INDIAN WELLS, Calif. (AP) – Fourth-seeded Andy Murray advanced to the third round of the BNP Paribas Open with 7-5, 6-3 victory over Spain’s Albert Montanes on Saturday.

Murray fell behind, 3-1 and 4-2, in the first set but won the final two games and the final three of the match to advance to a matchup with Paul-Henri Mathieu of France.

“I wanted to just give it 110 percent,” Murray said. “I saw that I wasn’t going to play my best tennis and it would be dumb to think like that. I thought I moved great, the best I had moved in quite a while. I wasn’t hitting the ball particularly well, but I moved well.”

Elena Dementieva, the women’s No. 3 seed, did not fare as well, losing to 24-year-old Czech qualifier Petra Cetkovska, 7-6 (2), 2-6, 6-1, in their second-round match.

Fifth-seeded Ana Ivanovic of Serbia opened defense of her title with a 6-4, 6-3 victory over Anastasiya Yakimova of Belarus. Also, No. 7 seed Agnieszka Radwanska of Poland beat Samantha Stosur of Australia, 3-6, 6-3, 7-5, to join younger sister Urszula Radwanska in the third round.

Jo-Wilfried Tsonga of France, the 11th seed, beat Teimuraz Gabashvili of Russia, 7-5, 6-3.

Dementieva, who was playing in her seventh event of the year, said she will take a couple of much-needed days off and then get ready for the next tournament, at Miami.

“I just feel like I probably shouldn’t (have) come here because … I just needed to take some time off and get ready and recover. I just needed a much longer break to get ready to play at my best,” she said. “It was a very short period of time (off) after Dubai. When it was time to start practice again I was just too tired. That probably was the worst match for a long time for me.”

It was the best match ever for Cetkovska, a pro since 2000 with a career-best ranking of No. 49 last June. She had a win over then-No. 11 Marion Bartoli last year, but said she didn’t expect to beat Dementieva.

“The key I think is that I was still playing and still trying to believe that I can do it and to play every point and we’ll see what will happen,” said Cetkovska, who lives in Paris. “I think there was something that I should try not to do, to let her be aggressive on me. So every single opportunity I had, even if I could make a mistake, it was to try to be aggressive before her.”
