Not sure about the rain but Isaiah looks tough from this side of the ditch. Does tend to over race in the field so when the big money is up they tend to send him. Brilliant win at Auckland in December over 2200, blasting the gate and ran them off their feet with Maxim and Sky Major unable to get close. Drawn well so would expect him to lead and be hard to run down. Not sure what effect the wet track will play as the inside does seem off at Menangle when it rains.
