At 126 for six, Bay of Plenty were in several degrees of trouble which got worse when they were just 146 with the last two Bay of Plenty batsmen at the wicket. Campbell Thomas and Gurwinder Singh put on 36 runs for the tenth wicket as Bay of Plenty were bowled out for 181.
Singh in his first year out of Tauranga Boys' College fought hard to post an unbeaten 25 runs.
Hawke's Bay bowlers Christian Leopard and GC Pretorius did the damage with the ball, with Leopard grabbing four wickets while Pretorius took three wickets for 32 runs.
The overs were slightly reduced due to a mid-afternoon rain delay with the home side bowlers making an early impact. A fighting knock of 36 not out from Christian Leopard got Hawke's Bay over the line with two wickets in hand.
Boult was the best of the Bay of Plenty bowlers with four wickets, with Singh and Hampton picking up two wickets.
Hawkes Bay batted first in game two and set the home side a solid target, when they reached 226 for the loss of nine wickets, in their allotted 50 overs.
Indika Senarthne (49), Bradley Schmulian( 42) and Christian Leopard (35) all made solid contributions to the visitors total. The Bay of Plenty wickets were shared around with Brody Gilroy, Peter Drysdale and Hampton taking two bowling scalps.
Hawke's Bay bowled grabbed the early ascendancy and had Bay of Plenty in serious trouble at five down with just 80 runs on the board. The two Northern Knights players dug deep with Hampton top scoring with a fighting knock of 88 and Boult posting 45.
"The fight-back from Hammer and Jono not only took us a long way to victory but gave the two ND boys plenty of time in the middle early in the season," Williams said.
Determined defence by the tailenders saw Bay of Plenty get home for victory with a one wicket to spare.
