Paterson claimed second spot and a psychological edge ahead of the finals over A-grade rivals Port Stephens 2nd XI.
In an even team performance, which will please skipper Russell Presland, Paterson dismissed the Pythons for 110 in 34.4 overs and made 4/112 in reply for a six-wicket win.
It was an important win just three rounds ahead of the finals and sets Paterson up for a home semi-final against the same opponent.
Matthew Jones had a terrific game with the ball claiming 3-6 from eight miserly overs, which included four maidens.
Rigby Vane-Wood continued his fine season with 2-24. Daniel Agland had his first bowl of the season and finished with 2-14 of 2.4 overs.
Agland earned man-of-the match honours with an unbeaten 48 to anchor the innings. It followed his 61 not out last week against Raworth.
Ramsey Vane-Wood made 28 and Chris Merchant chipped in with 14.
The win gives Paterson a two-point break on the ladder to Port Stephens 2nd XI, who are third on 50. Port’s 1st XI are top of the table with 54 points.
The Pythons firsts continued the top-three’s domination of the competition with a 10-wicket smashing of Lakeside Village Panthers.
Port sent the Panthers into bat and dismissed them for 37 in 18 overs. Port openers Tyran Eveleigh and Adam Butler both finished on 17 not out as they reached the target in 7.2 overs.
Paterson won by forfeit in C-grade against Fred Harvey Memorial.
