After taking the first set, Zheng was forced to a medical timeout at 0-3 in the second set where she received treatment for back problems.

She then went out to the dressing room and came back with a wrapped thigh.

- The leg was not okay either, but compared to the stomach pain it was nothing, says Zheng and tells that she has major menstrual problems.

Hard to run and push off

- The first day is always so tough and to then practice sports is difficult but I can not go against nature, Zheng says according to Reuters.

- I wish I was a man on the track in those moments so that I do not have to be tormented in this way, but I can not, says Zheng who finds it difficult to run and push away in the strokes.

- I hope to be in perfect shape next time we meet, says the 74-ranked Chinese who made his Grand Slam debut as recently as in Australia in January.

Iga Switek, who has taken over women's tennis since Ash Barty retired last winter, took her 32nd straight victory and storms towards her second title in Paris - two years after the breakthrough with the bang title 2020.
