'I'm at breaking point' - Kasatkina ends season early

World number 19 Daria Kasatkina says she is at "breaking point" and has ended her season early, describing the schedule as "too much, mentally and emotionally".

The 28-year-old switched nationality from Russia to Australia in March, having criticised her country's LGBTQ+ laws and the war in Ukraine.

She struggled for form this year, failing to win a title and finishing with a 19-21 record.

Kasatkina said the emotional stress of her nationality switch contributed to her struggles, including not seeing her father for four years.

"I've been far from fine for a long time and, truth be told, my results and performances show that," she wrote in a lengthy statement., external

"I am at breaking point and sadly I am not alone.

"Add in to the mix the emotional and mental stress related to my nationality switch and there is only so much I can deal with and take as an individual woman.

"If this makes me weak, then so be it, I'm weak.

"However, I know I am strong and will get stronger by being away and recharging.

"It's time I listened to myself for a change."
