Three to See: Women's Draw, Day 6
For single-digit seeds Simona Halep, Agnieszka Radwanska and Garbine Muguruza, the real test of their Roland-Garros credentials starts now.
Simona Halep  v Naomi Osaka
Suzanne-Lenglen Court, First Match
No. 6 seed Halep was made to work in her second-round match against Zarina Diyas, and will be looking to make a good start against an opponent six years her junior. The Romanian arrived in Paris in good form, having come off a win in Madrid earlier this month, and is determined to go one step further than her 2014 final appearance.
Osaka, one of the youngest players in the draw, has already made her mark on the WTA tour, qualifying and making the third round at the Australian Open this year. The 18-year-old has notched up some big wins, defeating the likes of Elina Svitolina and Sara Errani, and like Halep is yet to drop a set thus far in Paris. The world No.101, who is making her first appearance at Roland-Garros, has nothing to lose and everything to gain.
Agnieszka Radwanska  v Barbora Strycova
Suzanne-Lenglen Court, Third Match
Making her 10th appearance at Roland Garros, Radwanska looks in fine form having only lost eight games en route to the third round. The petite, elegant Pole has never lost a set to Strycova in four previous meetings with the Czech, their last back in 2014. Strycova has never gone beyond the second round at Roland-Garros, but has enjoyed an impressive 2016 thus far. She reached the fourth round at the Australian Open and Indian Wells, made the finals in Dubai, and made the quarter-finals in Rome. With both players in form and playing similar games based on touch and angles, this match might just go the distance.
Garbine Muguruza  v Yanina Wickmayer
Philippe-Chatrier Court, First Match
Prepare for a battle between two real power-players of the game. These players have met only once before, back in 2014, when Muguruza advanced courtesy of a Wickmayer retirement. The Belgian has struggled in recent times, and did not win a match on clay in four straight tournaments leading up to Roland-Garros, but has managed to find form at just at the right time. She will look to reach the fourth round at Roland Garros for the first time in her career.
Muguruza, twice a quarter-finalist at Roland-Garros, made a slow start in her first-round match on Monday, but took care of business in the second round, dropping just two games against Myrtille Georges. The world No.4, a firm crowd favourite, loves playing at Roland-Garros and has to be considered a contender for this year's title.
