Local hope Serena Williams, battling the wind as much as her opponent, eased into the quarter-finals of the U.S. Tennis Open on Monday with a 6-3 6-4 win over Serbia's former world number one Ana Ivanovic.
Both players struggled with their serves and ground strokes on a gusty Arthur Ashe Stadium but it was the American who fared better.
Williams, a three-time winner at Flushing Meadows, will play Anastasia Pavlyuchenkova in the quarter-finals, after the 17th-seeded Russian upset seventh seeded Italian Francesca Schiavone in three sets.
