In the men's 100m, Riku Illukka finished fourth in the opening heat in a time of 10.57, just over three tenths down on his personal best but facing a head wind. He had a nervous wait during the next two heats before it was finally confirmed he had taken the 12th and final qualifying spot for the evening's semi-finals.
Finland had three entrants in the 110m hurdles - first up was Ilari Manninen who was sharp out of the blocks but clipped later barriers and lost his rhythm, finishing sixth in a time of 14.13.
However, there was better to come for Finnish fans, as Elmo Lakka then put in a smooth run and finished fourth in heat two in 13.84, before Santeri Kuusiniemi also came fourth in the last heat, clocking 13.89 which was enough for him and Lakka to both reach the semi-finals, which take place on 12th August in the evening session.
Another three Finns were on the starting blocks for the men's 400m hurdles, but only one will be back for the semi-finals on 12th August - Antti Sainio tracked his heat winner Julien Watrin well down the outside and recorded a season's best time of 49.70 and finished third.
Jere Haapalainen also ran a season's best of 50.37 from the outside lane in the opening heat, but the former European junior champion still came in eighth and last place, before a 50.90 run from Tuomas Lehtonen in the final heat was enough for sixth, but not to progress in the competition.
No joy in the field, middle distance or women's hurdles
The men's discus competition getting underway meant an appearance for Mico Lampinen, who began qualification group A with a 53.83m throw before improving to 56.47m with his second attempt to move into seventh place for the moment. However, he was soon surpassed and by failing to improve with his third attempt, he finished 13th in group A and short of the qualification mark.
Finnish champion Eveliina Maattanen was on the track for the opening heat of the women's 800m, and having stayed in the middle of the pack for the first lap, she struggled to stay with the increased pace in the second half of the race, and dropped to last place just before the finish line. There will be no semi-final place for the 30-year-old, but a season's best time of 1:59.62 will be something of a consolation.
A time of 55.93 in Monday's heats had seen Heidi Salminen comfortably into the semi-finals of the women's 400m hurdles, but she struggled to replicate that against tougher opposition, finishing in a time of 56.39 which was only enough to hold off Denmark's Martha Rasmussen and finish seventh. Italy's Ayomide Folorunso finished first in a time of 53.93.
Having been given a bye to the semi-finals, Finnish champion Hilla Uusimaki then took to the track in the next race. A strong start saw her lead over the first three barriers, and though she was passed on the inside on the final bend, a strong finish meant she stopped the clock at 54.70 to take fourth place, as world bronze medallist Emma Zapletalova took the win in 54.09. However, it was not enough for Uusimaki to take one of the fastest non-automatic qualification places.
In the men's high jump qualification, Daniel Kosonen cleared 2.15m but three fouls at the next height saw him bow out in 18th place.
Finnish women take centre stage in evening session
In the evening session on Tuesday 11th, Saara Keskitalo and Lotta Harala will be in action in the 100m hurdles semi-finals, with the final set to take place later in the evening. Saga Andersson and Wilma Heltela will be wearing Finnish colours in the women's pole vault qualification, while Nathalie Blomqvist and Aino Suni will be in the final of the women's 5000m.
