Fame And Glory is now favourite on Betfair for the Irish Champion Stakes as wet weather continues to put the clash with Sea the Stars in doubt.
The runaway Irish Derby winner is into 10-11 on the exchange, with 2000 Guineas and Epsom Derby hero drifting to 13-8.
Betfair spokesman Tony Calvin commented: "It has been bright and dry at the course on Tuesday but unfortunately the Betfair market suggests that the clash of the superstars at Leopardstown on September 5th is looking increasingly unlikely.
"In truth, there is not a great deal of depth in the market, due to the fact that Sea The Stars won't be risked on the soft ground that many are forecasting. And his absence would render Fame And Glory a 1-3 chance, at best.
"But with every other bookmaker declining to price up the race, it's the only, and best, betting guide that punters have at the moment."
