John Fitzsimons earned a second place finish in the 800m at the Diamond League meeting in Stockholm.
The Kildare native ran a time of 1:46.80, with Britain's Ben Pattison winning by 0.74 seconds.
Elsewhere at the meeting, Ireland finished third in the women's 4x100m relay. The team consisting of Lauren Roy, Sarah Leahy, Kate Doherty and Stephanie Adeyemi Talabi ran a season's best time of 44.25 seconds as the Swiss and Finnish quartets took first and second respectively.
Sarah Lavin, who won her seventh Irish national title in Santry on Saturday, was fourth in the women's 100m hurdles in a time of 13.13 seconds.
Andrew Coscoran and Sarah Healy both finished sixth in their respective 1500m events and the men's 4x100m relay team of Israel Olatunde, Mark Smyth, Colin Doyle and Joseph Ojewumi also finished sixth.
Elswhere at the Stockholm meeting, Swedish Olympic champion Armand Duplantis set an outdoor pole vault record of 6.16m, breaking his previous best of 6.15 but four centimetres short of his world record, set indoors, of 6.20m.
The 22-year-old soared to an easy victory in the competition before having the bar set at 6.16, and he cruised over it at the second attempt to delight the home crowd.
American Chris Nilsen tried to push Duplantis all the way, but the Swede responded to every successful jump by his rival before taking a run at the old outdoor mark.
The men's 100m race was robbed of its biggest name when Olympic champion Marcell Jacobs, who was due to make his first Diamond League start of the season, pulled out due to injury.
In his absence, South Africa's Akani Simbine cruised to victory in a time of 10.02 seconds at the final Diamond League meet ahead of the World Championships, which get underway on 15 July in Eugene, Oregon.
On a muggy night at the stadium built for the 1912 Summer Olympics, Femke Bol set a Diamond League record in the women's 400m hurdles, blazing away from the rest of the field to win in a time of 50.27.
Alison Dos Santos of Brazil crushed the field to win the men's 400m hurdles in a time of 46.80, becoming the first man to break the 47-second barrier this season.
Dominic Lobalu also set the best time of the season with a blistering spurt on the home straight to win the men's 3,000m in a time of 7:29.48, seven-hundreths of a second ahead of Jacob Kiplimo.
Despite a banner night for Duplantis, it wasn't all plain sailing for the Swedes as their Olympic discus champion Daniel Stahl came in a disappointing third, behind Kristjan Ceh and Mykolas Alekna.
