Dundalk's Caolan Rafferty and Massereene's Tiarnan McLarnon came from behind to capture the Copa Fedegolf by a massive 12 strokes at Barranquilla Country Club in Colombia.
The Irish internationals went into the final round one stroke behind Argentina's Sebastian Bergagna and Horacio Carbonetti in the team standings.
They were three behind Bergagna and Carbonetti after six holes but stamped on the gas for the remainder of the round to win the team title comfortably on one-under 575.
"It was good," Rafferty reported. "The key was that we both played solid because it isn't easy to get two lads shooting good scores for four rounds.
"Most of the other teams had one good and one poor score each round."
Rafferty was three strokes behind Chile's Lucas Rosso with a round to play after rounds of 75, 69 and 70 but closed with a six under 66, finishing with a birdie at the last to edge out his rival by one stroke for the individual title on eight-under 280.
"I played really well," Rafferty said. "I missed a lot of putts over the week with the greens being so different."
McLarnon was eighth on 221 through 54 holes after 74, 72 and 75, then closed with a 74 to finish sixth on seven-over.
