The Last Samuri, second in last year’s Grand National, bids to complete his preparations for this year’s race when attempting to land the Betbright Grimthorpe Chase at Doncaster tomorrow afternoon.

Trained by Kim Bailey and ridden by David Bass, the nine-year-old has run twice since his Aintree efforts of last April.

Last time out he was third in the Becher Chase over the Aintree obstacles in December, in a race won by current 2017 Grand National favourite Vieux Lion Rouge.

Tomorrow’s 10-runner feature at 3.35pm also has the Brian Ellison trained Definitely Red in the line-up under Danny Cook. The gelding unseated in the Peter Marsh Chase at Haydock in January having previously won the Rowland Meyrick Chase at Wetherby on Boxing Day.

The Venetia Williams trained Yala Enki was fourth in that Boxing Day race having previously won the Tommy Whittle Chase at Haydock and the seven-year-old also takes his chance.

Nicky Richards also has a chance with Looking Well, under five-pound claimer Ryan Day, runner-up in the Sky Bet Chase at Doncaster in January.

While the Grimthorpe is the feature of four races shown live by ITV Racing, the 3pm Mares’ Hurdle also looks competitive.

Hat-trick-seeking mare Lastbutnotleast, under Will Kennedy for Donald McCain, is well fancied, the seven-year-old successful at Carlisle and Hexham this season.

Kerry Lee runs Happy Diva, the likely market leader under Jamie Moore, the mare a Sandown runner-up three weeks ago after wins at Wetherby and Fontwell.

Another field of six goes in the 2.25pm Betbright Chase, the race headed by Paul Nicholls’ San Benedeto under Nick Schofield, who was a recent Musselburgh winner.

Pauline Robson sends out Katgary, under Henry Brooke, off the course since winning at Perth in June.
