Minster Could Start Favourite Sky Bet report a move for Rambling Minster to start favourite for the John Smith's Grand National. Keith Reveley's charge is 9s from 10/1 in outright betting with the firm - who has shortened in to 2/1 from 7/2 to be market leader when the tapes go up.. At the start of the week, all the momentum was behind My Will but he is now friendless after owner Andy Stewart said he was a 'silly price' as favourite earlier this week and has drifted right out from 4/5 to 2/1 to be favourite but Butler's Cabin remains a solid 6/5 shot. Matt Doyle of Sky Bet said: "It was a two-horse book at the start of the week on this popular market and a punt on Butler's Cabin gathered momentum when McCoy gave him the nod as his intended National mount. "However, there is always a story on National day and Rambling Minster is the horse the public have taken to their hearts with hard cash. He was well tipped up on TV this morning and could yet start favourite for the father and son team of Keith and James Reveley."
