Paris, France (SportsNetwork.com) - It took awhile, but former French Open women's champion Ana Ivanovic has again reached the second week of the tournament.

Ivanovic won her lone Grand Slam title back in 2008 at Roland Garros, but hadn't advanced past the fourth round in the six years since winning that championship.

The seventh-seeded Serb waited out a nearly three-hour rain delay on Sunday before earning a 7-5, 3-6, 6-1 triumph over Russian Ekaterina Makarova. She had been knocked out in the fourth round twice, with a pair of third-round losses, a second-round exit and a first-round flameout since beating Dinara Safina for the 2008 crown.

Ivanovic was ahead 3-2 when play was stopped because of the rain. Once play resumed, she broke serve to win the first set. A double fault gave the ninth- seeded Makarova an early break to capture the second before Ivanovic simply dominated the third.

Next up for Ivanovic will be Ukrainian Elina Svitolina, who advanced with a 6-2, 7-6 (11-9) win over French favorite Alize Cornet.

Also slated for women's action later Sunday is reigning champion Maria Sharapova. The second-seeded Russian will take on Lucie Safarova of the Czech Republic.

One other women's fourth-round match will feature Italy's Flavia Pennetta against Spain's Garbine Muguruza.
