A new protagonist in the twisting, turning narrative of the 2012 Patinack Farm Blue Diamond Stakes was revealed today as Mama’s Choice stormed to victory in the Listed $100,000 Emirates Airline (née Chairman’s) Stakes at Caulfield.

The most impressive last-to-first victory, under four-time Blue Diamond-winning hoop Dwayne Dunn, created further disarray in betting for February 25’s Patinack Farm Blue Diamond Stakes as another nominal favourite, this time Jimando, was deposed.

Mama’s Choice – one of eight David Hayes-trained youngsters among Wednesday’s third declarations – is now a $9.50 sixth-elect in Sportingbet Australia’s Diamond market, led by Australia Day’s impressive Patinack Farm Blue Diamond Preview winner, Malasun ($6).

The Emirates Airline Stakes was the first of four Stakes-level races on Shadwell Stud Australasia Race Day, included imposing fresh wins from returning stars Mosheen and Bel Sprinter.

Mosheen was sent out a warm favourite in the Listed $100,000 Shadwell Stud Australasia (Manfred) Stakes and coasted to victory with the class she exhibited abundantly in the spring.

The thunder of Bel Sprinter’s dominant hooves in the Listed $100,000 United Arab Emirates (W.J. Adams) Stakes was matched only by the excited hoots and hollers of a delighted gaggle of owners, who now look forward to their first attempt at the highest level in the $400,000 Group 1 Sportingbet Oakleigh Plate at Caulfield on February 25.

The smorgasbord of black-type racing was rounded out with the Listed $100,000 Reaan Plate – formerly the Victoria Gold Cup and now also considered the Prelude to the $300,000 Centrebet Mornington Cup on February 15 – which was taken out by Bolton.

The theme of Shadwell Stud Australasia Race Day was a fusion of Australian and Arabian, with United Arab Emirates Ambassador to Australia, His Excellency Ali Nasser Al Nuaimi, and Minister for Racing, Dr Denis Napthine, among those celebrating at Caulfield.

The day began with the running of the Shadwell Arabian Mile, for pure-bred Arabian horses, which was taken out by Warrawee Naaziq.

Racing returns to Caulfield in a week’s time with Caulfield Festival Family Day, featuring Black Caviar’s attempt at 18 consecutive victories from debut in the $402,000 Group 1 Sportingbet C.F. Orr Stakes, at which the public will be admitted free of charge.
