Diana Shnaider produced the upset of the tournament. The 25th seed stunned world No.1 Aryna Sabalenka in the Roland-Garros quarter-finals, 3-6, 7-5, 6-0, in two hours and twelve minutes on Court Philippe-Chatrier.
Sabalenka appeared to be in complete control. After pocketing the first set, she led 4-1 in the second and even served for the match at 5-4. The script seemed written. Then everything collapsed.
A forehand into the net, a double fault, a string of uncharacteristic errors. Shnaider sensed the opening and seized it with fierce determination. The 22-year-old Russian won ten consecutive games to turn the match on its head, delivering a devastating 6-0 bagel in the decider.
The numbers tell the story of the collapse. Sabalenka committed 57 unforced errors across the match, including 17 in the third set alone. Shnaider struck 25 winners, 10 of them in the final set. Gusty winds swirling around Chatrier clearly unsettled the four-time Grand Slam champion, who could not recover her rhythm after losing the second set.
"I was just trying to focus point by point, not thinking about the score," Shnaider explained after the match. "It was my first time playing Aryna, I was super nervous."
Sabalenka offered no excuses. "I had very decent opportunities in the second set. I screwed it up, and then she stepped in and played great. I couldn't really recover after the second set."
The quarter-final marks Shnaider's first appearance in a Grand Slam semi-final. She will face Polish qualifier Maja Chwalińska for a spot in the final. In a historic footnote, all four women's semi-finalists were born in the 21st century, a first at any Grand Slam.
