Punters pile on Gold Cup winner Synchronised for Grand National The Cheltenham Gold Cup winner, who is trained by Jonjo O'Neill, shortened into 7-1 favourite from 10-1 and his price is predicted to contract further in the run up to the big race, especially as A P McCoy will ride. Frank Berry, racing manager to owner J P McManus, said: "At the moment, the plan is to go [to Aintree] with Synchronised. Just one more bit of work, and if Jonjo is happy then he'll go. The David Pipe-trained Junior, the one-time favourite, has meanwhile drifted in the market, with Betfair customers offering as big as 15-1 yesterday, before the price settled at a more realistic 13-1. Katie Walsh will have her first Grand National ride aboard Seabass, a 16-1 chance, for her father Ted. Wayne Hutchinson will ride West End Rocker, but Midnight Chase will not be in the line up after connections decided he has done enough for the season. McManus will have five runners in Monday's Irish Grand National at Fairyhouse, including the McCoy-ridden Groody Hill. But Nina Carberry is tipped to win the race for a second time when she rides Lastoftheleaders, trained by her uncle Arthur Moore.
