Ireland's Eilish Byrne improved on her Thursday team test score to finish fifth in the individual para-dressage final at Greenwich Park in London.
With her chestnut gelding Youri, the Dundalk-born rider returned a score of 73.429 percent to place her fifth in the world in the Paralympic grade II.
Speaking after the competition, she said: "I'm just over the moon, I can hardly believe it. We are all delighted."
Byrne's individual mark will be added to the team test score from Thursday to help decide Ireland's overall team placing when the remaining three riders - Helen Kearney, Geraldine Savage and James Dwyer - complete their individual championships tests tomorrow. Ireland currently lies in sixth place as a team.
Like the other riders, Armagh-based Byrne will have a further chance to qualify for a medal when the freestyle competitions take place on Monday and Tuesday, when all competitors begin on a zero score.
