Cassidy blown away by Pierro's might and power Rain dance: Jim Cassidy drives Pierro to victory. Jim Cassidy boldly declared superstar colt Pierro the best horse he's ridden, better than Might And Power, after the three-year-old dashed to victory in the Canterbury Stakes on Saturday. Warming the seat for Nash Rawiller, who opted to honour a previous booking on mighty mare More Joyous ($4), Cassidy drove Pierro ($2 favourite) to victory and recorded the 97th group 1 win of his career. And then came the inevitable comparison with the 50-year-old's 1997 Melbourne Cup winner Might And Power. "I put this bloke above him at this stage," Cassidy said. To do what he did as a two-year-old and to do what he did as a three-year-old, win the Hobartville first-up and come back to 1300 [metres] and win the way he won today [is incredible]. I don't like using the word freaky but to do what he's done and come back and take on the older horses, the sky's the limit with him. Including a potential clash with his Caulfield Guineas and Cox Plate conqueror All Too Hard. "Bring on All Too Hard, bring on whoever you like ... he'll deal with them," Cassidy said. I've been lucky enough to ride some good ones and I was very privileged and very honoured to ride this great colt [on Saturday]. Pierro stalked the early speed of Rain Affair and Moment Of Change, surging to the lead at the 200-metre mark and coasting to his fourth group 1 win. More Joyous chased valiantly in second, three-quarters of a length away, and lost no admirers despite suffering her first loss in the Sydney autumn since the 2011 Doncaster Handicap. Robert Heathcote's Solzhenitsyn rattled home for third. Only last spring's Caulfield Guineas and Cox Plate blot Pierro's copybook, which stands at 10 wins from 12 starts. Owner Greg Kolivos, who races the Lonhro colt with wife Donna, admitted it was a big risk to take on More Joyous and a bevy of other group 1 winners. "We've got a great horse, he's a superstar," Kolivos said.
