In Moscow, the US trailed Russia 2-0 after Williams lost 5-7 6-4 6-2 to Myskina and Mashona Washington was beaten 7-5 6-4 by Dementieva on Saturday.
"It was much harder yesterday as Williams is a player of a much higher class," said Myskina after beating Craybas.
"Washington and Craybas are almost even and I should beat any of them as it will be a disaster to miss such a great chance to win."
Williams was happy enough to get back to winning ways against Dementieva.
"Yesterday it was tough," said the American. "It was so difficult to find energy after so many weeks of playing. I definitely was not my normal self.
"Last night I wanted to win for the team and that was important.
"But it's definitely hard because it's not just one person - it's a disappointment for the whole team."
Vera Douchevina and Dinara Safina completed a 4-1 victory for the hosts when they beat Venus Williams and Corina Morariu 6-1 7-5 in the doubles.
Russia and France clashed in last year's final, the Russians winning 3-2 in Moscow, and Mauresmo is keen for revenge.
"That's good," she said. "We've faced them several times over there - now, we get to host them."
