New Zealand's Marina Erakovic is tied at one set all with Japan's Ayumi Morita in a rain-interrupted Olympic tennis singles game so the game, originally scheduled for Sunday, will now go into a third day.
Erakovic won the first set 7-5 and was serving for the match at 7-6 in the second set tiebreaker when a forehand went out.
Morita took her chance, winning three consecutive points to win the tiebreak 9-7.
The winner plays China's big hope in the second round.
Li Na upset Russian No.3 seed Svetlana Kuznetsova 7-6, 6-4.
