Sweeting ousts Karlovic in semis

Wild card faces Nishikori in final

 American Sweeting, who will face Japan's Kei Nishikori for the title, survived three break points in the fourth game and rallied from a 3-2 deficit in the tie-breaker with five consecutive points to take the first set.

Sweeting broke Croatian Karlovic's serve to take a 4-2 lead over the 2007 champion in the second set and closed out the match on serve.

In the other semifinal, Nishikori defeated Pablo Cuevas of Uruguay 6-3, 7-5 to reach his second ATP Tour final. He won the Delray Open in 2008.

Nishikori dropped serve in the fourth and sixth games of the second set but recovered by breaking Cuevas in the fifth and 11th games. Nishikori's serve was nearly broken again in the 12th game but he fought off two break points to close the match with a forehand volley. Nishikori is currently ranked 61st in the world, but would better Shuzo Matsuoka's career best of 46th if he defeats Sweeting.

Wozniacki advances

At Charleston in South Carolina, world number one Caroline Wozniacki defeated Serbia's Jelena Jankovic 6-4, 6-4 to set up a final meeting with Russian Elena Vesnina at the Family Circle Cup. Dane Wozniacki broke eighth-ranked Jankovic five times but also suffered three breaks of serve herself in a hard-fought encounter that lasted one hour 47 minutes.

Wozniacki is seeking her third tournament victory of the year after title triumphs at Indian Wells and Dubai.

Vesnina, ranked 56th in the world, has never won a WTA Tour event and will hope to break through in her fifth final.

The 24-year-old defeated China's Peng Shuai 7-6, 6-3, avenging her defeat in the quarterfinals in Doha in February. Vesnina has impressed this week, beating number two seed and defending champion Sam Stosur on her way to the final. Wozniacki defeated Vesnina in the final at New Haven in August 2009 and has a 4-1 record against the Russian.

Sania-Vesnina in final

Sania Mirza and her Russian partner Elena Vesnina notched up a straight-set win over Ji Zheng and Peng Shuai to enter the final of the Family Circle Cup.

The unseeded Indo-Russian pair won 6-2, 7-5 to make the finals and remain in contention for their second WTA title together after the triumph at Indian Wells last month.

Sania and Vesnina will now take on the fourth-seeded American duo of Bethannie Mattek-Sands and Meghann Shaughnessy.
