Dermot Weld believes the five remaining all-weather meetings at Dundalk this season could swing the jockeys' championship in favour of Colin Keane.
Keane is currently locked in an absorbing tussle with nine-time champion Pat Smullen, with whom Weld has enjoyed such extraordinary success over the years.
But the Rosewell House handler told The Irish Times: "I don't have that many fresh horses left to run.
"There are only a small pool of three-year-olds and a number of backward two-year-olds.
"I don't have a huge supply for Pat and I imagine he may find it difficult.
"I think Dundalk could prove to be a key factor in the championship.
"I don't have too many for those meetings and despite Pat's excellent riding at Dundalk the pendulum could swing in Colin Keane's favour there.
"They are two world-class riders. We are lucky to have the two of them in this country.
"I have the height of regard for Colin Keane. He is an excellent young rider. It will be very close."
