Denis O'Sullivan leads the Irish contingent after the first round of the Kingdom of Bahrain Trophy at The Buckinghamshire.

The Cork ace, who will pass the €1 million mark this week, hit a one under par 71 to trail leaders John Chillas and Adan Sowa by four shots in a share of 15th place.

Des Smyth had to settle for a one over par 73 while Eamonn Darcy is tied for last place with Tommy Horton after a five over par 77.
