Marketa Vondrousova takes a 1-0 head-to-head lead into her match with Simona Halep. The 19-year-old Czech upset Halep in the round of 16 at the BNP Paribas Open in Indian Wells earlier this season. That was the first of Vondrousova's back-to-back quarterfinal showings at Indian Wells and the Miami Open this year.

Halep is seeking her first Rome title, after falling to Elina Svitolina in the final in the last two years. She was also a semifinalist in 2013 and 2015 and holds a 15-6 career win-loss record at the event overall.
