The Philip Hobbs-trained Chance du Roy is 8/1 favourite (from 10/1) with the sponsors to win his second Betfred Becher Chase at Aintree this weekend.
Balbriggan, who landed a big gamble in the Troytown last month, is next in the betting at 9/1 (from 10/1), ahead of the well backed Goonyella at 10/1 (from 14/1).
Betfred spokesman Andrew Griffiths said: "Chance du Roy is a tough nut to crack over the National fences and he's a deserved favourite to win a second Betfred Becher.
"Ante-post punters have been chipping away at Goonyella since the entries were revealed and he would be our worst result at this stage."
