Previously, she had advanced over Ons Jabeur via retirement in the second round of Toronto. It puts Zheng into her third tour-level quarterfinal of 2022, and second at WTA 500 level or above.”It was a big match for me. Even though the score was like this, there were a lot of emotions for me in this match and I’m very proud of myself. It’s not a surprise – I always knew I had the level, I just had to make it,” said Zheng.The teenager’s overall record this year is now 34-15, and 19-15 at the tour level. Having ended 2021 at No 143, she has risen to a career-high this week of No 36.
