Pat Smullen steered the Willie Mullins-trained Renneti to a clear-cut success in the Group Three Loughbrown Stakes at Naas.
The eight-year-old bolted up in a conditions race at the Galway Festival, but had since finished down the field in the Irish St Leger Trial and a valuable handicap at Leopardstown.
Back in a smaller field, he was the 4-5 favourite to get his season back on track and saw out the two-mile distance well to score by five lengths.
Stars Over The Sea was a clear second.
Mullins confirmed the Qipco British Champions Long Distance Cup could be Renneti's next port of call.
He said: "Hopefully at this time of year he will keep getting the ground he likes with plenty of dig in it.
"He'll probably stick to this sort of trip and he could go for the race in Ascot."
