Paris Olympics champion Zheng Qinwen showed significant progress in her mental game with a come-from-behind win in the US Open first round against Amanda Anisimova. Despite being on the back foot early on, world number seven Zheng managed to secure a 4-6, 6-4, 6-2 victory over her American opponent.
Zheng, who is the first Olympic singles champion from China, was particularly happy to build on her Olympic success.
