Kirsty Gilmour and Jillie Cooper produced the first big shock of the London Grand Prix today when they knocked out the second seeds Johanna Goliszewski and Birgit Michels.
The unseeded Scottish pair, runners-up at the Czech International last week, won 22-20 21-11 against the pair ranked 21 places above them at No. 21 in the world to book their place in tomorrow night's quarter-finals.
Edinburgh's Cooper said: "I think we found our rhythm with our serving and returns and we executed our game plan brilliantly. I don't think we could have done any better."
The pair will now face the winner of the second-round match between Denmark's Line Damkjaer Kruse and Marie Roepke or England's Sophie Brown and Alyssa Lim.
Gilmour is back in action tonight in the women's singles as she aims to build on last week's successful title defence at the Czech tournament.
Fifth seed Gilmour faces Indonesia's Maria Febe Kusumastuti for a place in the last eight.
