France's Anne-Lise Caudal and American Alison Walshe lead the field by one shot after the first round of the Ladies Irish Open at Killeen Castle in Dunsany.
The pair carded six-under-par 66s to lie ahead of South Africa's Lee-Anne Pace, Sweden's Maria Hjorth and Spain's Azahara Munoz Guijarro.
Caudal carded two eagles at the par-five second and seventh holes, five birdies and three bogeys in an eventful round.
Walshe had seven birdies and a single bogey.
Seven players were in a tie for sixth place on four under, including American Kim Welch, who would have been in a share of the lead were it not for a double bogey six at the 17th.
Lisa Maguire leads the Irish contingent on one under.
