Killarney's Tommy O'Driscoll closed with a five under 67 to finish fifth in the Copa Andalucía at the Real Club de Golf Guadalmina near Marbella.
The 19-year old (71-71-77-67), who plans to play on the Alps Tour this year, made six birdies and just one bogey on the final day to end the 72-hole event on two under par.
The former Boys international finished a massive 10 strokes behind world amateur No 19 Ivan Cantero, who closed with a 66 to win by an impressive eight shots from compatriot Pablo Heredia on 12 under par 276.
Naas' Conor O'Rourke (75-72-70-71), called up to the Irish senior panel for 2016, had five birdies in a one under par 71 to claim a creditable seventh place on level par 288 with clubmate Jonathan Yates (74-82-71 -80) slipping to 50th after a closing 80.
O'Driscoll had a good day on the greens thanks to the green-reading skills of his brother Eamonn, who carried his bag having missed the cut.
