"I took lessons from Aryna's struggles in last year's wind‑hit French Open final," Shnaider said [1].

The match took place June 3 [1], [4] at Roland Garros in Paris. The conditions on the court mirrored the volatile weather that had plagued Sabalenka in previous encounters, leading to a series of unforced errors from the favorite [3].

Sabalenka expressed deep frustration following the loss. "I just want to quit tennis right now," Sabalenka said [5].

Shnaider's strategic approach allowed her to maintain composure while the world No. 1 struggled to adjust to the gusts [1], [3]. This upset continues a trend of unexpected results rocking the French Open this year [2].
