WTA Porto Preview, 21 September 2026: Dodin’s Power Meets Bandecchi’s Control

Porto’s first round on 21 September brings four distinct tests on hard courts. Océane Dodin must control her power, Sinja Kraus needs an immediate response, and Anouk Koevermans is trying to turn a Grand Slam breakthrough into weekly consistency.

The day also gives home wildcard Carla Tomai another chance after a severe defeat in Caldas. These are the four matches I find most revealing:

11:30 — Anouk Koevermans — Ayana Akli
13:00 — Lizette Cabrera — Sinja Kraus
13:00 — Kajsa Rinaldo Persson — Carla Tomai
15:00 — Susan Bandecchi — Océane Dodin

Times are UTC.

Anouk Koevermans — Ayana Akli

Koevermans has the stronger recent reference point after qualifying for her first US Open main draw. Her message in New York was simple: “To show that I belong here” (Eurosport).

Her Caldas results showed both sides of the next step. Koevermans recovered after losing a long second set to beat Elena Micic 6-2, 6-7, 6-3, but Gabriela Knutson then kept her behind the baseline in a 6-3, 6-2 defeat.

Akli arrives on three consecutive losses, including a 6-3, 6-0 defeat to Noma Noha Akugue. Yet her 13-5 hard-court record this season warns against treating that run as her full level; she can take the return early and make Koevermans rush.

They have not met before. The key is whether Koevermans can move Akli laterally and protect her second serve when the first set tightens, rather than entering a straight-line hitting contest.

I lean toward Koevermans because her point construction and composure are currently more reliable, but this is not a clean mismatch. Akli has enough hard-court quality to make over 20.5 games reachable if she starts assertively.

Lizette Cabrera — Sinja Kraus

Kraus owns the heavier rally ball and the much stronger ranking, but her last appearance cannot be brushed aside. Mia Pohankova beat her 1-6, 1-6 in Caldas, with Kraus failing to establish depth or resistance after the opening games.

That performance followed losses to Karolina Muchova, En Shuo Liang and Sloane Stephens. Kraus has previously shown greater resilience, and her earlier reaction to reaching the top 100 — “This little girl would be so proud” (Wiener Tennisverband) — reflects the larger progress behind one poor week.

Cabrera has also lost four straight, although the sequence began after an excellent 7-5, 6-7, 6-4 win over Talia Gibson. Her recent problem has been maintaining authority after competitive openings, especially once service games become longer and the second serve comes under pressure.

There is no previous meeting. Kraus should attack Cabrera’s second serve and control the backhand exchange, while Cabrera’s route is to keep the ball in play until the Austrian is asked to hit another finishing shot under pressure.

I still think Kraus is closer to the win, but the margin looks less secure than the ranking gap suggests. Cabrera at +5.5 games looks capable of staying relevant if Kraus carries any tension from Caldas into the opening set.

Kajsa Rinaldo Persson — Carla Tomai

Rinaldo Persson has already shown that she can solve difficult passages on Portuguese hard courts. She closed strongly to beat Angelina Voloshchuk 6-3, 7-5, then pushed eventual Caldas champion Lisa Pigato into a decider.

Tomai has won only four games across her last five hard-court defeats. Jeline Vandromme beat her 6-0, 6-0 last week, controlling the court before Tomai could establish a neutral rally.

The Portuguese wildcard says that training means “persisting and always making an effort” (Federação Portuguesa de Ténis). That attitude matters, although the scoreboard does not issue certificates for persistence.

Rinaldo Persson does not need ambitious changes of direction here. Deep cross-court patterns, disciplined returns and routine first-service holds should steadily expose Tomai’s difficulty absorbing pace.

I expect Rinaldo Persson to win in straight sets, probably without an extended pressure game at the finish. Tomai’s first task is simply to hold serve early enough to prevent another match from accelerating beyond control.

Susan Bandecchi — Océane Dodin

This is the day’s most compelling tactical contest. Bandecchi brings the steadier rally structure, while Dodin owns the serve and first strike capable of taking the racquet out of an opponent’s hands.

Bandecchi is 16-7 on hard courts this season and reached the Caldas quarterfinal after two straight-set wins. Against Lisa Pigato she recovered from losing the opener, dominated the second set 6-1 and then fell 6-4 in the decider after the closing games tightened.

Dodin has lost three in a row, all after competitive phases. She forced Reese Brantmeier into a decider but surrendered the decisive break late, while earlier defeats to Sofia Johnson and Caroline Werner slipped away after Dodin had won the opening set.

No fresh injury has been reported for either player. Dodin’s history of inner-ear trouble and vertigo remains relevant background, but she has returned to a regular schedule and completed several long matches.

Bandecchi won their only previous meeting 6-2, 6-1 in the Lausanne first round on 11 July 2022. That result came on clay and carries limited tactical weight here, although it confirms that Bandecchi has previously handled Dodin’s direct pace.

It is the sort of basket drill in which Bandecchi keeps sending one more deep ball until Dodin proves she can finish without rushing. Dodin must shorten points without treating every neutral ball as an order to fire.

I expect Bandecchi’s discipline to prevail more often across the pressure games, with straight sets slightly likelier than a decider. Her -4 games line looks justified if she keeps returns deep and makes Dodin work through a second and third shot.

Control tests power in Porto

The central question is whether the favourites can impose routine rather than merely superior shot quality. I would give most attention to Kraus’s first difficult service game and to Dodin’s patience once Bandecchi begins extending rallies.

Koevermans against Akli has the best chance of becoming a genuine first-round argument, while Rinaldo Persson’s assignment is about professional efficiency. The AI cappers provide the concrete selections on the individual match pages; the tennis questions here begin with discipline under pressure.
