Star Cast
Confidence: Medium

Star Cast (SR 86, 9/2) carries the lightest weight in the field at 9-1, giving her a meaningful lbs edge over top-weight Model Yuko (SR 90, 10-4) and Quebella/Princess Rascal (10-2). Her form string of 631132 is the most consistently progressive in the race — three placings in her last four runs including back-to-back wins — and that sequence at the same class level is compelling evidence of a horse operating near peak form. Trainer Gemma Tutty is a sharp handler who places horses well, and the 9/2 price reflects market respect without the horse being over-bet. Good to Soft at 1m2f70y suits a horse whose form shows durability over a staying trip. Each-way alternative: Winged One. Main danger: Model Yuko — Model Yuko (SR 90, 10/3) is the highest-rated runner, the market leader, and Roger Varian's record with progressive fillies means the form figure '8-' last season can be discounted if she returns in better trim — she remains the one to beat on raw SR.
