Former champion Maria Sharapova overcame Spain's Carla Suarez Navarro to reach the fourth round of the BNP Paribas Open on Sunday.
The world number three, seeded second at Indian Wells, won four of 10 break points on her way to a 7-5 6-3 victory in one hour and 18 minutes.
Suarez Navarro led 5-4 in the first set and 3-2 in the second, but failed to hold on as Sharapova, who won the tournament in 2006, upped the ante.
"I thought it was a tough one. She's a quality player, capable of playing some really good tennis," Sharapova said.
"There are a few things I want to improve on, but I was happy I got through on not a great day."
Meanwhile, Spain's Lara Arruabarrena-Vecino claimed the most notable win of her career after beating Italian 14th seed Roberta Vinci 2-6 6-4 6-4.
Arruabarrena-Vecino, who ousted American 22nd seed Varvara Lepchenko in the previous round, won three of five break points to prevail in one hour and 44 minutes.
In other matches, Polish third seed Agnieszka Radwanska proved too strong for Romania's 27th seed Sorana Cirstea, winning 6-7 (3-7) 6-3 6-4.
French ninth seed Marion Bartoli won six of 11 break points in a comfortable 6-4 6-3 victory over Russia's Svetlana Kuznetsova.
