Kilkenny-native James Dwyer added a sixth place in the individual freestyle test - grade IV to his team bronze medal at the Paralympics this morning, riding his 16-year-old gelding Orlando.
In gold medal position on a score of 74.400 from the halfway mark of the grade IV competition, the 42-year-old saw his lead gradually eroded, with gold eventually going to Belgium's Michele George and Rainman with a mark of 82.100.
Britain took silver, Sophie Wells scoring 81.150 on Pinocchio.
Bronze was taken by Frank Hosmar of the Netherlands with Alphaville, on a mark of 78.600.
Dwyer has been based in Unionville, Pennsylvania, in the United States for some years, and with his Dutch-bred horse has achieved numerous successes in para-equestrian dressage, the most notable before the Paralympics being a fifth-placed finish in the 2010 World Equestrian Games.
Equestrian team manager Dara Kearney said after the event: "I was very pleased with James Dwyer’s performance.
"James rode superbly achieving a personal best.
"He gave it everything, had no wrong moves and the score speaks for itself."
Irish silver medallist Helen Kearney and fellow team member Geraldine Savage will compete in the grade 1a freestyle later this afternoon.
