"It wasn't a tough loss, they were just the better team," Huber said. "They have so much experience and have won so many titles, so it was an honour to play them."
Black and Huber will join up in the final of the women's doubles when they play American Lisa Raymond and Australian Sam Stosur, the 10th seeds.
