Paul Dunne cruised into the last eight of the US Amateur Championship last night after a superb day's work.
Straight hitting and clear thinking helped Dunne, 22, ease to a 3&2 win over 17-year old American Caleb Proveaux in the last 32 clash before an even more impressive performance in the last 16.
The University of Alabama-Birmingham graduate then took his third round clash with Colorado's David Oraee last night by the same scoreline.
The pair split the first five holes with two wins and a half apiece, however, Dunne seized control with a par and a win on the sixth hole and held the lead thereafter.
With Dunne 2 up, Oraee closed the gap by winning the 13th hole, however he bogied the next two meaning that a birdie and a par were enough for Dunne to go 3 up and win 3&2 on the next hole.
Dunne now faces US Walker Cup star and Amatuer world ranked number 7 Bryson DeChambeau in today's quarter-final. DeChambeau is one of just three of the world's top 10 remaining in the event.
And with England's Sam Horsfield beaten 2 and 1 by American Daniel Wetterich, hopes of a record five Irish players making the Great Britain and Ireland side are now high.
Dunne, Gary Hurley, Gavin Moynihan and Cormac Sharvin are considered certain picks by most observers and it remains to be seen if Naas' Jack Hume is chosen by captain Nigel Edwards and his selectors - Welshman Andy Ingram, Scotland's Gary Hay and Tramore's Michael Burns - is now the big question.
Elsewhere, Tiger Woods fired a six-under-par 64, his lowest opening-round score of 2015, to lie two shots off the lead at the Wyndham Championship and boost his hopes of qualifying for the FedEx Cup.
The former world No 1, who missed the cut in a Major for the third time running last week, mixed seven birdies with one bogey to move within two strokes of clubhouse pacesetters William McGirt and Erik Compton.
Woods only recently committed to the Wyndham, the final event of the regular season on the US circuit, as part of a last-ditch effort to earn extra FedEx Cup points.
The 14-times Major winner is 187th in the FedEx Cup standings and needs a victory to qualify for the lucrative four-event play-off series that starts in New Jersey next week with The Barclays.
On the European Tour, David Horsey shot a course record 63 to claim the first-round lead at the Made in Denmark tournament, with Peter Lawrie the best of the Irish, three shots behind.
