Ten wins to three losses saw plenty of Scottish success on day two of the Hungarian Junior International as all doubles pairs progressed in Pecs.
Five doubles pairs were in action in Hungary, with Grimley brothers Christopher and Matthew leading the way as top seeds in the U19 doubles.
The sibling duo, who won their last international tournament in Sweden, took just 19 minutes to beat Czech pair Vit Kulisek and Vaclav Palan 21-9 21-17.
That set up a Saturday quarter-final against Swizz duo Nicolas Mueller and Soen Rimmer, while Christopher also progressed to the singles quarter-finals with two wins in the day.
Grimley beat Austria’s Kilian Meusburger 21-15 21-12 before going on to down team-mate Adam Pringle – who had earlier beaten France’s Rafael Gavois 19-21 21-13 21-9 – with a 21-9 21-8 scoreline.
“I've played Adam quite a few times this season and he is a strong opponent but today I managed to play really well and got a good lead at the start of both sets, which helped me to win in two sets,” Grimley said of his all-Scottish encounter.
“It was a great start in the doubles with our first win of the tournament and hopefully we can continue to win more games on Saturday, which is the start of the quarter-finals.”
The Scottish seventh seed will play Cristian Savin – the Moldovan third seed – in the quarter-finals but he is Scotland’s only singles player left in the tournament after Rachel Sugden lost 21-18 17-21 16-21 to seventh seed Petra Polanc in a 54-minute battle.
The day’s other singles loser was Joshua Apiliga, who went down 21-19 6-21 14-21 to Austria’s Nicolas Rudolf.
But Apiliga did enjoy success in the doubles, partnering Pringle to down Austria’s Luca Froschauer and Simon Ofner 21-15 21-11 before beating Polish third seeds Szymon Stokfisz and Wiktor Trecki 22-20 21-14.
Saturday will see the pair play Czech duo Jan Janostik and Tomas Svejda in the quarter-finals, while he and Sugden will also feature in the last eight of the mixed doubles after beating Jakub Horak and Mia Tarcalova 22-20 21-19 on Friday.
That sets up a clash with Hungarian top seeds Iliyan Stoynov and Hristomira Popovska on Saturday, with a potential all-Scottish final still on the cards after Pringle and Rachel Andrew also reached the quarter-finals.
They beat Mihajlo Tomic and Sara Loncar 19-21 21-10 21-12 on Friday and will play Czech pair Svejda and Katerina Zuzakova in the last eight.
And Andrew will play a second quarter-final on Saturday after she and Rachel Cameron set up a clash with Romanian top seeds Maria Alexandra Dutu and Iona Grecea thanks to two victories on Friday.
They opened their women’s doubles campaign with a 21-13 21-13 win over home duo Bernadett Konya and Boroka Varga before going on to beat Vera Kramarenko and Anastasia Umerenkova 21-12 17-21 21-17.
