Hannah Miley claimed her second medal of the World Short-Course Championships when she was third in the 200 metres individual medley in Istanbul.

The 23-year-old struck gold in her specialist 400m event on the first night of competition, breaking her own European record in the process, but last night, the Garioch swimmer was fourth with 50m to go before managing to touch in 2:07.12 to force her way on to the podium. China's Shi Wen Ye won the gold in 2:04.64, just 0.04 outside the world record.

Miley, seventh in this event at the Olympics, said: "I am really, really happy with that. It has given me another boost of confidence and motivation for the next part of the season.

"That was probably going to be one of the hardest races here – I thought maybe I'd be fourth at the best, maybe fifth or sixth. I'm a little bit gutted with the time. I was hoping to do the same time I did at the Euros because that felt absolutely amazing. But I can't knock getting a sneaky bronze. It's better than nothing."

The lights went out during the breaststroke leg to plunge the Sinan Erdem Dome into semi-darkness but the Garioch swimmer was not distracted.

Ye's freestyle speed sparked much questioning at the Olympics but for her rivals it means they have to find a response. Miley added: "I've been trying to work on my backend speed. Ye Shiwen can do it so it's something we've been trying to strive for to show it's possible to come back really, really strong. Those girls go out so hard and it's a matter of hanging on for dear life and that's what I did. My little arms and legs were working so hard on that last 50."

At the Scottish Gas National Open Short Course Champ-ionships at the Royal Commonwealth Pool in Edinburgh, Charlotte McKenzie – one of Scotland's brightest young prospects – completed an impressive backstroke double. Winner of the 50m with a Scottish record on Friday, the 16-year-old added the 200m with a Scottish junior record of 2:10.43 as she snatched the title just ahead of another 16-year-old, Dundee's Kirsty Simpson (2.10.70).

"I'm very happy with the time and I've got the 100m tomorrow," said the Larbert High pupil, who is coached by Steven Tigg. "This is a good end to the year. My goal for 2013 is to get to the World Junior Championships and then there are the Glasgow Commonwealth Games in 2014."

World Open-Water Champion Keri-anne Payne claimed her second title of the Championships and showed her fierce competitive spirit. Despite having trained "not a lot" since moving to Edinburgh after her marriage to Scottish swimmer David Carry, the new Warrender recruit touched in 4:10.89 in the 400m freestyle and finished ahead of Sheffield's Sian Morgan (4:11.34).

"It's good to get back in the water," said Payne, who had already got the 800m title on Friday, adding: "It's been great competing for a first time at the Commonwealth Pool."

Edinburgh University's Kathryn Johnstone won the 100m breaststroke on the opening night and the 2010 Commonwealth Games swimmer duly added her favourite 50m title in 30.90, while Lewis Smith, who swam for GB in the 2010 World Championships, confirmed his hunger still exists. The Warrender 24-year-old suffered a blow when he missed the London Olympics, but a winning 1:59.21 in the 200m butterfly confirmed he remains on course for a second Commonwealth Games in 2014.

Emily Jones, who recently switched clubs from Garioch to Aberdeen, claimed her first senior Scottish title in the 100m butterfly. The 17-year-old touched in 1:01.00. Fiona Donnelly was second in 1:04.19.

With the 100m gold already in the bag, Edinburgh University's Sarah Eaglesham completed the freestyle sprint double, taking the 50m crown in 25.68.
