Zheng Qinwen's calm reaction to line call

Zheng Qinwen kept calm on disadvantageous line call in the game against Victoria Mboko: "It was very clear from the ball mark that it was out, but the umpire called it in. The same thing happened last year, and I couldn’t hold back my tears. This year, I handled my emotions much better — I just let that point go and quickly refocused on the next one.”
