Kuala Lumpur: Star shuttler Saina Nehwal sailed into the second round with a convincing win over Belgium's Lianne Tan but World championships bronze-medallist B Sai Praneeth and the seasoned Kidambi Srikanth crashed out of the the Malaysia Masters badminton tournament here on Wednesday.
The London Olymics bronze medallist Saina beat Tan 21-15 21-17 in just 36 minutes of action. This was the first time the two were facing each other.
