Stoiana vs Badosa Prediction 18 September 2026
🔊 Mary Stoiana reached her first WTA main-tour quarter-final at the WTA 250 in São Paulo. There she faces experienced former world No. 2 Paula Badosa. Notably, the Spaniard's path to the last eight was considerably more difficult: her original first-round opponent withdrew, tropical Brazilian rain caused further disruption, and in the second round she had to come from a set down. Stoiana, meanwhile, won both her matches without dropping a set. It will be interesting to see whether she can push Badosa and set a new career-best result at WTA level.

Match Results: Mary Stoiana
Paula Badosa Player Overview
Paula Badosa is also in decent form, with the same seven wins from her last ten matches. Last summer she missed part of the hard-court swing due to a planned medical procedure, so her only tournament before São Paulo was the US Open, where she lost in the second round. In Brazil, she has beaten Justina Mikulskyte 6-3, 6-2 and Jazmin Ortenzi 4-6, 6-2, 6-2 in successive rounds. Compared to Stoiana, Badosa has slightly stronger overall numbers, winning 57% of all games and leading in sets won at 71%. She is a classic aggressive baseliner with a notably powerful serve that she hits at close to 200 km/h, holding at 62%.
Match Results: Paula Badosa
Key factors
- Mary Stoiana won more than 11.5 games in 7 of her last 8 matches.
- The average number of games in matches involving Mary Stoiana is 23.3.
- She has won 55% of all games and 63% of sets over her last 10 matches.
- Paula Badosa's run to the quarter-final has been more demanding in terms of effort and time on court.
Expected scenario
Badosa is expected to take control from the early games, using a powerful first serve and deep, heavy groundstrokes from the baseline to keep the less experienced American on the defensive at a high tempo. However, Stoiana, who is adept at disrupting rhythm with a signature slice backhand and moving forward to the net, will look to take Badosa out of her comfort zone and force unforced errors.
Total Games Prediction
Mary Stoiana has regularly gone over her individual total line recently. She tends to stay competitive even against higher-ranked opponents, as seen in the first round against Claire Liu, whom she beat as an underdog.
⭐ Editor's Pick
The central storyline is the clash between Paula Badosa's attacking directness and Mary Stoiana's tactical variety. Much will depend on whether the American can stay composed on the key break points against a former world No. 2, or whether Paula Badosa's superior class, physical power and ability to grind out difficult comebacks on hard courts ultimately wears down a bold quarter-final debutante at WTA level. That said, it seems Mary has everything in place for a strong performance, particularly given the difficult route the Spaniard has had to São Paulo. We're backing the underdog: Stoiana - Games Handicap +4.5.
