Jewel must dazzle to beat the stars in Underwood Class act: It's A Dundeel will take on Atlantic Jewel at Caulfield. Atlantic Jewel, the hot favourite for Saturday's group1 Underwood Stakes at Caulfield, will have to be every bit the potential great she is being hailed as if she is to take her unbeaten run to 10 with another top-level triumph. That's the only inference that can be drawn from a weights-and-measures appraisal of her rivals based on those announced this week by Victoria's chief handicapper Greg Carpenter, who frames the Melbourne Cup weights. Carpenter - acknowledged in the racing industry as a man who usually gets it right - has given Murray Baker's top-shelf New Zealand four-year-old It's A Dundeel 56 kilograms in the Melbourne Cup. That is the same weight he gave So You Think at the same stage of his career three years ago, even though the Bart Cummings-trained horse was by then already a Cox Plate winner. The implications are that in what was a very strong group of three-year-olds in the 2012-13 season, It's A Dundeel was right up there with the very best and, in Carpenter's view, considered at this stage to be the equal of such an outright champion in So You Think. That puts the scale of Atlantic Jewel's task into perspective, but also pays her an enormous compliment as she has beaten most of her key rivals already this season in the group 1 Memsie Stakes, her first race after 17 months out through injury. She will, of course, be expected to score again on Saturday over a distance - 1800 metres - that will be more in her favour than the likes of It's A Dundeel. Nevertheless, the highly rated New Zealander, who ran a good fourth to Atlantic Jewel on his reappearance in the 1400-metre Memsie, will get better as the distances increase. His main target is, like many in this field, the Cox Plate at Moonee Valley on October 26, so he is not fully wound up yet. But Baker is confident that he will give a good account on Saturday as he steps up in trip and fitness. "We are pretty happy with him, he's done everything right, but this race will help him," he said. We do see him as a 2000-metre to 2400-metre horse, so he will be running on at the end of this race. They certainly haven't missed him in the Cup weights, but he's a good judge, that Greg Carpenter. So is Baker. More than 20 years ago he brought high-quality galloper The Phantom to run in Australia, and after finishing third in the 1989 Caulfield Cup, he won the Memsie and Underwood in 1990 and was second behind Kingston Rule in the 1990 Melbourne Cup. Baker has also sent out the likes of Harris Tweed, who finished second in both the AJC Derby and the Caulfield Cup, Lion Tamer, who won the Victoria Derby, as well as Nom De Jeu, who took out an AJC Derby, so when it comes to knowing the standard required there are few better equipped to judge. "This horse is right up there with the best of them, I would say," is Baker's verdict on the winner of eight of 13 starts. It's A Dundeel swept through the Sydney autumn carnival and that is where his high ranking comes from, having won both the Rosehill Guineas and Australian Derby by six-length-plus margins. In the guineas he swept aside Sacred Falls, who at his very next start led home a trifecta of three-year-olds in one of the hardest races on the Australian calendar, the Doncaster Mile. The only blip on It's A Dundeel's radar has come when he ran in Melbourne as a three-year-old. He was beaten, as an odds-on favourite, by Super Cool at Moonee Valley in the Vase on Cox Plate day, and then he was an also-ran in the Victoria Derby behind Fiveandahalfstar and Super Cool. Baker says that his star doesn't have a problem with the Melbourne way of going, and his Memsie run, when he was a strong-finishing fourth, didn't suggest he had a problem with Caulfield. "You can't really say he has difficulty in Melbourne because he hasn't had that many starts here," he said. In the derby he got a long way back. It's A Dundeel is one of two Kiwi raiders in an Underwood Stakes that emphasises the international nature of the Australian spring these days, with gallopers that began their careers in England (My Quest For Peace, Green Moon and Sea Moon), France (Manighar, Puissance De Lune and Foreteller) and Germany (Waldpark) in the 14-strong field.
