A one under 72 left Denis O'Sullivan as the best of the Irish after the opening round of the Dutch Senior Open at The International in Amsterdam.

The 66-year old Corkman is tied for 10th, four strokes behind Phil Golding, who carded a five under par 68 to continue his run of good form a week after winning the French Riviera Masters.

The Englishman finished the day one shot clear of Argentina’s Jorge Berendt and two in front of Jerry Bruner, George Ryall and European Senior Tour debutant Chris Van der Velde.

Former Ryder Cup captain Ian Woosnam opened with a two under par 71 at a course he co-designed and shares sixth place with Tim Thelen, Angel Franco and Rick Gibson.

Des Smyth had four birdies in a one over 74 to share 22nd spot with Ronan Rafferty's haul of three birdies and six bogeys for a 76 leaving him tied 37th.

Philip Walton, still seeking his maiden win in the over 50s ranks, posted a four over 77 to find himself tied for 44th on four over.
