There was glory for Longniddry's Shona Whillans as she claimed her most impressive national badminton title yet in Motherwell on Sunday.

Whillans partnered Edinburgh's Gemma Wright in the girls' doubles and the two lived up to their billing as the top seeds to take the title at the Under-15 Scottish National Junior Badminton Championships at Ravenscraig.

The success was all the more impressive as Whillans had only recently stepped up to the under-15 age group after sweeping the field to claim three trophies in last year's under-13 competition.

The Preston Lodge pupil and her partner were all-conquering in winning the tournament, not dropping a single game along the way.

They were given a bye into the quarter-finals on the basis of their top seeding and then dispatched Sarah Sidebottom and Annabel Young 21-9, 21-15.

The semi-finals pitted Whillans against fellow Longniddry girls Sarah Brogan and Eloise Morris, who had made it to the last four courtesy of impressive straight-game victories over first Biatrice Gabell and Alyx Middleton, then another Longniddry girl in Laura Moos and her partner Linsey Young.

But Whillans and Wright proved too strong, triumphing 21-11, 21-11 to make it to the final.

Facing them there were the No 2 seeds Cara McCulloch and Eleanor O'Donnell, who gave Whillans and Wright a run for their money, but it was the Longniddry teen and her partner who triumphed 21-19, 21-19, dominating the longer rallies on their way to lifting the title.

But this time there was to be no treble success for Whillans, although she did enjoy good runs in both the mixed doubles and the girls' singles.

Partnering Edinburgh's Glen Lewington in the mixed doubles, Whillans picked up a first-round win over her girls' doubles partner Wright and Matthew Duguid 21-18, 21-18, then defeated Calum Atterbury and Lily Farnood 21-17, 21-16 to reach the semi-finals.

But there top seeds Alex Dunn and Holly Newall proved too strong, winning 21-14, 21-18 and going on to take the title, with Dunn managing a title treble himself.

Sarah Brogan and partner James Laing lost in the quarter-finals.

In the girls' singles, Whillans opened with a 21-9, 21-13 win over Olivia Quinn, then a simple 21-9, 21-9 triumph over Sophie Law, but Cara McCulloch proved too strong in the quarter-final, taking the first game 21-9, then edging the second 22-20 despite a great effort from Whillans.

Elsewhere there was an all-Longniddry first-round clash as Eloise Morris met Basia Grodynska, North Berwick High School pupil Grodynska winning 21-17, 17-21, 21-16 in an exciting match but then going out in the second round.

Sarah Brogan also suffered second-round defeat, while Laura Moos lost in the first round.

Meanwhile, flying the county flag for the boys was North Berwick's Cameron Law, fresh from claiming his maiden national singles title with victory in the Under-15 Scottish Schools Age Group Singles earlier this month.

The North Berwick High School pupil had defeated Edinburgh's Craig Ferguson in the final of that event, while Grodynska and Morris had finished second and third respectively in the girls' competition.

This weekend, Law also looked impressive, thrashing Euan Kennedy 21-3, 21-8 in his first match after a bye, then reaching the quarter-finals after a 21-12, 21-13 win over Andrew Robertson.

However, Law would come out on the wrong side of a tight three-game fixture against Scott Waddell, going down 21-12, 19-21, 21-14.

Preston Lodge pupil Douglas Crawford, third in the competition that Law had won, lost in the first round this time out.

Meanwhile, in the under-19 tournament played at the same time, Haddington's Hannah Laing was defending the doubles title she won last year with fellow Haddington player Megan Richardson, who was unable to take part this year because of injury.

Now partnering Caitlin Gilmour, Laing reached the semi-finals with a 21-12, 21-14 victory over Sarah Allan and Emma Wengel, but she and Gilmour missed out on a place in the final after going down 21-19, 21-15 to second seeds Heather and Julie MacPherson.

Tranent's Kelly Sands and partner Hannah Wade lost in the first round, as did Sands in the girls' singles, but she and partner Tommy Reynolds won their first match in the mixed doubles before a narrow quarter-final defeat.
