Jonbon already sat as favourite for the Supreme Novices' Hurdle heading into Fridays Ascot run, however quickly saw his price take a further tumble on the back of an ultra impressive Grade 2 win in the Howden Kennel Gate Novices' Hurdle.
A £570,000 purchase and full brother to the top class hurdler Douvan, Jonbon was an easy 15 length winner of his Irish PTP and subsequently went on to cosily land his sole bumper start on his first run for Nicky Henderson.
He then marked his debut over obstacles at Newbury, on the back of a 244 day break, with a cracking performance, winning by an eased down six length margin in November this year.
The step up in grade on Friday proved little issue to this son of Walk In The Park, winning once more, eased down at the finish, and completing his four timer to remain unbeaten under all codes.
The Supreme Novices' Hurdle Market has now knocked him down a few more points on the back of that most recent win; he's now as short as 2/1 from the previously available 7/2.
