Castletown Keys has made it back-to-back wins this campaign with victory in the feature event at Northam on Sunday: the $50,000 Gannon’s Ladies Day Cup.

The Dan Morton-trained 4-year-old proved too strong for Thundelarra and Fine Memories with Demelza’s Wings in fourth position.

Despite being a touch slow out of the gates and being settled behind early she displayed far too much finishing power over the concluding stages to maintain her recent good form.

Thundelarra loomed a fleeting chance on the outside and was also finishing powerfully while Fine Memories fell in for third after leading them in.

The win takes Castletown Keys record to three wins and three placings from 8 career starts with the promise of future wins in store.

She hasn't missed the money at her past six runs.
