World number one Caroline Wozniacki eased into the third round of the New Haven Open as play continued after the earlier evacuation following the after shocks of the earthquake that has hit the east coast.
Play was suspended for two hours during the match between Russia's Elena Vesnina and Serbian former world number one Jelena Jankovic.
During the break stands were checked for any structural damage but after getting the all-clear, the match resumed with Vesnina triumphing in three sets.
Wozniacki was then on court as she looked for confidence-boosting results following recent early losses in Toronto and Cincinnati with the US Open, for which she is seeded first, just days away.
The Dane took advantage of her break points against Slovenia's Polona Hercog, winning four out of five, to cruise through 6-3 6-0.
Third seed Francesca Schiavone also enjoyed a straight-sets victory, beating Monica Niculescu 6-2 6-1.
However, fifth seed Agnieszka Radwanska went out, beaten by Petra Cetkovska. The Czech won 6-4 5-7 6-3.
Christina McHale, Wozniacki's Cincinnati conqueror last week, continued her good form as she downed Carla Suarez Navarro 6-2 6-2.
Vesnina had earlier beaten Jankovic in their first-round match, the Russian edging matters 6-4 2-6 6-4 as neither player appeared rocked by their enforced delay.
