BIG ZEB out to 4/1 (from 11/4) after defeat at Punchestown.

Race winner GOLDEN SILVER halved to 8/1 (from 16s - including NON RUNNER NO BET AT LADBROKES) for the Queen Mother Champion Chase - and 6/1 for the Ryanair.

Hayley O'Connor of Ladbrokes said: "Golden Silver mugged the odds-on favourite and was a worthy winner but we're not sure Cheltenham in Spring will suit him as much. Big Zeb remains half his price for the Champion Chase and we've far from written him off."

GRANDS CRUS still 3/1 with the sponsors for the Ladbrokes World Hurdle after devastating Cleeve Hurdle win

David Williams of Ladbrokes said: "Punters have taken plenty of the 3/1 about Grands Crus for our race but Big Bucks fans are beginning to take advantage of the 4/6. It's the favourite's price that is likely to be most under pressure."
