Kristina Mladenovic's results at her home Slam have been an arc of gradual progress. She lost in the first round in her first four outings, as a wildcard from 2009-12; won her first match in 2013, her first year of direct entry; and for the past three years has made the third round. Today, she'll be looking to make the second week for the first time.
Ons Jabeur, who lost to Miyu Kato in the last round of qualifying before getting a second chance in the main draw with Laura Siegemund's withdrawal, is the first Lucky Loser to play the third round at Roland Garros since Gloria Pizzichini in 1996. The last - and only - Lucky Loser to make the fourth round here was Nicole Jagerman in 1988.
Today marks the third time Lesia Tsurenko and Jelena Ostapenko have played each other this year. The Ukrainian triumphed 6-3, 7-6(5) in the Acapulco quarterfinals, but the Latvian got her revenge on clay, 6-4, 6-3 in the first round of Prague.
Four players in action today have won WTA Tour trophies in 2017. Kristina Mladenovic is the only woman to have won a Premier title, in St Petersburg; the others are Elise Mertens (Hobart), Lesia Tsurenko (Acapulco) and Samantha Stosur (Strasbourg). Mladenovic has reached three further finals (Acapulco, Stüttgart and Madrid); Mertens also notched up a runner-up plate in Istanbul.
No.23 seed Samantha Stosur has not faced Bethanie Mattek-Sands, her opponent today, in eight years. The Australian won their only senior meeting 6-4, 6-7(6), 6-2 in the first round of Wimbledon in 2009 - but they also played three times as juniors between 2000-01, with the American winning twice.
In her 20th Roland Garros, Venus Williams is bidding to make the second week for the tenth time today. By contrast, her opponent Elise Mertens is playing her first Roland Garros - and this is the first time she's won a match at any Slam.
No.32 seed Zhang Shuai snapped a six-match losing streak with her first-round win over Donna Vekic - and has won two consecutive matches for just the second time this year for a career-best showing at Roland Garros. She trails her opponent today, No.8 seed Svetlana Kuznetsova, 1-4 in the head-to-head - but won their most recent meeting, in Prague in 2015.
Caroline Wozniacki's 6-0, 6-0 win over qualifier Françoise Abanda in the second round was the fourth of her career. Previously, she had dished out double bagels to Edina Gallovits (New Haven 2009), Chang Kai-Chen (US Open 2010) and Belinda Bencic (Istanbul 2014).
Five of last year's quarterfinalists are in action today, including two - Yulia Putintseva and Shelby Rogers - who reached that stage as unseeded players.
