Hopefully I am underestimating her Bustino, I just think she made hard enough work of the race at Newmarket and she has a bit to find with the top 2 on form based on that run, it wasnt a Taghrooda level performance when she won the same race before winning the Oaks. Enable showed more gears at Chester imo and obviously stays well so I dont think Horseplay can win on stamina alone.
I agree about the favourite, im not certain she will stay, certainly dont think she is a 1m4 filly anyway but her class could tell if she just about gets it.
