São Paulo quarterfinals, 18 September 2026: Badosa's body, Podoroska's comeback and two kids with nothing to lose

The quarterfinals in São Paulo have arrived without the names anyone drew up in advance. Paula Badosa is still the marquee, and she is still, by her own account, negotiating with her own body rather than trusting it blindly. Behind her, Nadia Podoroska and Suzan Lamens have quietly knocked out the pairing this half of the draw was supposed to produce, and the first match of the day belongs to two players in their late teens and early twenties who have taken to these outdoor hard courts faster than the rankings suggested they would.

The thread running through all four is recovery. Everyone here played on Thursday, and the question is not who can reach a high level but who can reproduce Thursday's level on Friday without paying for it in the third set. I'll go through these:

16:00 — Teodora Kostovic — Kaitlin Quevedo
17:30 — Anna Blinkova — Alina Charaeva
20:30 — Mary Stoiana — Paula Badosa
22:00 — Nadia Podoroska — Suzan Lamens

Times are UTC.

Teodora Kostovic — Kaitlin Quevedo

Kostovic is nineteen, hits the ball as if apologies were a sign of weakness, and has spent most of her young career on clay — four hard-court matches in all of last season, nine this year, and only three of those won before this week. So the way she has handled São Paulo is genuinely surprising. Victoria Barros made her work late in the first round, and Darja Semenistaja, ranked sixty places above her, kept the opening set tight before losing it and then everything else, 6-4 6-1. Once Kostovic is ahead, the power starts landing rather than flying.

Quevedo, a year older and around eighty places higher, has had the smoother week: a 6-0 6-2 dismissal of Anastasia Tikhonova, then a 6-2 6-1 win over Nauhany Silva in which the local crowd's hope drained away in about forty minutes. Her strength is that bad beginnings do not frighten her — the Silva match started with a break against her and Quevedo simply became more efficient rather than more desperate. "I'll try to go in like any other match, let loose and play, because when I let loose I play really well," she has said (Clay Tenis). They met in May in Roland Garros qualifying, and Quevedo won it the hard way, 7-6(3) 3-6 6-2 on clay.

Kostovic has had an extra day of rest, which on a compressed schedule is not nothing, and her belief has never been in question — this is the player who announced at Wimbledon that she could beat anybody in the zone. But zones are a poor foundation for a quarterfinal, and Quevedo's habit of returning one extra ball is precisely the thing that turns aggression into impatience.

I lean to Quevedo at around 1.68, mostly because she has the steadier competitive structure and the better hard-court record over two seasons. But Kostovic's serve and first strike can make sets disappear, and she is priced generously at +2 games; I expect a match nearer three sets than two, with the 21.5 total more likely to go over than under.

Anna Blinkova — Alina Charaeva

Blinkova has been the tidiest player in the draw this week. Carol Young Suh Lee got 6-1 6-3, Vendula Valdmannova competed for about a set before losing 6-3 6-0, and neither match cost her anything emotionally. That matters, because her broader year on hard courts has been middling at best, and she came to Brazil straight from a deep run in Barranquilla. This is also her first tournament representing France after a long naturalisation process — a new flag, an old game.

Charaeva's route has been more instructive. She was in trouble against Xiaodi You, losing the first set and surviving a tie-break before winning 3-6 7-6(5) 6-3, and then played with real clarity against Elina Avanesyan, 6-2 6-3 with no drama at all. She has talked about why her level has stabilised: "I've had far fewer injuries… I started playing more matches in succession and became more confident," she told Championat. Continuity, not talent, was the missing piece.

They have never played. Blinkova owns the first-strike template — take the ball early, redirect, deny the opponent time — and when it works she makes matches feel over before they start. Her weakness is streakiness: when the timing slips, she has to build points from neutral, and that is where her legs, not her hands, become the issue. Charaeva's sensible plan is to extend rallies and wait for the short ball rather than trying to out-hit her from the first shot.

Blinkova at 1.55 looks about right as the favourite, but −3 games asks her to be as clean as she was on Thursday against someone who will not hand over the middle of the court. I expect a longer, more physical afternoon than her first two rounds and would rather be on the over of 21 than the handicap.

