Mullins has four entries in Grand National Willie Mullins relies on four horses in the entries for the Crabbie's Grand National at Aintree on Saturday. The Closutton handler is going all out to wrest the UK trainers' title and pins his hopes of winning the National a second time after Hedgehunter in 2005 with On His Own, Sir Des Champs, Boston Bob and Ballycasey. However, the shortest-priced Irish horse in the ante-post markets is Gordon Elliott's Cause Of Causes, while last year's Midlands National hero Goonyella and Tony Martin's Gallant Oscar are also shorter in the betting than Mullins' apparent main hope Boston Bob. Other Irish hopes include Pat Fahy's Cheltenham fourth Morning Assembly and Elliott's Ucello Conti, who finished third in the Thyestes last time.
