Keith Horne, Jaco van Zyl and Shaun Norris joined Hennie Otto at one-under-par to form part of a 25-way share of 44th after round one in the Irish Open at Killarney Golf and Fishing Club.
Morning starter Otto paved the way with his score of one-under and was soon joined by Horne before countrymen van Zyl and Norris closed the day.
The afternoon trio all carded double-bogeys, yet overcame the deficit, and coincidentally all three moved to one-under with a birdie on the 16th.
Shaun Norris displayed solid focus when he recovered from consecutive double-bogeys on the fourth and fifth holes and managed to reach the turn at one-under despite four dropped shots.
Norris made birdie on the notably difficult par-three sixth hole before jubilantly adding an eagle to his scorecard after the seventh during his rollercoaster front nine.
Jaco van Zyl did well to recover his round after making the turn at two-over, carding a bogey-free back nine that included three birdies.
Keith Horne carded a stable round, the low was a double-bogey on the 444 metre par-four 11th, but birdies on the 14th and 16th recovered the dropped shots.
Despite a large number of British entries and much hype over the quality of the local players, at the close of day one at the Irish Open no player in the top five is from from the United Kingdom.
The South Africans sharing 44th will begin the second day determined to not drop their focus whilst in KillarneyÂs rough.
