Top-seeded Australian Samantha Stosur has set up a semi-final against Ana Ivanovic in Moscow, but Lleyton Hewitt lost to Nicolas Almagro in Stockholm.
Stosur eased into the Kremlin Cup semi-finals with a 6-1, 6-3 win over Czech Klara Zakopalova.
Stosur, currently ninth in the WTA rankings, was in command from the start breaking Zakopalova's serve three times for a one-set lead in 27 minutes.
In the second set, Stosur was trailing 3-1 after Zakopalova broke in the third game. But the 2011 US Open champion then broke back twice to win the set and the match.
Stosur will now face Ivanovic, the 2008 French Open champion and fourth seed, who also advanced into the semi-finals beating unheralded compatriot Vesna Dolonc 6-4 6-1 in an all-Serbian quarter-final.
"It's going to be a tough match as we didn't play each other for a long time," Stosur said about Sunday's semi-final (AEDT).
"I'm going to be ready for anything. I shall concentrate on my own game, be ready to work hard and be also ready for long rallies."
Third seed Caroline Wozniacki defeated defending champion Dominika Cibulkova of Slovakia and will face Sofia Arvidsson of Sweden in the other semi-final.
Hewitt, meanwhile, was downed 6-1, 6-4 by Spaniard Almagro in just over an hour in the Stockholm Open.
The first set was a disaster for Hewitt, winning just 30% of points on his second serve as he was swiftly cast aside.
The second stanza was much more competitive but though the former world number one created four break point opportunities to Almagro's three, he could not force a deciding set.
Marinko Matosevic also lost on Saturday (AEDT) in the Vienna Open, going out 6-2, 6-2 to top-seed Juan Martin Del Potro.
