Kristina Mladenovic [28] vs. Elena Vesnina [14]
This, it’s safe to say, isn’t the semifinal that tournament officials were hoping to see, and the players in it may not be familiar to many of the people in the crowd at Indian Wells. But the spots have been properly earned. Vesnina, who is ranked near her career-high at No. 15, is coming off wins over Angelique Kerber and Venus Williams. Mladenovic, who has steadily advanced to No. 26 in the rankings and reached the final in Acapulco last week, knocked off Simona Halep and Caroline Wozniacki this week. The 30-year-old Russian is 2-0 against the 23-year-old Frenchwoman, but they haven’t played since 2015. While she’s not ranked as high, Mladenovic has made more progress in that time, and as she continues to get her powerful game under control, seems poised to make a leap into the Top 10 before too long. Reaching an Indian Wells final would be a big step in that direction. Winner: Mladenovic
