WTA roundup: Madison Keys fights into next round in Charleston

Despite her opponent saving seven match points, No. 2 seed Madison Keys pushed past Caroline Dolehide 6-3, 7-6 (4) in an All-American second-round battle at the Credit One Charleston (S.C.) Open on Tuesday.

Dolehide saved four match points in the ninth game of the second set and two more in the 10th to force a 5-5 tie. She saved one more in the tiebreaker before Keys, the 2019 Charleston champion, put the match away.

Defending champion Danielle Collins, the No. 7 seed, also advanced out of the second round and had 26 winners and five aces while beating fellow American Robin Montgomery 6-3, 6-1.

In first-round results, winners included Americans Sofia Kenin, Hailey Baptiste, Louisa Chirico, Ann Li and Lauren Davis; China's Shuai Zhang; Maria Sakkari of Greece; and Iryna Shymanovich of Belarus.
