Serena Williams advanced past Vitalia Diatchenko in their only prior meeting, when the Russian retired while trailing Williams 6-0, 2-0 in the first round of the 2015 US Open. A win for Williams on Monday would mark the 800th main draw victory of the former World No.1's career, while an upset by Diatchenko would be the Russian's first-ever Top 10 win.
Williams will be making her 17th appearance at Roland Garros in her quest to tie Margaret Court for the all-time Grand Slam record with 24 titles. Williams owns the most titles (three -- 2002, 2013, and 2015) and match wins (63) at Roland Garros among active players. She has reached the finals in three of her last five appearances in Paris, winning in 2013 and 2015, and finishing as runner-up in 2016.
Caroline Wozniacki and Veronika Kudermetova will face off for the first time. Former World No.1 Wozniacki made her Grand Slam main draw debut in Paris in 2007, and since then has compiled a 21-11 record at the event. The Dane's best showings at the event are quarterfinals in 2010 and 2017 -- both of those times, she lost to the eventual champion (Francesca Schiavone and Jelena Ostapenko respectively).
Kiki Bertens comes into Roland Garros at a career-high ranking of No.4, but faces a stern test in her opening round -- her opponent Pauline Parmentier has won all three of their previous encounters, which all came on hardcourt between 2014 and 2016. However, Bertens has 12 match-wins on clay this season, tied for the most on the surface so far this year (Petra Martic and Maria Sakkari also have 12).
Petra Kvitova has a 5-2 head-to-head lead over Sorana Cirstea; this will be their first meeting since Wimbledon 2016. Kvitova is currently tied with her compatriot Karolina Pliskova for most match-wins in 2019 to date (28 apiece).
8th-seeded Ashleigh Barty is enjoying her highest-ever seeding at a Grand Slam event this fortnight. She will face Jessica Pegula in their first meeting. Pegula is bidding for her second career Grand Slam main draw win, to go alongside a first-round win over Alison van Uytvanck at the 2015 US Open.
On Monday, Alizé Cornet will make an appearance in a 50th consecutive Grand Slam main draw. This is the longest streak among active players.
