PARIS - The No 4 seed Rafael Nadal moved a step closer to his 10th success at Roland Garros as his fellow Spanish Pablo Carreno Busta withdrew due to an injury after 51 minutes of play in the quarterfinals here on Wednesday.

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.
