Fer me it is one of life's mysteries, Ruby seemed to have the horse in stride and took her to the front at the correct time and was straight on fer the final hurdle, he could have held her back or got in to trouble within the field but he didn't.
Realistically the figure won or lost on Annie Power was in the Billions if you take all the online betting in to account.
Why would he ride such a great race on the horse and then Pull her at the final hurdle ?
I reckon Ruby will take the truth to the grave with him !
