World No. 1 Aryna Sabalenka suffered a shocking defeat at Roland-Garros, losing to 25th seed Diana Shnaider 6-3, 5-7, 0-6 after squandering a significant lead in the second set. Sabalenka, who had not dropped a set prior to this match, revealed that she felt so demoralized she wanted to "quit tennis right now," attributing her collapse to a mental inability to recover after the second set, which she described as her "biggest mistake." The match, played under windy conditions on Court Philippe-Chatrier, saw Sabalenka leading 4-1 in the second set before losing 12 of the last 13 games, ultimately making 57 unforced errors. Shnaider, a first-time Grand Slam quarter-finalist, capitalized on Sabalenka's errors and increasing frustration to secure her spot in the semi-finals.
