Caroline Wozniacki defended Emma Raducanu against John Isner’s remarks questioning the significance of Raducanu’s historic US Open victory. Raducanu, the British sensation, made headlines in 2021 by becoming the first-ever qualifier to win a Grand Slam title at Flushing Meadows.

The 23-year-old, then a teenager, impressively won 10 consecutive matches without dropping a set to claim the championship after a thrilling final against Leylah Fernandez. This achievement was widely acclaimed as one of the most remarkable feats in tennis.

In another surprising turn of events, Valentin Vacherot recently became the lowest-ranked player to win a Masters title in Shanghai. Vacherot’s path to victory included notable wins over Alexander Bublik, Holger Rune, Novak Djokovic, and his cousin Arthur Rinderknech in the final.

Isner, a retired American player who once reached the world No. 8 ranking, controversially stated on the Nothing Major Show that Vacherot’s accomplishment was more impressive than Raducanu’s US Open win. However, Wozniacki disagreed, emphasizing that winning a Grand Slam title holds greater significance in tennis.

Wozniacki, the 2018 Australian Open champion, recently made a comeback to professional tennis after briefly retiring in 2022. Despite giving birth to her third child, her return to the sport included appearances at prestigious events like the US Open, Indian Wells Open, and the Paris Olympics.

Raducanu, on the other hand, has faced challenges in replicating her US Open success. Reflecting on the comparisons made to her historic victory, she acknowledged the lingering impact it has had on her mindset. Despite trying therapy, Raducanu found it difficult to relate her experiences to others and opted to rely on her own resilience.
