The 20-year-old Latvian and the 25-year-old American have never played, but they come in as a well-matched pair. Each made a surprise—no, shocking—run to her first Grand Slam title last year; Ostapenko at the French Open, Stephens at the US Open. Neither had done much in 2018 before this week, but each has found her form again in Miami. Ostapenko has recorded quality wins over Petra Kvitova and Elina Svitolina, and she was all-but-unplayable in straight-setting Danielle Collins in the semifinals. Stephens, meanwhile, has beaten Garbiñe Muguruza, Angelique Kerber, and Victoria Azarenka.
