No slips from Jamieson
Michael Jamieson safely negotiated the heats of the 200 metres breaststroke at the British Gas International Swim Meet 2013 in Leeds.
Also on Saturday morning Jaz Carlin won her second title of the meet at the John Charles Centre for Sport when she dominated the one-off 1,500m freestyle.
Jamieson had to come through a swim-off to make the 100m breaststroke final on Friday, which he then went on to win.
On Saturday the Glasgow-born swimmer was fourth fastest in two minutes 14.76 seconds with Bath ITC team-mate and Olympic finalist Andrew Willis second through along with Olympian Craig Benson.
The 25-year-old was satisfied with his effort and revealed his intentions to go hard from the outset in Saturday night's final.
He said: "It was all right. These meets are a bit funny, I am not rested for it.
"I've still got heavy legs from training. It's quite hard to get up for the morning swims and try to get yourself going for swimming fast.
"I swam pretty well last night. It was a mid-season PB so I am looking to get another one tonight.
"I'm going to really push it tonight. I'm going to go for it from the start and see how well I can hold on."
Carlin has endured a difficult couple of years, her battles with illness culminating in missing out on the Olympic team.
She won an emotional 800m freestyle on the first night and followed that up with a dominant victory over the longest distance in 16:18.80 ahead of Keri-anne Payne, now based in Edinburgh, and Ellie Faulkner.
The Swansea ITC swimmer said: "It was difficult because I haven't raced it for about six years.
"I would have liked to have gone faster, I think I have got a little bit of a faster time in me."
Taking on the event at this summer's World Championships is a possibility with her coach Bud McAllister keen for her to focus on the distance races.
World 50m backstroke champion Liam Tancock did enough to make the 100m final, his time of 56.56 equal sixth with Chris Walker-Hebborn fastest in 55.07.
Tancock, fifth in London last summer, said: "Yeah, pretty good. It's just about making it through the rounds.
"Everyone is in different states of readiness, fitness. I am in a bit of a racing phase."
Olympic champion Ranomi Kromowidjojo headed a fast 50m freestyle field with Fran Halsall, Emma Wilkins and Amy Smith also progressing.
Jemma Lowe, sixth in London, dominated the heats of the 200m butterfly with Plymouth-based Olympic champion Ruta Meilutyte heading the 100m breaststroke and hot prospect Siobhan-Marie O'Connor also through.
World finalist Roberto Pavoni was third fastest into the 400m individual medley final behind youngsters Max Litchfield and European junior champion Matt Johnson, while Ben Proud headed the 50m butterfly.
In the multi-disability events, Susie Rodgers (S7) won gold in the 50m
butterfly in a one-off race while Matt Walker (S7) led the qualifiers in the
Helen Dolphin (SM4) won 150 individual medley gold with Lyndon Longhorne (SM4) taking the men's title.
Natalie Massey (S14) heads the multi-classification (MC) 200m individual medley with Ellie Simmods in eighth while Sascha Kindred (SM6) leading the men's field.
