Nadal’s domination was so overwhelming that Thiem didn’t get on the scoreboard until the 10th game.
The Austrian had raised prospects of a tight encounter in the semifinal after beating two-time champion Novak Djokovic on Thursday. However, he wilted under Nadal’s pressure dropping his serve thrice in the first set.
He managed to hold his serve for the first time in the fourth game of the second set. However, by then Nadal was in complete control. The 16-time-Grand Slam winner sealed his win in just 68 minutes.
“Here I think I played great... It has been a great day for me, and a very good result against a very difficult rival,” said Nadal.
The Spaniard is now just two wins away from a record 31st Masters title.
In other quarterfinal matches, Dimitrov beat David Goffin Dimitrov 6-4, 7-6 (7/5) while third seed Alexander Zverev defeated Richard Gasquet 4-6, 6-2, 7-5. Zverev now faces Kei Nishikori who beat second seed Marin Cilic 6-4, 6-7 (1/7), 6-3.
