Will Steward praised his bowlers as Burridge beat Havant by 37 runs in the Southern League premier division on Saturday.
It didn't look good for the home side after they were bowled out for 166 – with Richard Jerry (three for 28) and Graham Burns (four for 28) doing the damage for Havant.
Overseas player Hilio De Abreu (47) along with James Richards (23) and Azimunoor Chowdhury (28) helped Burridge get to a total they had a chance of defending.
And when Havant replied, only Richard Hindley (36) and Chris Morgan (30) showed any resilience.
Richard Lock (four for 18) and Sullivan White (three for 18) applied the pressure.
Steward said: ‘We didn’t bat very well. Luckily this season if one aspect of our game hasn’t performed the other has.
‘Sullivan White set up the win with three very good early wickets.
‘This put Havant on the back foot and Rich Lock finished the job with his off-spin.
‘We kept it tight all the way through and refused to let Havant get away.’
Burridge remain in second place ahead of the last game.
But they need leaders St Cross to slip up badly if they are to snatch the title away.
‘We are still in with a slim chance and will keep going right to the end,’ added Steward.
‘It is St Cross’s title to lose. But we believe we have wrapped up the one-day pennant.
‘We have stayed in the hunt for the title right through the summer.
‘It has been a terrific season and we have missed out only by small margins.’
Portsmouth slipped to fourth in division one after they were bowled out of 127 in a six-wicket defeat at OTs & Romsey.
Sarisbury Athletic remain second despite a disappointing seven-wicket reverse at Andover.
The visitors collapsed to 184 all out wasting an opening partnership of 102 between Sam Floyd (51) and Colin Day (37).
In division two, Waterlooville claimed a four-run win against Tichborne Park.
Max Goddard scored 29 and took four for 21.
