Ace Indian shuttler Saina Nehwal overcame a jittery start to defeat spirited Korean Seung Hee Bae and enter the second round of the All England Badminton Championships here.
The fifth-seeded Indian beat Bae 21-13 21-16 in 34 minutes to set up a clash with Tzu Ying Tai after the Chinese Taipei player beat Bulgaria's Linda Zechiri.
Saina found it hard to adjust to the drift initially, which she said was equally fast on both sides of the court, making it very difficult to play out long rallies.
"When I started the match, I was making a lot of mistakes. I was not really able to adjust to the drift which was on both sides of the court.
