Jamieson just scrapes through
Olympic silver medallist Michael Jamieson squeezed into the 200 metres breaststroke final at the World Short Course Championships in Istanbul.
The 24-year-old clearly tired in the latter stages of his race and qualified eighth in two minutes 06.05 seconds.
Instead it was team-mate Andrew Willis, eighth at the 2012 Olympics, who stood out with a new English record of 2mins 03.94secs seeing him through to Friday night's final in fourth.
Jamieson could not hide his frustration at missing out on the 100m final and was similarly dissatisfied on Friday.
"I was hopeless this morning. I am just knackered," he said.
"It's hard coming into these events not resting properly and it's more frustrating than anything else.
"I just don't feel I have got much drive coming off those walls and especially in short course little things like that add up - there are seven turns in that race and if I'm losing 30 centimetres on every turn it adds up.
"That is miles off my best time and what I am capable of."
The Glaswegian added: "I have had an amazing year and I am happy to be involved in events like this but obviously I want to be challenging for better positions than I am at the moment."
Lizzie Simmonds - a Bath stablemate of Jamieson and Willis - reached the final of the 200m backstroke, although she too scraped in in eighth in 2:05.65.
Although Simmonds did not claim a medal in London, her fourth place was a bright spot, and an indicator that the 2016 podium is within reach.
Simmonds, who is still adjusting from her post-Olympics move from Loughborough to Bath ITC, said: "It is a big change to the system, I am obviously feeling that.
"It has been a bit of a shock to be changing programme and coaches and changing my lifestyle basically.
"I think that showed a little bit.
"It is to be expected logically - I would like to be swimming really well in there but I am not going away from here being too depressed about it.
"I understand it takes time to settle in and it is a transition period and that is what I am going through."
Senior team debutant Georgia Hohmann was 20th.
The women's medley relay squad of Georgia Davies, Sophie Allen, Jemma Lowe and Fran Halsall have a medal chance tonight having qualified fourth in 3:54.50.
Allen reached the 100m breaststroke semi-finals in 15th but Hannah Miley did not make the top 16.
Jaz Carlin and Ellie Faulkner were ninth and 16th respectively in the 400m freestyle heats - the former missing out by just 0.02secs - while Ieuan Lloyd and Robbie Renwick missed out in the men's equivalent in 15th and 30th.
Lloyd also missed out in the 200m individual medley along with Rob Pavoni.
