Siblings Sam and Chloe Magee had to settle for badminton mixed doubles bronze after losing their semi-final to French pair Gaeten Fontaine and Audrey Mittel.
The Magees rallied in the second set, but were beaten 21-12 23-21, giving Sam a second bronze medal having also reached the podium with brother Josh in the men's doubles on Friday.
And the Letterkenny 25-year-old pronounced himself "over the moon" with his haul after revealing he had been struggling with a back injury since arriving in Baku.
Magee said: "I injured my back and the doctor told me I had to pull out, but the team said to come just to see what I can do.
"I had no expectations at all. A week ago I couldn't bend my back forward and I had given up on my dream of winning a medal. But once you get that close to gold, you want more."
