Pegula’s route past Sabalenka starts with the return she can repeat

Aryna Sabalenka and Jessica Pegula will meet in the US Open semi-finals after both recovered to win demanding quarter-finals on 8 September. SuperSport’s results service records Pegula’s 3–6, 6–4, 6–3 victory over Emma Navarro; Sabalenka edged Linda Noskova 7–6(1), 3–6, 7–6(7). Their semi-final pairing is also confirmed in AS’s updated report.

Our central question is not which player looks more forceful in a highlight. It is whether Pegula can repeatedly take away Sabalenka’s comfortable first groundstroke. Winning that small positional argument would give the American a way into the match that does not require an exceptional return on every important point.

Borrow the pressure, not the entire Noskova performance

The WTA’s quarter-final account describes Noskova returning deep at Sabalenka’s feet and taking a 4–2 lead in the deciding set. It also records Sabalenka finishing with a second-serve ace. That combination is instructive: the same service game can offer the returner an opportunity and still contain a delivery she cannot control.

Pegula should therefore build a plan around the returns she can reproduce. A deep central target is our preferred starting point against a strong serve. It reduces the available angle for the next shot and offers a larger margin than a return driven close to a sideline. The objective is to earn a balanced second exchange, not to declare an attacking intention immediately.

That is not an argument for passivity. A genuinely attackable serve deserves a more aggressive answer. The distinction is between stepping in because the ball permits it and deciding before contact that a return winner is needed. If Pegula gets the first decision right, she can reserve the change of direction for a ball on which her feet are set.

Sabalenka needs a serve-and-next-ball partnership

For Sabalenka, chasing an ace on every pressure point would be an unnecessarily fragile solution. Our preference is a serve location paired with a clear next action: a body serve that restricts the swing, for example, followed by an attack on the reply if it is short enough. A wide serve has a different cost because it opens the court to a return angle as well as pulling the receiver out.

Recovering towards the likely reply is part of the service action. If Sabalenka is balanced when the return arrives, her power becomes a choice about where to attack. If she is still moving into position, the same ambitious swing asks for much finer timing. Pegula should be trying to create that difference, not simply to survive the pace.

The score should change the risk, not the identity

Our Navarro–Pegula preview considered how variation might interrupt a comfortable baseline rhythm. Against Sabalenka, Pegula’s variation should also have a destination. A higher, deeper ball can buy time to recover; a sudden short ball is a poor bargain if it merely gives an opponent an easy run forwards.

There is a real counterargument to our central-return preference: too much repetition can let Sabalenka prepare early and dictate the next shot. Pegula will need occasional changes of return position and direction. We would introduce those after establishing the reliable option, so that the variation complicates the server’s decision without making the returner’s task unmanageable.

Nor should either player assume a three-set quarter-final proves a physical disadvantage in the next round. Recovery differs between players, and we have no verified medical or conditioning assessment. Footwork and decision-making during the semi-final will be more useful evidence than assigning fatigue from the previous score.

Our semi-final call

We lean towards Sabalenka, with three sets a plausible route rather than a promised outcome. Pegula becomes the stronger proposition if she keeps reaching the first neutral ball in balance and makes Sabalenka attack from less comfortable positions. The favourite’s case strengthens if the serve repeatedly supplies a short reply that can be attacked without stretching.

This is a tactical judgement, not a measured win probability. The return need not be spectacular to change this match. It needs to leave the next shot difficult often enough.
