Yesterday, Collins disclosed on the Tennis Channel program that during her preparations for a live broadcast, Mutai, training nearby, whistled flirtatiously at her, and she recounted the interaction with a playful tone.
Collins said, "I told him right then, 'If you want to flirt with me like that, you better bring something substantial.' Some believe victory depends on height, others think it hinges on character, but in reality, it's about a powerful forehand and a strong serve."

The American star then mentioned the controversy sparked by her previous online comments about "preferring tall men." She revealed that after those remarks spread widely online, Mutai quietly unfollowed her. "Come on, you have to understand me, I'm 1.78 meters tall, it's just a personal preference, perfectly normal, but it bothered him," Collins said. "It's kind of funny because when I said I'm not interested in 'short kings,' he unfollowed me."
Collins also added that just last night, Mutai privately messaged her, asking if she had seen the powerful shots he made in the second round of the match. When the host asked whether Mutai had the potential to advance far in the tournament, Collins gave an ambiguous reply: "I don't think he has that chance... he would need to overcome many obstacles, but who knows, let's see..."

After this interview aired, it quickly sparked widespread discussion on social media. Mutai evidently saw the content and soon posted a strongly worded tweet on social platforms, directly criticizing Collins and the Tennis Channel.
"I never followed you, so how could I unfollow you?" Mutai retorted sharply in the tweet. "Tennis Channel, how can you allow someone who spouts nonsense like this on your program? You were the one who suggested partnering with me in mixed doubles; I never followed you. You want to say sensational things to get people talking about you, but first you need to learn self-respect, so you don't do foolish things just to gain others' approval. Tennis Channel, you really hired a great journalist."
Mutai's response was full of火药味, directly denying the "unfollow" claim and angrily accusing Collins of fabricating stories to seek attention.

This public exchange quickly sparked heated debate. Sports commentators offered different perspectives. Veteran tennis commentator James Blake remarked in an interview: "This was originally a minor incident; small occurrences on the training ground are common. Collins brought it into the live broadcast, presenting it in a lighthearted, teasing manner, which isn't unusual in sports programs. But Mutai's response was clearly serious and angry, escalating a玩笑 into a personal attack. Both sides have their own versions, especially regarding the 'unfollow' detail, which has now become a Rashomon situation."
Another European sports journalist analyzed: "Collins is known for her straightforward, candid personality; she never hides her thoughts, whether on or off the court. Mutai, as a young player, is evidently very sensitive to such public teasing, especially regarding topics like height. His anger is understandable, but the wording was indeed excessive. This isn't beneficial for either of them, and public pressure might affect their performance."

On social media, fans split into two camps, arguing incessantly.
Some网友 supported Collins, believing she was just joking: "Collins merely shared a funny story on the program; Mutai is too sensitive. She only expressed a personal preference without insulting anyone."
Other网友 commented, "Mutai's response is too harsh, directly saying 'spouts nonsense'? That seems petty. It could have been laughed off, but now it's turned ugly."

Yet many网友 sided with Mutai, arguing Collins's remarks were disrespectful: "If genders were reversed, a male player publicly teasing a female player's height and saying 'I'm not interested in short ones,' he would have been热搜骂. Collins is indeed somewhat double-standard." Some网友 expressed support: "Mutai stated clearly he never followed her, so Collins's 'unfollow' claim is fabricated? Creating stories for program attention isn't professional."
Neutral网友 expressed frustration: "Here we go again, the drama in tennis now rivals the matches. Can we focus on playing and let performance speak?"
How this "series" triggered by a whistle will develop—whether both sides will quiet down or engage in another round of public exchange—is being watched closely.(Source: Tennis Home Author: Lu Xiaotian)
