Venus Williams lost in the second round of the US Open for a third consecutive year with defeat by China's Zheng Jie.
The two-time champion went down 6-3 2-6 7-6 (7-5) in three hours and two minutes, the joint fifth-longest women's match in the event's history.
Her sister Serena's second-round match was postponed because of rain.
But third seed Agnieszka Radwanska and fifth seed Li Na advanced before the showers arrived, while sixth seed Juan Martin del Potro also went through.
China's Li will next play Britain's Laura Robson, who beat Caroline Garcia of France 6-4 7-6 (7-5).

Blake to retire
"To James Blake: Thx for the memories, representing our sport in a positive way. Enjoy your time with family but your @usopen isn't over yet!"
"It's my favourite tournament. Thank you supporting me, for staying," said 2009 champion Del Potro after his match delayed the start of the night session - and Andy Murray's title defence.
The Argentine said his next opponent Lleyton Hewitt was "maybe the toughest opponent without seeding in the field."
