Both teams had a real dig. Both teams had the momentum at different points. Both had more than one opportunity to drop a goal, but Cas got it over eventually.
Some unusual decisions both ways - Willie Isa not binned for dangerous contact but Cook was with 10 to go, when losing a man hurts the most. Couple of Wigan tries chalked off but the reaction of the fans closest suggested they were.
Game could have gone either way at the end. Cas got lucky.
