New Delhi, April 9 -- Young debutant Vaishnavi Adkar bounced back in style, registering a 6-2, 6-4 win over Aishi Das in the opening singles to give India a 1-0 lead against New Zealand in their second Asia/Oceania Group I tie of the Billie Jean King Cup here on Wednesday. Vaishnavi had endured a disappointing start to her campaign on Tuesday as India went down 1-2 to Thailand in a rain-hit opener. Entrusted with the responsibility again, the youngster showed marked improvement, cutting down on unforced errors and executing her shots with far greater control to outplay Das in an hour and 30 minutes. "It was my first match playing in the Billie Jean King Cup, so I was definitely very nervous. I did not handle my nerves well. But that was a lesson learned for me," Vaishnavi said. "Coming on court today, I had to focus on what I do best. And all I had to do was go to court and give my best." Vaishnavi dominated the key moments, capitalising on Das' inconsistency to take control of the opening set. Despite trailing 15-40 early on serve, the Indian earned the first break as Das squandered a 40-15 lead with a string of errors. She then held through a tight deuce battle to move 2-0 ahead. Vaishnavi showed resilience under pressure in the third game, saving two break points, and maintained her advantage as both players held serve to 3-1.The Indian struck again in the fifth game, converting her second break point to extend the lead....
