It was very hard not to be extremely impressed by Godolphin’s smart juvenile filly Certify who extended her unbeaten record to four as she slammed a classy field to easily land the Group 1 Shadwell Fillies’ Mile on day two of the Cambridgeshire fixture on the Rowley Mile at Newmarket.

The race that was formerly a staple of Ascot’s autumn fixture was moved to HQ last term, and Certify will clearly go down as an above-average winner of the contest regardless of previous high quality performances over the years.

The daughter of Elusive Quality, trained by Mahmood al Zarooni, came into the race on the back of three smart efforts, making a winning debut on the July course at Newmarket where she beat Pearl Sea by an easy three lengths, before returning to the same track to land the Group 3 German Thoroughbred Sweet Solera Stakes, where her length defeat of Sky Lantern was given a significant boost by the subsequent French Group 1 success of the runner-up.

Expected to win easily at Doncaster last month in the Group 2 Barrett Steel May Hill Stakes and duly sent off the 4/6 market leader in the horse racing betting offers, Certify was made to work very hard by the game Purr Along, eventually prevailing by a head after a protracted dual with William Muir’s talented filly.

After just a two week break the Mickael Barzalona-ridden two-year-old came back for more on the Rowley Mile at HQ and stepped up markedly on the already smart form she had shown by slaughtering a classy field in the Fillies’ Mile, to eventually come home an eased down four-and-a-half lengths clear of Roz.

What impressed most observers was the turn of foot that the Godolphin filly showed between the three and two furlong markers as she zoomed through from last to first to put the race to bed in a matter of strides, leaving her rivals gasping for air as she stormed away in the manner of a youngster who will surely prove hard to beat next term if she trains on.

Bookmakers, including bet365 racing betting, were quick to react to the win with most cutting Certify’s odds for next year’s Qipco 1000 Guineas from as big as 14/1 to a general offer of 8/1, although some firms go as short as 6/1.

Unlikely to be seen again this season, all roads will surely lead back to Newmarket next May for al Zarooni’s new star who, if making normal progression from two to three years, could prove very hard to beat in the first fillies’ classic of 2013.
