Despite being a very difficult year for Jo (knee injury, unwanted loss of her best ever coach Zavialoff, heart rate issue...) Jo still ended 2020 as the top WTA Brit even on her 2020 performance alone (check please) eg 2020 ranking points, 2020 prize money... Jo also came very close to taking out Azarenka at the W&S semi (in NY) (down to a few key BPs) which would have given her the title, with the withdrawal of Osaka.
