JPR One is the favourite to win the Betfair Hurdle at Newbury on Saturday but there have been big moves for other horses in the market, adding to the sense that the race is wide open.
Colin Tizzard's five-year-old is 9/2 on the Betfair Sportsbook while money is starting to come into the market on the Exchange.
There has also been support in recent days for Fifty Ball, in from 16/1 to 9/1, as last year's runner-up bids to go one better in 2022.
Fifty Ball lost out to Soaring Glory 12 months ago and he's 13/2 to become the first horse to win the race in consecutive years since 1964.
More fancied in the market is Broomfield Burg, the Nicky Henderson six-year-old that's 5/1.
You can read Betfair Ambassador Paul Nicholls' guide to all of his Saturday runners on this site tomorrow, including Knappers Hill who is 6/1 in the Hurdle.
Nicholls' Clan Des Obeaux is 10/11 to win the Betfair Denman Chase earlier on the card and is expected to face competition from Royal Pagaille 5/2.
Our ambassador's Hitman, meanwhile, is locked in a two-way battle with Alan King's Sceau Royal for favouritism in the market for the Betfair Game Spirit at 15:00. Both horses are 2/1.
