Kiki's shot spot selection is very poor.
She kept pushing the ball in the middle for her opponent to hit the angles. That's not going to work against better players. Yamstreka places her balls far better.
She's always nervous in Paris. Remember when she was a form horse in 2017 and she barely scraped by most of her rounds with the exception of Errani - and I was at that match on Lenglen, and Errani was giving her plenty of DFs and puff second serves to be pummeled with ease.
Let's see how she can fare against a much tougher clay court opponent in the 2nd round. Should be a good match.
