Three-time former champion Venus Williams survived a hair-raising third round match against Akiko Morigami of Japan on Monday, winning 6-2, 3-6, 7-5 but looking far from comfortable.
The American former world number one had seemed to be cruising when she eased to a convincing first set lead in the match which started on Saturday.
But a double break by the Japanese player gave her a 4-1 lead before the weather intervened and halted play until Monday.
Williams kept herself in the second set by saving six set points in the seventh game and then breaking in the next. But Morigami unleashed some accurate shots down the line finally to snatch the set.
Seemingly intent on making it difficult for herself, Williams dropped serve in the eighth game of the third, before breaking back.
In the end it was a mistake by Morigami that handed Williams the match, with the Japanese player putting her return into the net. Williams jumped up and down in celebration and, most likely, relief.
