SAM STEPS UP ON WALK

SAM WALEY-COHEN is relishing the chance to ride Walk In The Mill — a “last-minute addition” to today’s Grand National.

The Robert Walford trainee came in as a third reserve after the scratching of Beeves and Waley-Cohen (left), who has won six races over the famous fences – and finished second in the 2011 National aboard Oscar Time — said: “He’s a last-minute addition but he jumps well and has got some decent form, so we will give it a shot.”
