Beatriz Haddad Maia and Madison Keys have both progressed to the quarter-finals of the Internationaux de Strasbourg.

American Keys, seeded fourth, surged clear of China’s Wang Xinyu in a dominant second set to prevail 7-5 6-0, only being broken once in the match.

Haddad Maia, meanwhile, fought back from losing the first three games to defeat Emma Navarro 6-4 7-6 (7-1) in a keenly contested battle.

Top seed Marketa Vondrousova and two-time tournament winner Elina Svitolina are among the other players due to play later on Wednesday.
