After Triche missed a baseline layup against Dieng, Hancock stole Triche's ensuing inbounds pass and Hancock drained his fourth 3 off a slick pass to the corner from Smith to break the tie.
That paid off with a slick move that ended with James crossing at the corner in the 20th minute only for Robinson's conversion attempt rebounded off an upright.
Murphy followed up John Wilson's kick to the corner to complete his hat-trick, Mounis finished off a slick handling move, and Adam Mogg sent Greenshields sprinting 40 metres for his 18th try of the season.
