Tim Tszyu was locked in the biggest fight of his career, but it was his sister who became the main talking point out of his WBO super welterweight title fight against Brian Mendoza.
As Tszyu and Mendoza battled it out at the Gold Coast Convention & Exhibition Centre, fans watching on grew increasingly frustrated.

And it had nothing to do with what was going on inside the ring.
Instead it was Tszyu’s sister Anastasia who was getting under the skin of every boxing fan watching on.
While many in attendance were in the corner of the Aussie, Anastasia’s allegiance stuck out more than most as she shouted out to her brother constantly throughout the fight.
The high-pitched shrieks of her commands to “break him down” left those watching on searching for the mute button.
TAB wrote on X: “What hurts your head more? Copping a jab or listening to that screaming?”

Another added: “Can someone shut the rat up in the crowd.”
Who is Anastasia Tsyzu?
The young sister of Tim, Anastasia was born in 2002 and is said to reside in Sydney, Australia.
Her social media profiles see her constantly share and promote her brother’s boxing videos while she also shares a lot of posts with her family.
She celebrated her 21st birthday in September, uploading multiple photos on Facebook with the caption: “21 with all my favourite people”.
Tszyu confirmed he is fighting in Australia for the final time when he steps into the ring on Sunday.
Defending his WBO super welterweight belt for the first time, he entered as the red-hot favourite against Mendoza.
Tszyu is in career-best form, having defeated Tony Harrison in a statement performance in March before knocking out Carlos Ocampo in a minute.
Tszyu is hungry for more after he was awarded world champion status when Jermell Charlo moved up divisions to fight Saul ‘Canelo’ Alvarez and was stripped by the WBO.
Mendoza has clawed his way off the boxing scrap heap with upset knockout wins over Jeison Rosario and Sebastian Fundora to set up a fight with Tszyu.
