The 23-year-old defeated Bae 21-11, 17-21,21-13. But this win is no guarantee for the Olympic bronze medallist Saina to make it to the next round.There is a three way tie among Saina Nehwal, Yeon Ju Bae and Mitani for the second place in the group. According to the tournament rules, it will be the difference of games won and games lost that will decide who among the trio will qualify for semifinals as Group B runner-up.
