Two former French Open champions meet for a spot in the semifinals when third-seeded Garbine Muguruza takes on Maria Sharapova. Muguruza won her first major title two years ago in Paris by defeating Serena Williams in the final while Sharapova is a two-time Roland Garros champion. Still chasing a maiden major trophy, top-ranked Simona Halep takes on 12th-seeded Angelique Kerber. In men’s play, 10-time champion Rafael Nadal faces 11th-seeded Diego Schwartzman and No. 3 Marin Cilic is up against No. 5 Juan Martin del Potro in a matchup between two former U.S. Open champions.
