Paris - Former champion Ana Ivanovic reached the French Open fourth round on Friday with a 6-0, 6-3 win over Croatia's Donna Vekic.
Serbian seventh seed Ivanovic, the 2008 champion at Roland Garros, won the first seven games of the match before her 18-year-old opponent got on the board.
Vekic, the world number 165 and playing in the third round of a major for the first time, stopped the rot and broke for 2-1 in the second set.
But that was as good as it got for the teenager as Ivanovic, watched by German football star boyfriend Bastian Schweinsteiger, swept into a fourth round clash against either ninth seed Ekaterina Makarova or Elena Vesnina.
"It's my best match on clay this season," said the Serb who had to come back from losing the opening set in her first two rounds in Paris.
"I don't have a great record on this court (Suzanne Lenglen) so I am trying to correct that."
