UMAG, Croatia -- Fernando Verdasco will take on fellow Spaniard Marcel Granollers, while home favorite Marin Cilic will face defending champion Alexandr Dolgopolov in the semifinals of the Croatia Open on Saturday.
For the first time since the inaugural tournament in 1990, the top four seeds will compete for a place in the final.
Verdasco, the 2008 champion, saved all six break points he faced and converted 3 of 7 break chances.
"Obviously, I am very happy with the way I progress here," Verdasco said. "Being in the semifinals is a very good thing. I played really good today."
Fourth-seeded Granollers lost the first set in just 31 minutes. He had a 5-3 lead in the third set, but then lost serve before breaking again for the victory.
"I needed a few games in the beginning to adjust," Cilic said. "I played very well when I needed it."
