Caldas da Rainha semifinals, 19 September: Pohankova's calm against Knutson's mileage, and Vandromme's tired legs

Semifinal Saturday in Caldas da Rainha, and the draw has arranged itself into two neat little essays. First a prodigy against a late bloomer: Mia Pohankova, seventeen and still surprised by nothing, against Gabriela Knutson, twenty-nine, a finalist on these courts a year ago and a woman who came to professional tennis the long way round. Then the more combustible one: Lisa Pigato, rebuilt and serene, against Jeline Vandromme, who plays as if the second ball is already too late.

The variable that hangs over the whole day is recovery. Three of the four needed proper quarterfinals on Friday, and Vandromme needed more than three hours of one, which is a strange thing to carry into a semifinal at eighteen. I'll take them in order of play:

10:00 — Pohankova — Knutson
11:30 — Pigato — Vandromme

Times are UTC.

Pohankova — Knutson

Pohankova has spent the week making this look easier than it is. She opened by taking Sinja Kraus, ranked 95th and the biggest name in her quarter, apart 6-1 6-1, then handled the home player Matilde Jorge 6-4 6-1. Friday was the first day the scoreboard argued with her: Kylie Collins climbed back, reached the point of serving out the opening set, and Pohankova simply refused the ending, dragged it into a tie-break and played that tie-break with a clarity Collins couldn't match. 7-6(3) 6-4, and three matches here without losing a set.

Knutson's route was heavier. She survived Aoi Ito 7-6(4) 6-2, dismissed Anouk Koevermans, then spent nearly two and a half hours beating Malaika Rapolu 6-2 1-6 6-4, a match in which her timing vanished for a full set and came back late. She knows the place — a final here last year, and seven wins against one defeat at this tournament tell you the courts suit her flat, forward-leaning tennis. She is also fresh off a first Grand Slam main draw, about which she was disarmingly honest: "I played the main draw for the first time. It definitely showed in my nerves", though she added that she is playing better and better and that continuing this journey makes sense (iROZHLAS).

They have never met, which makes the stylistic question pure. Knutson wants short points and the first strike; Pohankova wants the rally to last one ball longer than her opponent intended. Her old coach Mojmir Mihal described her tennis as light and relaxed, "a boyish style, with good movement and excellent thinking" (Sportnet), and that thinking is exactly what punishes a player whose legs are two hours short. Pohankova has also said, with unusual realism for a junior champion, that people assume success makes everything easy while opponents only grow hungrier (Sportnet). Nobody has looked hungrier than her this week.

The market has Pohankova at 1.68 and I think that is roughly right, maybe a touch generous. She has the fresher legs, the cleaner week and, so far, the better answers when a set starts slipping. But Knutson's experience of ugly matches is real, and her middle-set collapse against Rapolu was followed by a decider she won on stubbornness, so I'd expect games rather than a rout: the 21.5 total looks likelier to go over than under, and the −2 handicap on Pohankova feels tighter than it reads.

Pigato — Vandromme

This is the match of the day, and it is decided as much by Friday as by Saturday. Vandromme beat Francisca Jorge 6-3 6-7(7) 7-5 in over three hours, having built what looked a decisive lead in the decider before the home crowd and her own tightening arm wiped it out. She stopped the slide with two games to spare, which is admirable, but a semifinal against a hard-hitting Italian is a brutal reward for that kind of afternoon.

Pigato's quarterfinal had the same shape and half the cost: 6-4 1-6 6-4 over Susan Bandecchi, a middle set she lost comprehensively and then declined to think about. That is the theme of her season. "The results are a consequence of the work we have done. I have rediscovered much more joy and serenity, together with consistent work from my team", she said earlier this year (SuperTennis), and after groin surgery in late 2024 she has reported no serious physical trouble since coming back. Three wins, three matches here, all of them on hard, where she is 10-3 this year.

Vandromme, for her part, is the more natural hard-court animal: 22-2 on the surface last season, 9-2 this one, and entirely unapologetic about it — "I am definitely an aggressive player. I like to dominate the game… I try to dictate play", she told Tennis Actu (Tennis Actu). The complication is her summer: withdrawals including Cincinnati, with the Warsaw pull-out attributed to her right elbow, and her own line at the time that her full attention was going to recovery (Tennisplaza). No sign of trouble in three matches here, but three hours of grinding is a fair test of a healed arm.

They have met once, in a W15 semifinal at Gonesse in March 2025, and Pigato came back from a set down to win 5-7 6-2 6-0 — a clay match, small stage, and the score of a player who works out a problem mid-match. That is the pattern to hold in mind: Vandromme starts fast, Pigato survives the first storm and asks questions later.

Vandromme at 1.28 looks short to me — that price ignores three hours in her legs and an elbow that was a genuine concern six weeks ago. I lean towards a long, untidy match rather than a Belgian procession: Pigato at +5 on games is the part of this line I find most sensible, and the 20-game total feels low for two players who keep needing deciders. Vandromme is still the better hard-court striker and may well win it; I just doubt she does it quickly.

A teenager who hasn't dropped a set, and a Belgian running on empty

The day comes down to two questions. Whether Pohankova's composure — genuinely the most impressive thing in Caldas this week — holds against someone who has played twelve career finals and lost half of them without losing her nerve; and whether Vandromme has anything left after Friday, because Pigato will happily make her hit forty more balls than she wants to.

My hunch is that both semifinals go the distance and that fatigue, not talent, writes the scorelines. The specific numbers are the AI cappers' business — they get down to the detail on the match pages, and they are usually less sentimental about tired teenagers than I am.
