Michael Jamieson and Andrew Willis remain on course to complete a Bath Intensive Training Centre medal double at the World Swimming Championships.
The pair qualified fifth and third fastest respectively for tonight's 200m breaststroke final in Barcelona.
Jamieson won Olympic silver over the same distance a year ago yesterday, while Willis has reached the final in a major global competition in each of the last three years.
Having won his morning heat, Willis took the touch again in 2mins 09.11secs and will be aiming to improve on the eighth-place finish he achieved on his Worlds debut in 2011.
"That felt good - it was nice and controlled," said Willis, who also finished eighth at London 2012 last year.
"I'm finding it quite easy to go out at the moment so I kept it nice and long in that second 100m and tried to build it a little bit. It will be interesting to see my stroke rates and splits.
"I've done what I need to do to make the final and it's anyone's game.
"I'll need to improve on that time but I'm feeling fairly confident."
After coming through the heats 14th fastest in 2:11.47, London 2012 hero Jamieson upped his game in the semis to clock 2:09.62 from lane one.
And the 24-year old – who finished fifth in Shanghai two years ago – is certain he will need to improve again if he is to land his first medal at a Worlds.
"I'll need to find a little bit more for tomorrow though because 2:09 isn't going to cut it for the medals," said Jamieson.
"Heat swims are always touch and go but I felt a lot better tonight and I want to be able to step it up again tomorrow.
"I'm experienced enough now not to worry about things like a bad heat. As soon as I was finished this morning, that was it.
"I didn't give myself a good lane draw for tonight but it forces you to stick to your own game plan if you're in an outside lane so it was fine."
Felllow Bath swimmer Chris Walker-Hebborn missed out on a place in the 200m backstroke final, finishing 13th overall after clocking 1:58.16 in his semi. British team-mate Craig McNally did progress as the seventh-fastest swimmer.
