Charleston, SC (SportsNetwork.com) - Madison Keys and Angelique Kerber each won their semifinal matches in straight sets to advance to Sunday's Family Circle Cup final in Charleston.

Keys, the No. 7 seed, advanced over qualifier Lucie Hradecka 6-1, 6-4 to advance to the clay court final.

Looking for her second career title and first in 2015, Keys accumulated seven more aces and leads the field with 26 so far this tournament.

In the second semifinal, the fifth-seeded Kerber topped fellow German Andrea Petkovic 6-4, 6-4. Petkovic, this event's defending champion and the No. 3 seed, had been 11-0 in her career in Charleston prior to Saturday's defeat.

Like Keys, Kerber is vying for her first tournament win this season. She has three in her career.

Kerber owns a 2-1 record against Keys, but Keys won the most recent meeting in the 2014 final at Eastbourne.

Sunday's winner will receive $124,000.
