Nostrum rates 3 lb below the top-rated Rocking Ends on these figures, but a progressive profile makes a compelling case that the gap in current form is considerably narrower than the bare ratings suggest, and on good ground over six furlongs at Newmarket there is every reason to expect further improvement. Rocking Ends is the most obvious threat given that rating advantage, while Expert Agent and Rajaking also enter calculations and must not be dismissed lightly. The selection is taken to edge out the top-rated on the strength of an upward trajectory that the others may struggle to match. Nostrum is our selection.
