The 22-year old Greystones golfer sent a 104-yard wedge into the bottom of the cup and then holed a 40-foot second-hole birdie in an eventual round of a three under par 68 in ideal conditions on the Oceanico Victoria course.
Dunne was sharing 22nd and just four shots behind leading duo of England’s Andy Sullivan and Belgium’s Nicolas Colsaerts when poor light halted play.
Dunne raced to six under par through eight but found the water with a drive at his ninth ahead of completing his remaining nine in one over par. “It’s the first time I’ve started a round with an eagle as my home course commences with a par three, and then to hole a 40-footer for birdie at the next was a great start,” he said. “But then after taking the double on my eighth I burned the holes on a few occasions coming in so it could have easily been a lot lower but a 68 is a good start.”
Kells’ Damien McGrane finds himself the leading Irish player and capping his round of a four under par 67 highlighted by chipping-in from 35-feet for eagle from rough at the par five 17th.
Pádraig Harrington and Kevin Phelan recorded one under par 70s, Darren Clarke a 71 and Michael Hoey a three over par 74. Peter Lawrie, at two over through 17 holes, is among 14 who resume their first round this morning
