Garbine Muguruza staved off elimination at the WTA Finals after the former world number one rallied past Barbora Krejcikova 2-6 6-3 6-4.
Having both lost their opening matches at the year-ending championship, sixth seed Muguruza and second seed Krejcikova went head-to-head in a crucial showdown in Guadalajara.
Muguruza dropped the opening set on Friday but completed a spirited comeback to stay alive in Mexico, where the two-time grand slam champion rallied from a set down to beat a top-three opponent for the first time since her triumphant Wimbledon campaign in 2017.
Spanish star Muguruza is still in the mix to progress to the semi-finals as she improved to 1-1 in Group Teohuatican, while Krejcikova dropped to 0-2.
French Open champion Krejcikova – who would have eliminated Muguruza with victory – raced through the opening set in 36 minutes, having converted all three of her break-point chances.
Muguruza, though, bounced back to claim a 4-1 lead and while Krejcikova battled, the former fired down five aces and hit 10 winners to level the match.
After exchanging holds, a monumental 12-minute game saw Muguruza – who would have ousted her opponent with a straight-set victory – break at the sixth time of asking and she maintained that momentum to close out the tense contest.
Krejcikova – 26/33
