Wikipedia - Zarina Diyas
Zarina Diyas (born 18 October 1993) is a Kazakhstani professional tennis player. She has been ranked as high as No. 31 in the world by the Women's Tennis Association (WTA). In her career, Diyas won one WTA Tour singles title, at the 2017 Japan Women's Open, as well as nine singles titles on the ITF Women's Circuit.
Diyas mostly played on the ITF Circuit until 2014, her breakthrough season. During that year, she started outside the top 150, before progressing into the top 40 by September. This helped her enter tournaments on the WTA Tour more consistently, though she still plays ITF tournaments. She is one of the most successful female tennis players representing Kazakhstan, along with Elena Rybakina and Yulia Putintseva.
Diyas became a member of the Kazakhstan Fed Cup team in 2011 and is tied for her country's most singles wins with Yaroslava Shvedova, but with a much better winning percentage.
