China's big hope for Olympic doubles gold Jie Zheng continued her golden run in the Wimbledon ladies' singles by beating her third seed, Hungary's Agnes Szavay, to move through to the last eight.

The 24-year-old, conqueror of top seed Ana Ivanovic in the previous round and Slovakia's Dominika Cibulkova in the first round, raced through the match 6-3, 6-4, and meaning she has yet to drop a set in her four matches so far.

Svazay struggled in the early games with her favoured serve, but both players worked their games well, with Szavay shooting through strong forehands and Zheng displaying her wickedly, whippy-fast backhand on more than a few occasions.

There was only one break of serve in the set, by Zheng for a 5-3 lead. And the Chinese woman needed only one attempt for the set, securing it with her only ace of the entire match.

Zheng - a doubles specialist, who is ranked just 133 in singles and needed a wild card to play here - was taking control of the match thanks to some superb punched forehand drives, where she let the ball bounce just a fraction higher, then powered the ball into a bottom corner of the court.

Szavay fought back well in the second set, securing and banking her first break point in the fourth game to take a 3-1 lead. She made better use of the width of the court, running Zheng from one side to the other, to reach a 4-1 lead.

But this was as far as Hungary's nascent star got. While she showed flashes of great skill and shot placement, she could not put together a string of such strokes to get a grip of the match.
