Carrus Mount Maunganui had to win three straight games in eight days to win the Williams Cup after coming from third place in the qualifying competition.
On Saturday they comprehensively defeated Element IMF Cadets in the 2015 Williams Cup grand final played at Bay of Plenty Cricket headquarters at the Bay Oval.
The Mount side took first use of the wicket and made a circumspect start to their innings.
However, a third wicket partnership between Ben Guild and Ben Musgrave produced 132 runs and put Mount Maunganui in the box seat. Guild was the first to depart after a solid 65, with Musgrave top scoring with a match winning 79 runs.
Cadets then upped their work in the field to effect two run outs and grab the last six wickets for 43 runs to dismiss Mount Maunganui for 265.
