Kirsty Gilmour booked her place in the quarter-finals of the Yonex Canada Open in Calgary yesterday with a 21-18 21-17 win over Rachel Honderich.
But there was disappointment for men's doubles pair Martin Campbell and Patrick MacHugh, who went down 21-17 21-18 against Dutchmen Jelle Maas and Robin Tabeling.
That left Gilmour as the only Scot still standing in the tournament. Today she faces the only seeded player left in the women's singles draw when she takes on second seed Aya Ohori.
They have met twice before with the Japanese world No. 18 winning in straight games at last year's German Open while Gilmour, who is No. 45 in the world, won their first meeting at the 2015 Swiss Open.
Ohori is one of four Japanese players through to the last eight after another day of upsets. Four seeds fell in the first round - with Gilmour defeating seventh seed Jang Mi Lee of Korea - and three more fell yesterday.
Against Honderich Gilmour led 12-7 only to find herself trailing 15-13 before finishing the first game stronger. In the second she led 12-8 only to be pegged back to 12-12 before easing away to take victory after 37 minutes.
