"I don't feel like we've won because today was such a short day," Shvedova said about finishing the match a day later on Arthur Ashe Stadium center court.
King and Shvedova trailed the second seeds 4-5, 0-15 in the decisive third set when play was halted Sunday due to rain.
But King, serving the 10th game, saved match point with a forehand winner down the line and held serve to send the match to a tiebreaker.
"Usually great pairs pair together for a long time to know each other, and they really get a feel for each other and become a true team," said King.
"We had that from the beginning. We bonded together so well and we're also good friends, which helped."
Huber and Petrova were gracious in defeat.
"We were trying our hardest and to give all today," said Petrova. "And absolutely no regrets."
