An emotional Mexico team were crowned Nations Cup champions of the Stena Line 2018 Dublin Horse Show.
Ireland finished in a tie for second place after a thrilling jump-off, in which the Mexicans triumphed, booking a place at the world championships in Tryon, North Carolina next month.
It was particularly emotional for Mexico team member Federico Fernandez, who survived the 1988 Mexican air crash where over 50 people died.
"This brings tears to your eyes," Fernandez said.
"We have had the best Nations Cup ever, we haven't stopped dreaming about this moment."
Mexico finished on a score of eight faults to win, with Ireland, Italy and France all finishing on 12 faults and sharing second place, while GB were sixth.
It was a thrilling finish as, with the last line of riders left to jump, Ireland, France, Mexico and Italy were tied.
Ireland's Cameron Hanley was last to jump and, had he gone clear, Ireland would have gone to a jump-off, but a fault at the combination handed Mexico victory.
Rodrigo Pessoa, Ireland's chef d'equipe, said: "We came close and, one thing is for sure, we will be back next year to try again."
Meanwhile, Stewartstown's Gareth Swail won the highly coveted 3,000 gelding loose jumping final on Brian Hutchinson's SVS Valiant.
Hutchinson was the overall champion and will now produce the horse under saddle.
Randalstown's Samuel McAteer produced the heavy cob winner with Randalstown Cromwell, and was runner-up with Randalstown Raffles in the lightweights.
Vice President of the Balmoral Show Diane Gibson took to the saddle for the heavy hunters section and finished runner-up.
Randalstown chemist Sam Smyth kept Co Antrim in contention, taking second in coloured horses with Ballylurgan Ferro, who went on to win reserve championship of his section, and Alice Power, on Bear Me In Mind, won the 138cms National Pony Showjumping Championship.
Max Foley's Pumpkins Pondi, a 15-year-old 148cm pony stallion owned by Ger Foley, received the RDS Championship trophy after a six-pony jump-off from 14 finalists, while Ryan Sweetnam on Kilcummin Cruise, owned by Patrick Finn, won the six and seven year old 148cms ponies in 35.92.
