Royal Dublin's Niall Kearney (70) and Whitehead's John-Ross Galbraith (71) are tied for fifth place on six-under, just four shots off the lead in the race to make the top 19 and tied at Frilford Heath.
Paul McBride is three shots outside the top 19 after a 74 with Dermot McElroy’s 73 leaving him a shot further back while Cork’s John Hickey missed the cut
At the First Stage of the Korn Ferry Tour Qualifying Tournament, Stephen Grant is just three shots outside the top 21 who progress after a 69 at Breakers Rees Jones in West Palm Beach but Ruaidhri McGee's 73 at Grasslands left him 10 shots outside the top 23 there with a round to go.
