Phil Healy was placed fourth in her 200-metres semi-final at the European Athletics Championships and as a result failed to progress to the final.
Irish record holder Healy clocked a time of 23.23 which was faster than the 23.34 she posted in Friday morning's heats.
That time placed her 11th overall.
The semi-final was won by Dafne Schippers of the Netherlands in a time of 22.69.
Afterwards, Healy told RTÉ Sport: "I'm really really happy with that after running my third fastest time ever. It was much better than this morning's run and I will be ranked higher overall going away from this championship.
"There was a little bit of tiredness in the legs but I'll build on this championship and look forward to the next one.
The Europeans Indoors will be the main target again over 400m and I'll vary it again over the summer."
Ciara Mageean comfortably qualified for the 1500m final with second place in her heat, clocking 4:09.35 behind Britain's Laura Muir (4.09.12).
Mageean runs in the final at 8pm on Sunday.
The Portaferry women won bronze at the last European Championships in Amsterdam in 2016 and will be confident of contending for a medal after her performance today.
"I'm happy with that," Mageean told RTÉ Sport. "I came here for the big Q. So now to get back and get recovered and ready for that final.
"I've had a lot of changes the past year, even the past six months, with my move to Manchester.
"I'm feeling good, I'm feeling confident and I'm feeling happy and that's a nice recipe for an athlete.
"I don't come into a championships unless I believe that I'm going to go and give 100% and hopefully that will reap the rewards that I want."
Ireland's men missed out on a place in the 4x400m relay final after finishing fifth in their semi-final.
Christopher O’Donnell, Brandon Arrey, Leon Reid and Thomas Barr finished in 3:06.55, which wasn't enough to claim the fastest loser place in the final.
Ireland's 4x400m women's team of Sinead Denny, Sophie Becker, Davicia Patterson, and Claire Mooney were eighth in their semi-final in 3:35.96.
Kerry O'Flaherty finished 17th in her heat of the 3,000m steeplechase in a time of 10:09.81. Michelle Finn was 16th (10:10.93) in the second heat of the same event.
