Three seeded players bit the dust while Prerna Bhambri (in pic) was the lone Indian to win her singles match of the day at USD 25,000 NECC-ITF women's event on Tuesday.
Thai girls Nungnadda Wanasuk, Peangtarn Plipuech and Miyabi Inoue of Japan accounted for the seeds to make it to the singles second round of the event at Deccan Gymkhana here.
Wanasuk comfortably outplayed 5th-seeded local girl Ankita Raina 6-2, 6-3. Wanasuk, with heavy ground strokes from both flanks, broke Raina in the 5th and 7th games of the first set. She broke the Indian three times in the second set to win the contest in one hour and 22 minutes.
Wanasuk now meets the Indian wild-card Snehadevi Reddy for a place in the quarter-finals.
Inoue came back from a one set deficit to edge out 7th seeded British girl Jade Windley 4-6, 6-4, 6-4.
In the third upset, Plipuech played solid tennis to knock out eighth seed Denis Khazaniuk of Israel 6-4, 7-5 in a match that could have gone either way.
Bhambri justified her wild card entry in the tournament by beating Britain's Emily Webley-Smith 6-2, 6-3 in just 61 minutes. The Delhi player broke the British girl in the fourth and eighth games of the first set to win it easily.
Webley-Smith couldn't handle the pressure while serving to stay in the match in the eighth game of the second set, as the Indian girl got the break to enter the last 16.
