New Haven, Connecticut: World No. 1 Caroline Wozniacki won for the first time in over a month, convincingly beating Polona Hercog in the New Haven Open, with Tuesday's play affected by an earthquake.
Wozniacki, who has never lost a match in New Haven, won 6-3, 6-0 and will face Christina McHale in the quarterfinals, a week after being beaten by the 19-year-old in their only other meeting.
In other results, Russia's Elena Vesnina beat seventh-seeded Jelena Jankovic in a first-round match that was interrupted by a distant earthquake that forced the evacuation of fans and players. Vesnina will play Spain's Anabel Media-Garrigues in the second round.
