Qualifier Martina Okalova will seek to keep her strong debut in Sao Paulo going when she takes on Janice Tjen this Wednesday. This is their first career meeting, and the winner will advance to the quarter-finals. Read on for our prediction of this match.
Janice Tjen was in dominant form in her opener against seventh seed Leolia Jeanjean and lost just five games. The win marked her second-ever victory in the main draw of a tour event.
Tjen, who won her first tour match at the just-concluded US Open, has now recorded 60 victories in 71 matches in 2025. A winner of six ITF titles this season, the 23-year-old has moved up seven places to 123rd in the live ranking.
Martina Okalova defeated Arina Rodionova, a player ranked more than 200 places above her, in the first round. She did it in straight sets to make it three consecutive wins since touching down in Sao Paulo.
The 28-year-old, who is having a topsy-turvy year, has thus improved to 20-17. Okalova is competing in the main draw of a tour tournament for the first time.
Advancing to this round has catapulted the Serbian a massive 90 places in the live ranking to 374th.

Our Janice Tjen vs Martina Okalova Prediction
Okalova and Tjen were in strong form in the first round, winning both of their openers in straight sets. The qualifier Okalova has gained some momentum now with three successive wins in Sao Paulo. It is, however, not her that we have as our bet to win this tie.
This is because Tjen is in far better form and is having a dominant year. With 60 victories, Tjen has won 84% of her total duels this year and has registered over 50 wins on hard courts. It is also worth noting that Okalova has never won more than one main draw tie at a tour event. Our prediction for Janice Tjen v Martina Okalova is for Tjen to win in straight sets.
