Defending champion Mikhail Youzhny was sent crashing out of the Credit Agricole Suisse Open after being beaten 3-6 6-1 6-4 by Robin Haase.
In a repeat of last year's final, Dutchman Haase came from behind to get past his top-seeded Russian opponent in Gstaad. In the semi-finals he will face Juan Monaco, who defeated Thomaz Bellucci of Brazil 7-6 (7-1) 6-1.
"I beat him this year so I knew I could do it. Once I went a break down in the first set, I started playing better," Haase said.
"In the second, my ball was 20 kph faster and a metre deeper. I was feeling good and serving better. In the third I couldn't do anything wrong until 5-2.
"I felt confident about the match but then I made some mistakes and got nervous. At 5-4, 4-0 you think it's done but then I had a double-fault. I got nervous but I closed it out in the end."
The other final-four contest pits fourth seed Fernando Verdasco against fellow Spaniard Pablo Andujar. Verdasco played twice on Friday, booking his semi-final place by overcoming Viktor Troicki 6-4 6-7 (7-9) 6-1.
Serbian wild card Troicki was playing in his first tournament since his doping ban expired and could not extend his run to the last four.
Verdasco had earlier he had beaten Jan-Lennard Struff 3-6 6-3 7-6 (7-3) in the second round, the pair having resumed at 1-1 in the third set. Andujar beat compatriot Marcel Granollers, the second seed, 7-5 6-3.
