Twiston-Davies looking forward to Rocky ride Sam Twiston-Davies believes there are more positives than negatives for Rocky Creek ahead of a second tilt at the Crabbie's Grand National at Aintree on Saturday. Unpenalised for an impressive success in the BetBright Chase at Kempton in February, the Paul Nicholls-trained nine-year-old attempts to improve upon last season's fifth-placed finish in the National. " I schooled him (on Monday morning), he was in great order and jumped 42 obstacles. He was very good, very fresh, and seems very well," his jockey told At The Races. "He ran round there last year and was very good. There's a lot of positives and not so many negatives." After leading the field at one stage in last year's National, Rocky Creek eventually faded, leaving a question mark hanging over his ability to stay the near four-and-a-half-mile trip. Twiston-Davies is banking on a National-focussed preparation yielding further improvement, saying: " When you look at him, obviously the one question is, 'Will he stay?' "He jumped the last in front last year, but he was almost trained for the Gold Cup, whereas this year he's been trained for the Grand National. "H opefully that gives him every chance."
