GENEVA — Defending champion Stan Wawrinka advanced to the Geneva Open final by beating unseeded Andrey Kuznetsov 6-3, 7-6 (4) Friday.
The top-seeded Wawrinka will face qualifier Mischa Zverev of Germany, who has peaked this week after a poor clay-court season and beat second-seeded Kei Nishikori 6-4, 3-6, 6-3 in the other semifinal.
Wawrinka, the US Open champion, will seek a 16th career singles titles and a seventh on clay, including the 2015 French Open. Zverev is looking for his first title at age 29.
Still, Zverev beat the third-ranked Wawrinka when they last played, at the Swiss Indoors in Basel in October.
The final on Saturday will be only the second of Zverev's injury-hit career. The Russian-born left-hander was runner-up at Metz, France, in September 2010.
Tsonga-Berdych final in Lyon
Second-seeded Jo-Wilfried Tsonga beat Nikoloz Basilashvili of Georgia at the Lyon Open Friday to reach his first clay-court final.
Tsonga hit 14 aces and saved eight of 10 break points to win 6-2, 3-6, 6-1.
The Frenchman, who has reached 25 ATP finals on other surfaces, will face third-seeded Tomas Berdych Saturday.
Berdych beat top-seeded Milos Raonic 7-6 (5), 7-6 (2) in the other semifinal.
Raonic, who hit 17 aces, appeared to have got back into the match when he got the first break early in the second set, but Berdych broke back and the Czech player went on to clinch his second tiebreak.
Gavrilova to meet Stosur
Daria Gavrilova booked an all-Australian final with Sam Stosur at the Strasbourg Internationals when she beat defending champion and local favorite Caroline Garcia 6-4, 6-2 Friday.
Stosur beat China's Peng Shuai 7-6(0) 6-4 to advance, with the winner of Saturday's final also set to secure the Australian No. 1 spot just ahead of Sunday's French Open.
Stosur has owned that spot for 450 straight weeks since October 2008.
Seventh seed Gavrilova dropped only five points on serve in the first set in a solid performance against Garcia, the fifth seed.
Bertens-Krejcikova final
Defending champion Kiki Bertens will face Czech qualifier Barbora Krejcikova in the final of the Nuremberg Cup.
The 254th-ranked Krejcikova upset Sorana Cirstea 6-4, 4-6, 6-0 to end the Romanian's debut at the clay-court tournament, and Bertens advanced in the other semifinal on Friday when Misaki Doi became the sixth player to retire.
Bertens was leading 6-2, 0-1 when Doi retired with a right abdominal injury. The 64th-ranked Japanese player progressed in the first round and quarterfinals when injuries forced Maria Sakkari and then Yaroslava Shvedova to retire.
Laura Siegemund, Eugenie Bouchard, and Alexandra Cadantu also withdrew with injuries from the French Open warmup.
Bertens, who defeated Mariana Duque-Marino 6-2, 6-2 in last year's final, has a 12-1 all-time win-loss record in Nuremberg.
Krejcikova is going for her first title. — Agencies
