Jelena Jankovic’s bad results are becoming worrying. We know she’s struggling to bring her form back, but this latest second-round loss at the BNP Paribas Open is only deepening the despair.

The second-seeded Jankovic was upset by young Anastasia Pavlyuchenkova 6-4 6-4. The 17-year-old Pavlyuchenkova, ranked 42th in the world, scored her first Top 10 victory.

"Last year I finished No.1 in the world and I was playing great tennis, especially at the end of the year. This year I'm not the same player," Jankovic said. "I'm struggling to find my game and the confidence on the court. She played well. Obviously she was the better player. But I'm not at my level."

Third seed Elena Dementieva was also stunned, but her loss is much less worrying than Jankovic’s. Dementieva has won two WTA titles this year and overall has been amazing in 2009, so we can understand her tiredness.

Dementieva was erratic and hit 14 double faults before falling to qualifier Petra Cetkovska 7-6(2) 2-6 6-1 in the second round of Indian Wells.

"That was probably my worst match in a long time," Dementieva said. "Every time you lose you're trying to learn something. I feel I shouldn't have come here because I played a lot of matches at the beginning of the year, and I probably needed more time off to recover."

Ana Ivanovic didn’t suffer the same faith as Jankovic and Dementieva. After losing the first three games of the match, the fifth seed won 12 of the next 16 games and beat Belarusian qualifier Anastasiya Yakimova, 6-4 6-3. (source: Sony Ericsson WTA Tour, photo: Ralf Reinecke)

Sixth seed Svetlana Kuznetsova, who has reached the final at Indian Wells for the last two years, fell in the second round to wildcard Urszula Radwanska. Top seed Dinara Safina survived a tough test before beating Tsvetana Pironkova.

Kuznetsova was overpowered by the world No.107 Radwanska 6-2 4-6 6-3, despite a comeback in the second set.

Safina saved multiple set points in the first-set tiebreak before easing through the second set and beating the Bulgarian world No.50 7-6(8) 6-2. Safina will meet seed No.28 Shuai Peng of China in the third round of the BNP Paribas Open.

Safina, ranked 2nd in the world, can replace Serena Williams atop the WTA Tour rankings by reaching the Indian Wells final, as Williams is not playing the tournament. (sources: ESPN, Reuters, photo by our reader Jacob)

Maria Sharapova played her first competitive match since last August, paired with Elena Vesnina at the BNP Paribas Open. The Russians lost to Ekaterina Makarova and Tatiana Poutchek 6-1 4-6 10-7 in the first round.

Despite the defeat, Sharapova is glad to be back:

It feels pretty good, it's pretty amazing. I came here and just wanted to test it out. I started training a couple of months ago and I thought I'd test it out in a match situation and play in front of a crowd, and it was exciting.

The disappointing fact is that Sharapova is still not ready for high-intensity competition:

I think the hump I've got to get through right now is to put two weeks of playing two, three sets every single day, for two weeks and feeling great, 100 percent. Right now I am able to do maybe three days, four days and then I have to take it easy on the fifth. Obviously that's not the way to go about a tournament in singles, so that's what I am working up to right now and whenever that comes, that's when I'll be playing singles.

The 21-year-old Sharapova hadn’t played doubles since mid-2005, but chose to make her return to tennis after a seven-month absence slowly, and hence opted for avoiding singles at the beginning. (source: ESPN, photo: Ralf Reinecke)

Jelena Dokic couldn’t repeat her Australian Open heroics, losing in the first round of the BNP Paribas Open in Indian Wells.

The 2009 Australian Open quarterfinalist, who has risen from No.178 to No.80 in the rankings this year, lost in straight sets to 34-year-old American Jill Craybas 6-4 6-2.

Dokic said she may have been mentally beaten before taking the court against Craybas. The Australian also said: "I'm really, really struggling mentally. I need to just settle down and get myself together again."

In her only other outing since Melbourne, the 25-year-old Dokic was defeated in the opening round of Memphis by top seed Caroline Wozniacki. (source: ESPN, photo: Ralf Reinecke)

Now it’s official: Maria Sharapova will start her return from shoulder injury by playing doubles at the BNP Paribas Open at Indian Wells.

Besides confirming that she’s playing doubles at the next week’s tournament, Sharapova commented on the recovery process on her official website:

I am excited to be playing competitive tennis again. The healing process takes time, and requires things to move more slowly than I would like, but I am taking things one step at a time. I look forward to playing at the BNP Paribas Open, it is definitely one of my favorite tournaments in the world. (photo: Ralf Reinecke)
