As Rafael Nadal aims to win a 11th French Open, he comes up against a resurgent Juan Martin del Potro. Nadal overcame Diego Schwartzmann of Argentina in four sets after a rain delay stretched the quarter-finals to two days.

Similarly, del Potro too had to wait till day 12 of the French Open to vanquish Marin Cilic in four.

Surprise package Marco Cecchinato is into the semi-finals as he beat former world number 1 Novak Djokovic in four sets. Cecchinato’s reward will be a match against Dominic Thiem, who brushed aside second seed Alexander Zverev.
