Torrential rain forced Rafael Nadal and Novak Djokovic's quarter-finals at the French Open to be delayed until Wednesday.
Play was held up for over three hours on Tuesday before finally resuming at 18:45 local time (16:45 GMT) with the first two women's quarter-finals at Roland Garros.
Switzerland's Timea Bacsinszky beat 13th-seeded Mladenovic 6-4, 6-4 in a match which was twice delayed by rain.
Teenager Jelena Ostapenko advanced to the semifinals of the French Open by rallying past former No. 1 Caroline Wozniacki, 4-6, 6-2, 6-2.
Nine-time champion Nadal is due to take on compatriot Pablo Carreno Busta, while title-holder Djokovic faces sixth seed Dominic Thiem in a repeat of last year's semi-final.
As a result of the downpours, all four men's quarter- finals will be played on Wedneday with Andy Murray against Kei Nishikori and Stan Wawrinka facing Marin Cilic.
