Quigley breaks English record
Lauren Quigley broke the English record in the 50m backstroke to clinch her second gold medal in the British Gas Swimming Championships.
The 19-year-old touched home in 27.90 seconds - 0.09 ahead of British record holder Georgia Davies - while Fran Halsall set a personal best of 28.04 to add a second bronze medal to her three golds in the final session of the six-day event.
Quigley earlier won the 200m and finished second behind Davies in the 100m and she hopes her impressive performances are enough to clinch a place in the England team for the Commonwealth Games in the same Tollcross pool.
The Stockport Metro swimmer said: "I've wanted to break the 28 mark for quite a while so to do that here is great.
"I felt good in the race and I had Fran and Georgia either side which was great, as they are always good to race.
"It's a massive confidence boost. I'll see if I make the team when it's announced and if I do I will try to race faster here in the summer."
Roberto Pavoni completed a hat-trick of golds with victory in the 200m individual medley, but his time of 1:59.08 minutes was outside the English Commonwealth Games nomination time.
The Loughborough-based swimmer previously won the 400m event and the 200m butterfly, and he hopes to compete in all three when he returns to Glasgow in July.
The 23-year-old said: "Because I went under the qualifying time on the 400 IM, I hope I'll be allowed to swim all three.
"I'd really like to, they are always part of my training programme, and with the 400 IM you have to train on all the strokes anyway."
Pavoni, who finished ahead of Joe Roebuck and Lewis Coleman, added: "It's been tough. I found it difficult to back up 400 IM and 200 fly straight after each other but that's what everyone has to do this year.
"I'm happy with my three golds, happy with my 400 IM, slightly disappointed with my other two times, but all in all I'm pretty happy and it puts me in good stead for Glasgow in a few months."
British record holder Adam Brown won his third consecutive 50m freestyle title with a time of 22.27 seconds, pipping Ben Proud as he did in the 100m, with Scot Richard Schafers winning bronze.
Jazz Carlin followed up her victory in the 800m freestyle 24 hours earlier with a dominant victory in the 400m.
The Welsh swimmer, who has qualified for three events for the Commonwealth Games, retained her title with a race of 4:04.68 minutes. Aimee Willmott recorded a personal best of 4:08.98 in silver and Ellie Faulkner took bronze ahead of Scot Hannah Miley.
England's Daniel Fogg recorded his third sub-15 minute race in the 1500m freestyle to finish in 14:59.86, almost 12 seconds ahead of runner-up Jay Lelliott, but he is left to sweat on his Commonwealth Games place.
The Loughborough University swimmer said: "I'm a little bit disappointed with my time because I thought I could get a PB and I'm three seconds off the qualifying time, but we'll just have to wait and see."
There is no such wait for 17-year-old Swansea University swimmer Daniel Jervis, who knocked 29 seconds off his personal best in the junior 1500m freestyle to beat the Welsh Commonwealth Games standard time with a race of 15:16.46.
