Former Wimbledon champion Petra Kvitova survived a scare against Olga Govortsova in their second-round match at the BNP Paribas Open.
Kvitova was taken to a deciding third set by the world number 67 at Indian Wells before recording a 6-4 3-6 6-3 victory to set up a third-round clash with Ukrainian qualifier Lesia Tsurenko.
Fifth seed Kvitova will be taking on a player who claimed a seeded victim today, knocking out Kazakhstan's Yaroslava Shvedova.
The 31st-seeded Shvedova was strong in the middle of the match but weak at both ends as she crashed out 6-1 3-6 6-1.
Italian 14th seed Roberta Vinci accounted for another Kazakh player, beating Ksenia Pervak 6-3 6-4, while Swede Johanna Larsson ousted Russian 26th seed Anastasia Pavlyuchenkova by a 7-5 6-1 margin.
With the men's event a round behind, there were no seeded players in action today.
Among the day's early first-round winners were Spaniards Pablo Andujar and Albert Ramos, Australian qualifier Matthew Edben and his compatriot Marinko Matosevic, German qualifier Philipp Petzschner and Russian Evgeny Donskoy.
