Forrest Little's Eoin Arthurs took advantage of perfect early morning conditions to scorch to a six-under par 66 and a two stroke lead in the East of Ireland Amateur Championship at County Louth.
The 24-year-old from Swords fired two eagles, five birdies and just three bogeys on the fast-running links as the Castle's Dara Lernihan posted an afternoon 68 that featured an eagle two at the 454-yard first, his 10th.
Belvoir Park’s Harry Diamond finished with five straight birdies from the 14th to match Walker Cup star Jonny Caldwell with a 69 while the Curragh's Paul O'Hanlon had a hole-in-one with a six-iron at the 207-yard 17th, his eighth, en route to a two-under par 70 that was matched by Michael Buggy and Niall O'Connor.
Only 18 players broke par as the firm conditions and slick greens took their toll on the 156-man field.
All but three of those scores came in the morning but reigning Irish Close and West of Ireland champion Shane Lowry failed to take advantage, carding a level par 72.
