Britain's Katie Boulter progressed to the last 16 of the Lyon Open after fighting back to beat Ana Konjuh.
The 25-year-old fought back to knock out sixth seed Konjuh of Croatia 5-7 6-0 6-3.
Boulter had breezed through qualifying to secure her place in the main draw and will next face Hungary's Anna Bondar.
Fellow Briton Heather Watson won her first-round match at the Monterrey Open, beating Germany's Jule Niemeier.
Watson, ranked 107th in the world, won 6-3 2-6 7-6 (7-4) and will attempt to earn back-to-back matches in a WTA main draw for the first time this year when she faces Spanish sixth seed Nuria Parrizas Diaz or Japan's Misaki Doi.
Ukrainian Elina Svitolina is scheduled to face Russian Anastasia Potapova at the tournament.
However, following Russia's invasion of Ukraine, top seed Svitolina has said she will refuse to play Russian or Belarusian players until they are classed as 'neutral athletes'.
The WTA has still not commented publicly on Svitolina's demands.
Potapova says she never takes an opponent's nationality into account and that professionals are now becoming "hostages of the current situation".
