Jemma Lowe claimed her second medal of the World Short-Course Championships as she finished third in the 100 metres butterfly in Istanbul.
The 22-year-old had won the first British medal in Turkey when she took bronze in the 200m event on the opening night of competition.
The Swansea ITC swimmer had qualified third for the two-length event and was second at the halfway point. In a close finish the Briton touched for third in 56.66 seconds, a new Welsh record.
It was Great Britain's fifth medal of the meet at the Sinan Erdem Dome.
Lowe said: "I am over the moon with that result. We have only just started speed work in training - for one week - so I wasn't sure how my speed was going to be.
"I just gave it my best tonight because I knew it was going to be a real fight and I wasn't sure whether I was going to touch and get bronze but I did in the end and I am so happy."
Looking towards next year's World Championships and translating her success to a 50m pool, Lowe said: "I haven't rested much for this and I am really positive about how I am doing now so I am just going to get back in training and keep doing what I am doing.
"Just keep thinking positive and enjoying myself and in the next year get good results, so I am looking forward to it."
Fran Halsall then picked up her first medal of the meet as she finished second in the 50m freestyle.
The 22-year-old Loughborough ITC swimmer had qualified fourth and was in the mix from the start before she finished in 23.87.
Halsall said: "It's good. It's a nice feeling to get a medal again.
"So after a tough summer it's good to come here and get a medal - it is definitely a step in the right direction."
