The Bushrangers showed their intent early, looking to defend everything as the Warriors went went an all-out-attack mentality.
David Hussey (37no) absorbed 169 balls, while opener Rob Quiney (53) managed 163 balls before he edged to Sam Whiteman down leg side off the bowling of Andrew Tye (1-37).
Skipper Matthew's Wade's late cameo of 9 off 99 balls put the result to bed, as the Bushrangers held on with six wickets in hand.
