A day after both survived draining three-set victories, Hingis was the one with the recovery powers.

Nishikiori followed up that impressive performance with another three-set victory, this time over Santiago Giraldo, 7-6, 4-6, 6-3.

Another break in the ninth game and Edberg was poised for an easy three-set victory.

Navratilova, seeded first and the clear favorite, reaffirmed her status with an enthralling three-set victory in which the final two sets were decided by tiebreakers.

Haas's tendinitis-plagued arm swelled up Friday night after his third consecutive three-set victory here.

Today, McEnroe served, volleyed and cursed to his third three-set victory over Sanchez without a loss.

He played against Seppi the next day but struggled to a three-set victory, trailing 5-1 during the second set and looking out of sorts.

"Of course, it was fantastic to be out there again," Navratilova said after a three-set victory.

But trailing by one set and 3-5 in the second, she suddenly found her range and stormed back to a three-set victory.

She played just one match this summer - in Toronto - and withdrew after hobbling to a three-set victory.
