Bae YJ has been playing more forcefully in the Games here, not rallying too much as usually characteristic of her play and it's paying dividends - she just ousted Intanon R by the score of 21-4, 18-21 and 21-8 !
I think Wang YH will have a tough match with her tomorrow as Bae YJ also possesses a strong,stubborn defence. WYH had better play more intelligently and not rely overly on brute force or she would be drawn into a bruising, exhausting battle.
