Seeds Karolina Pliskova and Dominika Cibulkova advanced to the third round as rain wreaked havoc at the Miami Open.
Czech second seed Pliskova and fourth seed Cibulkova both won in straight sets before play was cancelled due to bad weather in Miami on Thursday.
Reigning French Open champion Garbine Muguruza had just lost the opening set 6-0 to Christina McHale when WTA tournament officials succumbed to the relentless rain.
Agnieszka Radwanska Caroline Wozniacki made it through their second-round encounters.
PLISKOVA STAYS HOT IN WET MIAMI
A semi-finalist at Indian Wells last week, Pliskova continued where she left off with a 6-1 6-3 demolition of Madison Brengle.
Pliskova needed less than an hour to book her spot in the third round, tallying 27 winners and 30 unforced errors as she converted five of her break point chances.
Next up is 27th seed Yulia Putintseva, who defeated Carina Witthoeft 6-4 6-4.
