Nadal will meet Dominic Thiem in the semifinals, as the Austrian promising star shocked defending champion Novak Djokovic in three straight sets.

Nadal met little resistence from his Spanish compatriot in their fourth duel although he was broken twice in the third and seventh games of the 32-minute opening set.

The 20th-seeded Carreno Busta retired when Nadal was leading 6-2, 2-0. The "King of Clay" is now 22-1 on clay this year.
