Moscow: Fourth seed Ana Ivanovic defeated qualifier Vesna Dolonc, ranked 160 in the world, to book an encounter with top-seeded Sam Stosur in the Kremlin Cup semifinals here.
The all-Serbian quarterfinal Friday lasted for just over an hour before the former World No. 1 completed a straight-forward 6-4, 6-1 win, despite being broken twice in the first set.
"It`s never easy playing someone from your own country, especially someone you don`t know," said Ivanovic.
"I really knew very little about her. She`s a very good player. She played some great tennis at times today and I really hope she can develop and get to the top of the game."
In the semifinal, Ivanovic will meet her top seed Stosur, who in the second round eased past another qualifier Valeria Solovieva, ranked 216 in the world.
Stosur earlier strolled past Klara Zakopalova of the Czech Republic 6-1, 6-3.
