Review navan 5th Dec Osana did his Arkle Trophy claims no harm when following up his gritty fencing debut success with a more polished display in the Irish Stallion Farms EBF Novice Chase at Navan.Edward O'Grady's inmate was sent off the red-hot 2-5 market leader and was immediately sent to the front by Andrew McNamara.After jumping economically throughout, the favourite was eased down to record a 12-length victory over Dancing Tornado, who paid for making a bad mistake four out.Stamina won the day in the Proudstown Handicap Hurdle as the Niall Madden-ridden Operation Houdini (9-4 favourite) battled to a short-head success over Mythical Prince.The latter looked to have sealed it when getting his head in front jumping the last, but Davy Fitzgerald's inmate would not surrender and held a narrow advantage as the pair flashed past the post together.David Casey took top honours aboard Glenstal Abbey in the Kilberry Novice Hurdle.Charlie Swan's charge made no impression in the Greatwood at Cheltenham last month but he bounced back in no uncertain terms.After hitting the front when favourite Quinola Des Obeaux started to weaken three from the finish, the 5-1 shot cruised home by three and a half lengths from Quito De La Rouqe.Where's The Dosh (4-1) maintained his improvement when taking the Kells Maiden Hurdle.Liam Burke's charge was settled in midfield early on but came with a well-timed run coming to the second-last and held the challenge of Mexican Venture by three lengths under Davy Russell.Russell doubled up on the Dessie Hughes-trained Magnanimity, who got the better of Lucky William in the Irish Stallion Owners EBF Maiden Hurdle.The pair had it between them approaching the second-last flight and although favourite Lucky William looked a little unlucky when denied a clear run up the rail close home, Magnanimity (2-1) stayed on to record a one-and-a-half-length triumph.Jim Dreaper's Telenor justified 6-4 favouritism under Andrew Lynch with a 13-length defeat of market rival Lurgan in the Navan Golf Course Beginn
