Świątek, who plays brilliantly on clay courts when open to the air, may not be rewarded by the closed roof. Experts say that the move to indoor-like conditions will mean reduced efficacy of her topspin-heavy game.

Sabalenka's Power Game Could Benefit From Closed Roof
A number of tennis analysts also think the indoor conditions could give Aryna Sabalenka the edge. The slower court surface that a closed roof will induce should temper the spin and variety that Świątek relies on to steamroll her opponents. Sabalenka, who is more about strength and power, could be comfortable in these conditions that are more favorable to playing on the front foot.

A few observers have also noted that Świątek loves outdoor conditions, including the breezes and light changes, that indoor conditions would eliminate. Given the unpredictable weather, both players could confront a subtle mental and tactical test in this semifinal.
