alone a scenario where she takes full revenge. The pick is Sofia Costoulas to Win - Games Handicap +2.5.
