BANGALORE, India (AFP) - Unseeded Uzbek Akgul Amanmuradova pulled off a major upset in the WTA Bangalore Open when she beat defending champion Yaroslava Shvedova of Russia in the first round here on Monday.

Amanmuradova was more consistent than the 89th-ranked Russian, winning 6-3, 3-6, 6-3 in 103 minutes.

Shvedova's best came in the second set when she kept pressure on the Uzbek to level the scores but failed to match her rival in the decider, dropping her serve in the sixth game to lose the match.

Hungarian teenager Agnes Szavay, seeded fifth, faced little resistance in her opening match when she defeated wild-card Shikha Uberoi of India 6-1, 6-4.

Sixth-seeded Austrian Sybille Bammer overcame an opening-set deficit to down Japanese Akiko Morigami 2-6, 6-3, 7-5 in another first-round encounter.

"I was not able to adjust initially to the bounce of the court, but came back strongly in the last two sets," said the 20th-ranked Bammer, mother of a six-and-a-half-year-old daughter.

"My daughter used to travel with me on tours in the past and in fact was with me during the Doha Open last month. She is not here, but my mother takes care of her back home."

Bammer trailed 4-2 against the fighting Japanese in the decider, but then played steadily under pressure to win the match.

Japanese Aiko Nakamura also advanced to the second round when she rallied to down Thailand's Tamarine Tanasugarn 6-7 (5/7), 6-1, 6-2.
