Tatiana Prozorova vs Sofia Costoulas: Sofia Costoulas to win the match (+146)

Odds available at Betfair at time of publishing

Tatiana Prozorova faces Sofia Costoulas at Singapore Open on Tuesday 22 September 2026. This is a match winner bet, so it lands if Sofia Costoulas wins the match. It was priced at +146 when we wrote this, so a $10 bet returns $24.60 if it lands. Our model has this one as a long shot, so treat it as a small punt. However, Costoulas has demonstrated resilience in pressure points, achieving a better break point save percentage historically, which can be crucial in tight situations. Both players have unremarkable serve metrics, but Costoulas's ability to win points on her second serve may provide a slight advantage.

Tatiana Prozorova vs Sofia Costoulas: Under 21.5 Total Games (-105)

Odds available at BetOnline at time of publishing

The odds of -105 for the total games under 21.5 in the match between Tatiana Prozorova and Sofia Costoulas look promising. Our numbers suggest there's a good chance this total will stay low, with an expected combined score of around 20.8 games. Both players can be solid, but they might not push each other to long rallies. The closeness of their skill levels could mean quick sets, leading to fewer games than expected. Just remember, this is sports, and things can turn out differently than we hope.

Tatiana Prozorova vs Sofia Costoulas: Sofia Costoulas Set 1 Winner (+115)

Odds available at BetMGM at time of publishing

Tatiana Prozorova can be tough to beat, especially at home, but Sofia Costoulas has shown she can handle pressure. She has a good chance to win the first set, as her form has been strong lately. The biggest risk here is how close their recent matches have been, making it hard to predict a clear winner. Still, with these odds, backing Costoulas to win the first set seems like a solid choice.

Tatiana Prozorova vs Sofia Costoulas: Sofia Costoulas +3.5 Game Handicap (-143)

Odds available at Pinnacle at time of publishing

Tatiana Prozorova is a strong player, but Sofia Costoulas can really challenge her. Costoulas has shown she can keep matches close, and taking her with a +3.5 game handicap gives us some cushion. This means even if she loses, as long as she keeps the score tight, we're still in the game. The risk here is that Prozorova is a solid favorite, and she could put up a dominant performance. However, Costoulas has shown she can fight hard and take games off tough opponents. We're banking on her ability to stay competitive and keep it close enough for this bet to pay off.

That is everything our model likes in this game. Prices can move before you get on, so check the board at your bookmaker. Bet what you can afford to lose. If betting stops being fun, take a break.
