ATP Doha : Nadal vs Santoro Live Streaming Online

Now playing under the name Date-Krumm, she succumbed 6-4 6-3 to American Jill Craybas in her first WTA tournament outside Japan in 13 years.

The 38-year-old Japanese player, who unexpectedly came out of retirement last year, looked dazed at the start and promptly lost the first four games against Craybas.

She fought back to trail 5-4 in the first set but paid the price for holding serve only once in the second.

"My opponent wasn't the type who tries to overpower you but she played a smart game," Date-Krumm said. "I was in shape to play but practice is different from an actual game."

Seeds Anabel Medina Garrigues, Aleksandra Wozniak, Shahar Peer and Nicole Vaidisova all enjoyed a good start to their 2009 seasons.

Third seed Medina Garrigues of Spain overcame a tricky start to overpower Italy's Mara Santangelo 7-5 6-0.

Fourth seeded Canadian Wozniak defeated Magdalena Rybarikova of Slovakia 6-3 6-7 7-5, number five Peer beat Petra Cetkovska 7-6 6-2 and former Australian Open semi-finalist Vaidisova squeezed past Russia's Alla Kudryavtseva 7-6 4-6 7-5.
