Cadets were quickly in trouble, losing their first three wickets with less than 20 runs on the board.
Cadets middle order of skipper Scott Steward and Northern Knights Jono Boult toughed it out in the middle to get their side well and truly back in contention. Steward top scored with a solid 66 with Boult reaching 41.
