Once the women’s singles quarterfinals at the China Open were set, the subsequent two major upsets made Swiatek and Andreyeva, who both lost, the unfortunate protagonists.

Swiatek versus Navarro and Andreyeva against Qatar were the two spotlight matches, and before they began, the Polish girl and the Russian talent were the unquestioned favorites in the eyes of betting companies, confidently expected to win. However, nobody anticipated that the surprises would arrive sooner than expected.
Swiatek and Navarro met in the China Open round of 16 in a dramatic encounter, with both their previous opponents retiring due to injury, allowing the two players to advance easily and face each other.
Given Swiatek’s undeniable strength, many believed the wealthy American had little chance to overcome the top seed, suggesting that taking even one set off Swiatek would be an extraordinary feat, and getting swept in straight sets was considered normal.

However, once the match began, it was Swiatek, not Navarro, who first ran into trouble.
After the American heiress took the first set 6-4, this unexpected outcome caused Swiatek’s confidence to sharply decline. The public’s doubt was not about her skill but rather speculation that she might be injured, as many clearly advantageous shots were missed—this was the main reason for her losing the opening set.
Fortunately, starting from the second set, Swiatek improved her stability, quickly reversing the unfavorable situation on court by returning a 6-4 set win to Navarro, leveling the match.
Seeing the Polish player’s form improve significantly, supporters in the live broadcast room breathed a sigh of relief, proclaiming that a major comeback by the top seed was imminent.

Surprisingly, in the decisive final set, Swiatek showed no signs of a comeback; instead, she appeared to collapse and ultimately lost the match without winning a single game, causing a stir in the tennis community.
The strong reaction from the public stemmed from the fact that Swiatek rarely loses a set 6-0. Even top players like Sabalenka and Gauff find it nearly impossible to deliver a bagel against the Polish star, yet Navarro managed to do just that.
Nevertheless, the American heiress’s performance against Swiatek was truly remarkable. Many praised her for delivering her best form in this match. Her consistency surpassed that of the top seed, and although she seemed at a disadvantage in rallies, she consistently returned balls deep and kept them in play, laying a solid foundation for her eventual victory.

After the match, some joked that the American heiress had taken out Swiatek, and if she ended up paving the way for Pegula, becoming the biggest helper, "one wonders if the second-richest player would cry in the bathroom?"
Before Pegula was confirmed as Navarro’s quarterfinal opponent, the American’s coach stayed behind after the match to gather information. This clearly showed concern that his player might inadvertently clear the path for someone else, so he wanted to prepare thoroughly for upcoming matches to help his player progress smoothly.
Whether Navarro would become Pegula’s stepping stone would only be known after their match concluded. Meanwhile, Swiatek’s bagel loss was the biggest upset of the day at the China Open, quickly making her the focus of everyone’s concern, eager to understand what really happened to her.

“I’m not injured; I just didn’t perform well today,” Swiatek’s statement immediately reassured those who worried her poor play was due to injury. After all, form can be adjusted, but an injury at this crucial time, with the race for world No.1 against Sabalenka heating up, would have been very unfortunate.
Regarding why she lost the final set 6-0, Swiatek’s explanation confused many: “I managed to correct some issues in the second set that caused problems in the first, but in the third set, the same problems reoccurred. I don’t know, I didn’t really solve them. Maybe I knew what I did wrong but couldn’t fix it, which made me more nervous. That nervousness then led to emotional swings. Next time, I’ll try to handle these problems more calmly and rationally. Today, I felt nothing was working on court, so I got increasingly anxious.”

Many found it hard to understand Swiatek’s claim that her bagel loss was due to being unable to solve problems on court, which triggered nervous breakdown and collapse.
Considering her extensive experience in big matches and numerous comebacks from difficult situations, the Polish player’s nervous collapse at such a critical moment is baffling and remains a mystery in the tennis world.

If Swiatek’s upset loss to Navarro was somewhat understandable, then Andreyeva’s elimination by Qatar was truly astonishing. In terms of skill, reputation, and record, Andreyeva was superior, yet she suffered a shock defeat, missing a golden chance to cause the top seed’s exit, which deeply saddened the Russian prodigy’s fans.(Source: Tennis Home, Author: Moon River’s Starry Sky)
