TOKYO, Japan - US Open champions Liezel Huber and Lisa Raymond and runners-up Vania King and Yaroslava Shvedova were each victorious at the Toray Pan Pacific Open on Tuesday in the first match for each duo since their memorable final at Flushing Meadows.

Huber and Raymond had the easier path to the quarterfinals, handling Japanese wildcards Rika Fujiwara and Ayumi Morita, 61 63. "Great crowd out watching our doubles today," Raymond tweeted. "Fun getting back out there!"

Although this is the first time the Americans are playing this event together, Raymond has quite a history here with other partners, highlighted by two titles alongside Samantha Stosur and two with Rennae Stubbs. Next up for the No.1 seeds are Chan Yung-Jan and Julia Goerges.

As for third-seeded King and Shvedova, they survived a battle with Hsieh Su-Wei and Zheng Jie. King and Shvedova started the match in a 5-0 hole, eventually losing the first set, 6-2. They were a game away from defeat at 5-4 in the second but Shvedova held serve. They also faced a 4-2 deficit in the tie-break before reeling off five straight points. Then in the match tie-break, King and Shvedova's 5-1 lead evaporated into a 9-9 tie before they prevailed, 26 76(4) 119.

It was an especially good day for King, a champion here in 2008 with Nadia Petrova, as she upset No.11 seed Anastasia Pavlyuchenkova in singles.

Wednesday's doubles schedule is highlighted by second-seeded Gisela Dulko and Flavia Pennetta facing off with defending champions Iveta Benesova and Barbora Zahlavova Strycova.
