Paris, France (SportsNetwork.com) - Former champion Ana Ivanovic advanced to the fourth round at the French Open with a 6-0, 6-3 win over Croatian teenager Donna Vekic on Friday.

The seventh-seeded former world No. 1 Ivanovic, the 2008 champ and 2007 runner-up, won the first seven games of the match and finished with only 11 unforced errors. The Serbian star is in the round of 16 at a Grand Slam for the first time since last year's Australian Open.

The 18-year-old Vekic appeared in her first third-round match at a major.

Meanwhile, ninth-seeded Russian Ekaterina Makarova handled fellow countrywoman Elena Vesnina 6-2, 6-4 and 13th-seeded Czech Lucie Safarova tackled 20th- seeded former Wimbledon runner-up Sabine Lisicki of Germany 6-3, 7-6 (7-2).

The quiet Makarova is trying to reach her seventh Grand Slam quarterfinal in her last 14 majors. She appeared in the semis at the last two Slams -- the U.S. and Aussie Opens.

An upset came when 21st-seeded rising Spaniard Garbine Muguruza took out 11th-seeded German Angelique Kerber, 4-6, 6-2, 6-2.

In other third-round play, 19th-seeded Ukrainian Elina Svitolina beat German Annika Beck 6-3, 2-6, 6-4 and 29th-seeded French favorite Alize Cornet rallied for a 4-6, 6-3, 7-5 win over Croatia's Mirjana Lucic-Baroni, who stunned last year's French Open runner-up Simona Halep on Wednesday.

Cornet is into the fourth round at her home major for the first time in 11 attempts.

"At last, I'm into the second week at Roland. I've been waiting for this for 11 years," she said.
