Melbourne - Dayana Yastremska's coach Sascha Bajin blasted her critics on Thursday, saying he wanted to "shut some people up" after former world No 1 Caroline Wozniacki accused the Ukrainian of faking an injury.
The 19-year-old was one game away from defeat against the former world No 1 at the Australian Open on Wednesday when she called for a medical timeout, and a trainer came on court to strap her left thigh.
She managed to save a handful of match points on resumption before the Dane wrapped up a tough 7-5, 7-5 victory.
Asked about the timeout in her post-match press conference, Wozniacki replied: "Obviously she tried to break my rhythm. And at 5-4 I don't think there is anything wrong. She was running just fine.
"So that's a trick that she's done before, and I knew that it was coming," she added.
Bajin, who used to coach two-time Grand Slam winner Naomi Osaka, fired back.
Reaction on social media overwhelmingly backed Wozniacki, with users noting Yastremska, who won two singles titles last year, had used the timeout tactic before at crucial moments.
said one person replying to Bajin, in sentiments echoed by others.
Wozniacki, in her final tournament before retiring, plays Tunisia's Ons Jabeur in the third round on Friday.
