The UCD scholarship student made four birdies in a three over 75 to climb to tied 18th as team mate Jessica Carty shot a 79 to go into the final round in 29th place in the women's event at Barranquilla Country Club.
In the men's competition, Claremorris' Stephen Healy - reunited with his golf clubs after they were delayed in transit - also shot a three over 75 to move to joint 26th.
He's 14 strokes behind co-leaders Jimmy Mullen (72) and Paul Howard (75) of England, who lead by a shot on one under par from Argentina's Alejandro Tosti.
Tullamore's Stuart Grehan, who is a sophomore at Eastern Michigan, looked on course to card a sub par round but ended up with a level par 72 that leaves him tied for 32nd on 15 over.
"Unfortunate day," Grehan tweeted after his round. "Two plugged balls in the rough and also stuck in a cactus!"
Finland's Oona Vartiainen (76) and Scotland's Gemma Dryburgh (76) lead the women's title race by two strokes on 10 over par from Argentina's Ayelen Irizar and Peru's Lucia Gutierrez.
