White Birch heads this nine-runner Class 1 contest at Windsor on good-to-firm ground narrowly ahead of Ghostwriter on a pound, and that slim but meaningful edge at the top of the ratings, combined with the good-to-firm ground and this twelve-furlong test, makes him the most compelling case in the field. Ghostwriter is the obvious threat and will not be easily shaken off, while Sea Scout and Tenability both carry identical figures and could make their presence felt if the principals disappoint. On balance, White Birch represents the strongest hand going into this contest and is taken to prevail.

Today: Tenability (draw 5) and Silawi (draw 6) get the bias; Warrant Holder (draw 9) is in the least-favoured band.
