Geneva - Top-seeded Stan Wawrinka will play Marin Cilic for the Geneva Open title after both advanced from the semi-finals on Friday.
French Open champion Wawrinka beat Lukas Rosol of the Czech Republic 6-2, 4-6, 6-3 to reach his first final in his native Switzerland for 11 years.
Third-seeded Cilic eased past David Ferrer 7-5, 7-5 to get his first clay-court victory over the second-seeded Spaniard at the third attempt.

Wawrinka is 9-0 in finals over the past three seasons.
