Rising Russian star Mirra Andreeva became the first 17-year-old player to reach the women's final at Indian Wells since 2001 after overcoming defending champion Iga Swiatek in the last four.
She beat the world number two for the second time in as many tournaments, after knocking her out at the quarter-final stage in Dubai in February on her way to becoming the youngest winner of a WTA 1000 tournament.
Andreeva extended her winning streak to 11 matches as she bounced back from losing a one-sided second set to beat the experienced Pole 7-6 (7-1) 1-6 6-3.
