Keys, Hradecka surprise semifinalists at the Family Circle (Yahoo Sports)

Madison Keys and Lucie Hradecka are finding their games on clay and are both surprise semifinalists at the Family Circle Cup. Keys, the seventh seed, put on a dominating show to beat fellow American and one-time training partner Lauren Davis, 6-2, 6-2. Hradecka, a qualifier from the Czech Republic, topped her second seeded player in as many days, knocking out No. 4 seed Sara Errani, 6-2, 6-4. Third-seeded Andrea Petkovic brought some stability – and as defending champion, a familiar name – into the semifinals with a 2-6, 6-3, 6-1 victory over qualifier Danka Kovinic.
