No.1 seed Bublik's Round of 16 clash with Quentin Halys was interrupted by rain, and the Frenchman got the better of his opponent when play resumed.

Halys returned to the court serving at 5-6 in the deciding set and held firm to claim his 6-7 (4-7) 6-4 7-6 (7-5) victory on his second match point against the reigning champion.

After Bublik fell, the other big names followed.

Ruud also took the first set of his match, but Juan Manuel Cerundolo earned a hard-fought victory to make it through to the semi-finals.

The Argentinian triumphed 3-6 7-5 6-2, despite trailing 4-2 at one stage of the second set, and completed a stunning turnaround against the No.2 seed in two hours and 15 minutes on the court.

Cerundolo will now face Raphael Collingnon in the final four after the Belgian sank Vacherot in three sets.

Collingnon held his nerve in the first-set tie-break and did not let his head drop after losing the second set, claiming a 7-6 (9-7) 4-6 7-5 win.

Stefanos Tsitsipas completed the spectacular day on the clay courts, as he reached his first semi-final since winning in Dubai last year as he knocked out No.4 seed Rinderknech.

The Greek upset Rinderknech 6-3 3-6 6-3 in one hour and 41 minutes, and will face Aleksandr Shevchenko, who beat Halys in the last eight, for a place in the final.
