(Reuters) - Top seed Karolina Pliskova started Friday in the last-16 at the inaugural Zhengzhou Open and ended the day in the semi-finals after defeating Polona Hercog and Sofia Kenin in succession.
Pliskova's match against Slovenian Hercog was suspended on Wednesday due to rain with the score at 6-3 2-5 and she only returned to court two days later after rain washed out Thursday's matches.
