World No.1 Iga Swiatek's commitment to mental health advocacy is well-documented. The Polish star's commitment to the cause took another step on Sunday in the aftermath of her three-set defeat at the hands of Barbora Krejcikova in the final of the Agel Open: In her on-court interview, Swiatek revealed that she'll donated her prize money from the event to a Polish mental health non-profit.

Open about her work with sports psychologist Daria Abramowicz since her breakthrough win at Roland Garros in 2020, Swiatek first donated prize money to a mental health charity last year during the BNP Paribas Open in honor of World Mental Health Day, which is celebrated annually on Oct. 10.

Now World No.1, the 21-year-old made this year's commitment as part an emotional on-court runner-up speech in Ostrava, where she also took the time to thank the legions of fans who came from Poland to support her at the event. 

While Swiatek has yet to announce what charity will receive the contribution, she says she has a few in mind, and expanded upon her reasonings for doing so in her post-match press conference. 

"I really wanted to play well here to have a big amount of money to donate ... and I'm pretty happy that I could do that," Swiatek said.

"I really want to spread awareness and let people know that they can use the help if they need it, or help others if they have resources. I'm pretty happy to use my position that way."

Update: In a post on social media, Swiatek confirmed she would be donating her prize money to a Polish charity that helps children with mental issues. "I encourage everyone to donate even small amounts to one of the charities because together we can make a difference," Swiatek wrote. 

Swiatek also invited fans to submit questions for her and her sports psychologist, Daria Abramowicz, and the two would answer them on Instagram after the tournament in San Diego.
