Ireland’s James Dwyer, originally from Carrigeen in Co. Kilkenny, claimed fourth place in the Grade IV para equestrian dressage competition at Greenwich Park, London.
Dwyer, who is now based in the US, rode gelding Orlando to a score of 69.719, fourth best of 14 competitors in his class.
Louth’s Eilish Byrne, Ireland's first competitor at the Games in any sport, finished seventh place yesterday morning.
The remaining two dressage riders, Helen Kearney and Gerry Savage, compete later today in the last of Ireland's team tests, which will give a provisional overall team score made up of the best three results.
The individual championship tests then run through to Tuesday - where the three best team scores are also added to make the final mark.
