The elimination of the World No. 1 in the quarterfinals disrupts the projected path to the French Open title. Sabalenka's collapse in the third set, winning zero games, suggests a significant breakdown in composure or physical endurance, while Shnaider's ability to recover from a substantial deficit establishes her as a dangerous contender for the remainder of the tournament.
