Doyle's Choice: Diamond Necklace Poised to Command the Nassau

Doyle's public faith in Diamond Necklace has shifted this Nassau Stakes from a guessing game into a contest with a clear favourite. The mare arrives at Goodwood with a profile tailor-made for the undulating seven-furlong test and a jockey whose timing and judgement at this track are not academic—they are decisive.

Form, course and booking align; that is the simple arithmetic every punter pretends to miss. Diamond Necklace's recent pattern of late acceleration suits a race likely to be run at a solid tempo, and Doyle's ability to pick the dip and deliver a finishing kick turns potential into probability.

There are dangers: an enterprising pace or soft underfoot could reframe the race, and there are honest rivals who will not surrender ground willingly. Yet when you weigh pedigree, recent sectional times and the draw, the balance tips strongly towards the combination of horse and jockey rather than against them.

The Guru's call is unequivocal: back Diamond Necklace to win, and consider an each-way cover if odds lengthen past respectable value. For those who want more nuance, size your stake by market movement—if Doyle shortens further, you already know the script: he sees the line before the rest do.
