Centennial Park trainer David Payne will be hoping his horse continues his winning momentum. CENTENNIAL Park's owners had to wait two years for their sprinter to win another race. They may only need to wait three weeks this time. At Rosehill Gardens today, Centennial Park will be out to continue his winning in the Group 2 $175,000 Ajax Stakes (1500m). Trainer David Payne said the rising eight-year-old has renewed confidence after he scored in the Super Saturday Stakes at Flemington earlier this month."Winning that race has done the horse the world of good," Payne said. It had been a long time since he had won a race and you start to think whether he will ever win again? But he has been racing well without winning over those two years and against some very good horses. He's really going well and I think he will be hard to beat again. I'd love to see him win because he needs about $50,000 prizemoney to break the $1 million in career earnings. Payne said Centennial Park's longevity and quiet nature has made him a stable favourite. "He's the most sweet-natured horse," the trainer continued. He's a 'gentleman' and all the kids who come here learn to ride on him including (star apprentice) Chad Schofield. I know he has drawn off the track (barrier 16) but they should run along in this race and if (jockey) Michael (Rodd) can find some cover, then he will be competitive. The Ajax Stakes also features the Australian debut of the former outstanding English galloper Carlton House, owned by Her Majesty Queen Elizabeth II. Carlton House, now trained by Gai Waterhouse, is Group 1 placed in the 2011 English Derby (third), then last year when he ran second in the Prince of Wales's Stakes behind Aussie superstar So You Think. He brings those world-class formlines to Rosehill Gardens - and the Queen's famous racing colours of purple with gold braid, scarlet sleeves, black velvet cap and gold fringe. With Waterhouse's stable rider Nash Rawiller sidelined through suspension, Hugh Bowman has been selected to ride Carlton House. "I just felt Hugh was successful enough in England and he understands the different conditions these European horses face when they come to Australia," Waterhouse explained. Peter Moody, trainer of Black Caviar, may not need the mighty mare to win another Group 1 sprint as he believes Golden Archer will prove to beat in the $350,000 The Galaxy (1100m). "This has been his target race all along and even though he finished well back at Warwick Farm the other day there were excuses," Moody said. We rode him back from an outside barrier and it didn't suit him at all. The barrier here is the key, and he's drawn a good one.
