Having never previously raced beyond ten furlongs, Conor Pass was moved up sharply in distance to contest the Irish St Leger over one and three quarter miles at the Curragh on 22 September. Ridden by Paul Jarman he was made the 5/1 second favourite behind the British-trained Sunyboy, while the best of the other five runners appeared to be Barclay Joy, Star Appeal and Park Lawn. After turning into the straight in second place, Conor Pass took the lead two furlongs from the finish and held off the sustained challenge of Sunyboy to win by three quarters of a length with a gap of eight lengths back to Star Appeal in third. He was then shipped to the United States to contest the Washington, D.C. International but was injured shortly before the race and did not take part.