Mary Stoiana — Paula Badosa

This is the match the tournament was built around, and it is also the one with the largest asterisk. Badosa's back is a managed condition rather than a fresh alarm, she has dealt with hip and shoulder trouble, and she is entirely open about the hierarchy now: "Physically, I've had a few good months now… Today my physical condition is the priority," she has said (ITF). After turning around Jazmin Ortenzi 4-6 6-2 6-2 she sounded relieved more than triumphant: "I'm happy that my body is responding well; that is what matters most at this point in my career" (SP Open).

The tennis in that Ortenzi match was the real story. Badosa let an unfamiliar opponent settle into a running, countering pattern, then changed the shape of the rallies and took over — "I tried to change the game plan a little, and it worked well in the second and third sets," as she put it. Her opener against Justina Mikulskyte, 6-3 6-2, was economical and heavy. So the problem-solving is intact; the slow diagnosis against players she does not know is the warning, and Stoiana is exactly that kind of player.

Stoiana, 23 and a recent product of American college tennis, has not been lucky here. She beat Claire Liu 6-3 7-5 through several shifts of initiative, then held her nerve in a tense first set against Dominika Salkova before the 7-6(5) 6-1 became a runaway. Hard courts are where she has always made sense — her best season by far came on them — and she describes herself as an all-court player who likes the slice backhand, changes of pace and finishing at the net. Against a power baseliner still rebuilding trust in her movement, that variety is the right idea rather than a pretty one: pull Badosa forward, break up her strike zone, refuse the straight power exchange. They have never met, and the freedom belongs entirely to the American.

Badosa at 1.45 is fair on quality — her serve and first groundstroke are simply better weapons on this surface. But I am not convinced by −3.5 games the day after a three-set reset with that medical history, and Stoiana at +3.5 looks like the sturdier side of the same opinion. My expectation: Badosa through, probably in a decider, with the 21 total beaten.

Nadia Podoroska — Suzan Lamens

Two players who were not supposed to be here, playing for the semifinal nobody assigned them. Podoroska is ranked outside the top 300 because injuries took years from her — hip, shoulder, then forearm tendon inflammation — and her reassurance this season has been mechanical rather than sentimental: "My body responded very well, and that gives me the peace of mind and confidence that I have recovered," she said after winning her first title of the comeback (Infobae). Her hard-court year has quietly become excellent, and the 7-5 6-2 win over Eva Lys, ranked more than two hundred places above her, was the proof. The set was not clean — she kept failing to close it — and the point is that she stayed calm through it: "I was able to get through the situation, become calmer and win the game" (SP Open). Playing this close to Argentina, she added, "is a different feeling, and it makes me want to go further."

Lamens' week has run the other way round. She was scrappy and nearly gone against Carolina Meligeni Alves, losing the first set and escaping 3-6 7-6(2) 6-2, then produced her cleanest hard-court tennis of the season to beat Solana Sierra 6-3 6-2 — flatter, earlier, far less prone to drifting with the momentum. That is a dramatic correction for a player whose hard-court season had been close to a write-off. They did meet once, in the first round of a small event in Den Haag in July 2019, when Lamens won 6-0 6-3 on clay; seven years and two very different careers later, it tells us nothing.

Stylistically this is the most honest contest of the day, and it turns on the vertical shape of the rally. If Lamens can hit flat and early, she rushes Podoroska before the Argentine builds her heavier pattern. If Podoroska varies height and spin and makes Lamens strike from awkward contact points, it becomes a movement and patience examination, and she wins those. Both had short Thursdays, though Lamens carries the extra three-setter in her legs.

Podoroska at 1.72 is the side I trust more — the physical steadiness of her last two matches is worth more to me than Lamens' one excellent night. Still, −2 games feels thin against a player striking it as cleanly as Lamens did against Sierra, and I would expect something long and fought, likely over the 21.5 games.

Four quarterfinals, one shared question: whose legs survive Thursday

The day has a single spine. Badosa's problem-solving against Ortenzi was the best thing she has done this week and possibly the most expensive; Blinkova's São Paulo tennis looks fresh while her calendar does not; Lamens carries an extra set in her body; Kostovic is the one player who genuinely rested. Everything else — Podoroska's comeback reaching a tour semifinal, Stoiana's variety against an established power game, Charaeva's new-found continuity — sits on top of that.

If I had to pick one match to sit down for, it is Podoroska and Lamens at 22:00, because the two people who wrecked the draw deserve to decide it between themselves. The specific numbers on all four are the AI cappers' business, and they get properly detailed about them on the match pages.
