Shahar Peer returned to action Friday after a two-week absence with a 6-3 6-0 win over China's Sun Tiantian in the second round of the Pacific Life Open at Indian Wells.
The 11th seed, who received a bye to the second round, looked rusty at the start as she allowed Tiantian to lead 3-1 in the first set, but came back to win the next 11 games and book a third round clash with Czech teenager Lucie Sarafova.
The 19th seeded Sarafova survived a third-set tie-break in a 6-3, 6-7, 7-6 win over Poland's Agnieszka Radwanska.
Peer was scheduled to play overnight with Vania King in the first round of the women's doubles.
Former champion Martina Hingis cruised, but top-seed Maria Sharapova had to work a little harder to secure opening victories in the event.
Hingis booked her place in the third round with a 6-1 6-3 trouncing of Denmark's Caroline Wozniacki, while Sharapova rattled up 10 double-faults before beating Dutch player Michaella Krajicek 7-6, 6-4.
Tournament winner in 1998 and twice a runner-up at the Indian Wells Tennis Garden, Hingis broke her opponent three times in the opening set before clinching victory in less than an hour.
The world number 6, who claimed her 43rd WTA Tour singles title at last month's Pan Pacific Open in Tokyo, is determined to retain her top-10 ranking by the end of the year.
Sharapova, competing for the first time since being forced to retire with a hamstring injury midway through her Pan Pacific Open semifinal against Serbia's Ana Ivanovic in Tokyo last month, looked particularly rusty in the first set.
"I've been out of competition for the last five weeks and I didn't know what to expect," said the 19-year-old U.S. Open champion, who crushed fellow Russian Elena Dementieva 6-1, 6-2 in last year's final.
Seventh seed Jelena Jankovic of Serbia brushed aside American Shenay Perry 6-1 6-3, and Slovakia's Daniela Hantuchova, the 2002 champion at Indian Wells and seeded 14th this year, was given a tougher workout before beating Estonia's Kaia Kanepi 6-2 2-6 6-1.
