NEW YORK—Serena Williams charged into the U.S. Open quarter-finals on Sunday but it may have come at a price as the six-times champion suffered a right ankle injury.
Williams, who twisted her left ankle during a quarter-final loss at the Australian Open, said she did not think the latest injury serious but added it was too soon to tell.
