NEW YORK -- Thanks to the rain and the schedule-makers, Serena Williams got an unexpected day off Wednesday at the US Open.
On a gray, drippy day at Flushing Meadows, tournament officials postponed the defending champion's second-round match against Galina Voskoboeva, along with seven others on the women's singles slate.
With the storm bearing down in the early afternoon, video monitors around the Billie Jean King National Tennis Center warned fans to seek shelter and avoid trees because of potential lightning, although thousands of ticket holders were milling about without much concern for severe weather.
They're used to this scene.
The US Open has wrapped up a day late for five straight years because of rain delays.
This year, the U.S. Tennis Association announced it would build a roof over Arthur Ashe Stadium as part of a renovation project that will cost $550 million. The roof could be ready by 2016, or 2017 at the latest.
Even that wouldn't have alleviated a first-week logjam the likes of which the tournament faced Wednesday, with a full slate of matches in singles along with men's, women's and mixed doubles.
In all, there were seven men's doubles, two mixed doubles and 11 women's doubles matches postponed, including one involving formerly retired five-time major winner Martina Hingis, who is teaming with Daniela Hantuchova.
