UK plunge up-ends Cox Plate market Trainer Jane Chapple-Hyam with Cox Plate contender Mull Of Killough. COX Plate wagering came to life with a longshot plunge on both sides of the world leading to the dramatic trimming of Mull Of Killough's odds with all fixed odds betting operators. The betting picture on the $3 million weight-for-age championship is one of neglect regarding the favourites. Punters are looking for value and the three-year-olds have joined Mull Of Killough as the firmers. As much as $101 has been on offer about the international entrant with a distinctly Australian connection but while Australia slept in the early hours of Friday morning, people on computers in Britain were having a tilt at the cricket score odds on offer. And all, apparently, because of a tipster on a website. Mull Of Killough's odds gradually tumbled from 50-1 to 20-1 with betting firm William Hill's clientele. Australian subsidiary Sportingbet, which offered as high as $81 when the field was announced on Tuesday, reported a series of bets on the largely unheralded eight-year-old gelding that rode the price down from $61 to $31. We arrived in the office to learn he would take out hundreds of thousands of dollars with a few bets alone. That sort of activity overnight is unusual," Sportingbet's Michael Felgate said. Odds have shortened across the corporate bookmaking fraternity, with $34 being the best on offer with fielders such as TAB Fixed Odds and Betstar. Mull Of Killough's trainer is Jane Chapple-Hyam, daughter of Andrew Peacock and Susan Renouf. An accomplished horsewoman based at Newmarket in England, she has campaigned this horse around the world and feels he has snuck under the radar. When she arrived, Chapple-Hyam said that if a horse with his credentials had come out to join an Australian trainer, he would never have been a 100-1 chance. Mull Of Killough reached Group III level, winning three races in succession at Newmarket between October last year and April this year, and began racking up his frequent flyer miles when he ran fifth in the Singapore International Cup in May at Kranji. He was back home for a second-placing at Ascot in July before taking off for Chicago, where he ran eighth on a track he found too firm in the Arlington Million. Chapple-Hyam took Mull Of Killough to Moonee Valley for a familiarisation gallop and vowed the turning but well-cambered circuit would not be used as an excuse if he runs below his best. Three-year-old Long John has thundered into contention for the 2040m test. After $15 could be snapped up a fortnight ago, the Caulfield Guineas winner is now into $7. He is seen as a horse that can race up on a moderate tempo and conserve energy for a frantic second half of the race. Shamus Award chased home Long John in the Caulfield Guineas, coming from the rear to run an eye-catching third. He is yet to win a race but has always competed against the highly-ranked members of his age group. Shamus Award is in from $81 to $21. It's A Dundeel, Puissance De Lune and Fiorente are drifting back towards the odds given when Atlantic Jewel was still in the field and held clear-cut favouritism. There has barely been a ripple for the Lloyd and Nick Williams-owned trio of Green Moon, Masked Marvel and Seville. Jockey Brett Prebble said Green Moon ($17) was the "forgotten horse," having failed to register a placing since winning the Melbourne Cup last year. Those with long memories are still emotionally scarred by Green Moon's appearance in last year's Cox Plate when he started favourite but finished seventh behind Ocean Park.
