Svetlana Kuznetsova eased through to the last 16 of the Washington Open on Monday with a 6-2, 6-1 victory over American Kristie Ahn.

The two-time Grand Slam champion, a winner in the American capital in 2014, was impressive throughout, firing down six aces as she dropped just seven points on serve the whole match.

The Russian will face the winner of the match number four seed Ekaterina Makarova and Ana Bogdan in the next round.

Also through was Britain’s two Katie Boulter, who upset fifth seed Aleksandra Krunic in straight sets.

The 21-year-old Boulter dispatched the 47th ranked Serb 6-2, 6-0 in just over an over an hour to set up a tie against Allie Kiick of the US on Wednesday.

Sixth seed Belinda Bencic was leading Britain’s Harriet Dart 7-5, 4-2 when play was eventually suspended.
