The 2018 champion is best price 9/2 to retain his crown.
Tiger Roll could be the shortest price winner of the Grand National for a century if he obliges as favourite on April 6th.
Currently best price 9/2 with Black Type, you have to travel back 100 years to find a winner at slimmer odds, when Ernie Piggott rode Poethlyn to victory at 11/4 favourite.
Furthermore, Gordon Elliott’s stayer is as short as 3/1 and if he goes off at slightly shorter – which is unlikely, but possible given his popularity - he will be the joint-shortest price winner of the Grand National ever, equalling the odds of the 1919 champion.
The records won’t stop there either, as Tiger Roll would become the first back-to-back winner of the Aintree showpiece since the great Red Rum in 1974. He would, however, still be one off Ginger McCain’s superstar’s record three victories in the race.
Going back to popularity, Tiger Roll has been the subject of 1 in 4 punts on the Grand National in last 30 days, receiving a mammoth 26.2% of bets on the market. To put that figure into perspective, the second most backed is the Willie Mullins-trained Rathvinden with 5.76%.
Oddschecker spokesperson, George Elek: 'Tiger Roll is quickly becoming the star of National Hunt racing, and he can truly etch his name in the history books should he defend his Aintree crown.
'Whilst 9/2 may seem a prohibitive price in a race of this nature, he has truly proven his class since being sent off 10/1 last year.'
