Costello claims victory in Spain

Olivia Costello has won the Triple A World Series Final 2025 by 14 shots as the Roscommon golfer proved far too strong for the rest of the field.

Costello, who celebrates her 17th birthday today romped to victory after a final round of four over par.

With weather conditions making the course play difficult for all players, Costello built on her seven stroke lead to secure a highly impressive win in the U-21 age grade.

This wasn’t as pretty as the eight under par round of 64 yesterday but the Roscommon golfer was able to canter to victory.

She birdied the second, sixth and 17th holes during her final round on a weekend where she simply dominated the field.

Her four over par round of 76 saw her end the tournament on 2 under par and 14 shots ahead of the field as she added to her runners up at the Spanish Open Amateur Championship last month with this highly impressive win.
