Wozniacki challenges Isner’s comparison as debate over Raducanu’s breakthrough reignites
Caroline Wozniacki took center stage during her appearance on John Isner’s “Nothing Major Show” podcast recently. She challenged Isner over his October claim that Valentin Vacherot’s Shanghai Masters triumph was more impressive than Emma Raducanu’s 2021 US Open title run. The conversation, sparked by Vacherot’s “improbable” rise from qualifying to winning a Masters 1000, turned into a spirited exchange about context, achievement, and what defines greatness across both tours. Let’s dig deeper into the conversation.
The discussion gained traction after Isner doubled down on comments he made in October, when he argued that Vacherot’s Shanghai title was “more improbable” than Raducanu’s unbeaten 10-match run from qualifiers to a Grand Slam championship in New York. On the podcast, Isner revisited the topic and said, “I think it is more impressive, yes. (For Raducanu) it’s a bigger story because it’s the US Open, but I think this is more improbable than what she did.”
Wozniacki pushed back immediately. When Isner reiterated his stance, she responded with a firm “No,” before laying out her reasoning. She highlighted that Raducanu entered the 2021 US Open as an unknown teenager, came through qualifying, and did not drop a single set on her way to the title. “No matter how you slice and dice it. That’s better than winning a 1000,” Wozniacki argued. She acknowledged the difficulty of Vacherot’s path but maintained that the magnitude of a Grand Slam triumph outweighs a Masters victory.
Isner countered by emphasizing the statistical improbability of Vacherot’s run, noting he had only one ATP main-draw win in his career prior to Shanghai. Still, Wozniacki guided the debate toward a mutual conclusion: that Vacherot’s draw may indeed have been more improbable, yet Raducanu’s end result carries greater weight. “When you just talk about the result, the end result, i think winning the US Open is better than winning a 1000 Shanghai,” she said, drawing agreement from the room.
The debate also placed Raducanu’s recent career arc in perspective. Though she has not lifted a trophy since her breakthrough, she remains a relevant figure on tour. After a series of surgeries, she has climbed back to No. 28 in the rankings, with hopes that 2026 will mark a full return to form. Former pro Steve Johnson added balance to the conversation, noting, “I think time will tell. Raducanu has still been good… at least she has been relevant.”
In the end, Wozniacki and Isner reached a measured middle ground, agreeing on Vacherot’s improbable run while standing apart on the value of achievement. Isner concluded by saying, “Okay, if i think something’s more impressive, i’ll say it doesn’t matter men or women. That’s what we do on this pod. We’re truth tellers (laughs).”
