England's Sarah Walker is expecting a "much tougher match" in this evening's quarter-final meeting with Sri Lanka.
Walker, along with mixed doubles partner Rajiv Ouseph, picked up a third successive victory at the Commonwealth Games courtesy of a 5-0 triumph over Mauritius at the Emirates Arena.
The British number two, who saw off former teammate Elizabeth Cann 21-15 21-13 yesterday in the women's singles at the Emirates Arena, said: "I was just trying to build on yesterday's performance and keep it going.
"The quarter-finals will be a much tougher match and I think we are all prepared for it. If we carry on playing how we are then I think we can win."
Walker won the English National Badminton Championships earlier this year.
