1. Sankar Subramanian Stuns Anders Antonsen
One of the biggest upsets of the tournament came in the men’s singles when India’s Sankar Subramanian Muthusamy, ranked 64th in the world, stunned World No. 2 Anders Antonsen in the pre-quarterfinals. After losing the first game 18-21, Sankar staged a brilliant comeback, winning the next two games 21-12, 21-5 to secure his spot in the quarterfinals. The result sent shockwaves through the tournament, marking a career-defining moment for the young Indian shuttler.
Sankar has been a rising star in Indian badminton, having previously won silver at the 2022 World Junior Championships. His steady improvement on the senior circuit and ability to take down top-ranked opponents suggest a bright future ahead.
2. PV Sindhu’s Early Exit
Two-time Olympic medalist PV Sindhu faced a shocking first-round exit at the hands of unseeded Julie Jakobsen. Sindhu, who was expected to make a deep run, struggled with her form and was unable to fend off the challenge from the Danish shuttler, losing 21-17, 21-19. Sindhu, visibly frustrated after losing the final point, momentarily tossed her racket into the air. However, she swiftly caught it before it could hit the court and then proceeded with the post-match formalities, shaking hands with the chair umpire and her opponent, Julie.
Sindhu has been going through a rough patch in recent times, with inconsistent performances in major tournaments. Injuries and coaching changes have played a role in her struggles, and this latest setback highlights the challenges she has faced in regaining her top form.
3. Christo Popov’s Dream Run
French shuttler Christo Popov, ranked 31st in the world, emerged as one of the standout performers of the tournament. Popov pulled off two major upsets, defeating World No. 5 Chou Tien-chen and the former All-England champion Li Shifeng. His aggressive gameplay and fearless approach saw him progress to the finals, making him one of the biggest surprises of the tournament.
Popov has been steadily making a name for himself in European badminton. He previously won silver at the 2020 European Junior Championships and has been a key part of France’s rising badminton scene. His performances at the Swiss Open indicate that he is ready to challenge the sport’s elite players on a consistent basis.
4. Lin Chun-Yi Continues His Giant-Killing Streak
Chinese Taipei’s Lin Chun-Yi added another big name to his list of victims by defeating reigning World Champion Kunlavut Vitidsarn in the quarterfinals. Lin, who has been in exceptional form, showcased his incredible skills to advance to the semis.
This win was particularly significant as the left-hander had recently defeated Viktor Axelsen at the All-England Open as well, proving that his success was no fluke. His ability to take down multiple top-ranked players in quick succession marks him as a rising force in men’s singles badminton.
While upsets are an integral part of any major badminton tournament, the Swiss Open 2025 saw an unusually high number of top players faltering against lower-ranked opponents. This unpredictability made it one of the most exciting editions in recent years, reinforcing the idea that in badminton, rankings and reputation offer no guarantees. Whether it was due to emerging talent, fatigue among top players, or simply the unpredictable nature of the sport, this tournament will be remembered as one where the underdogs truly had their day.
