BYRon Haycock rescued Waterlooville as the unbeaten Hampshire League division one leaders sneaked to a three-wicket win at St Cross Symondians.
The South African struck 89 in the triumph, which keeps his side on course for promotion.
Waterlooville captain Jon Hudson admitted it was a close-run thing, though.
‘We made life hard for ourselves and it was a pretty nervous changing room,’ said the skipper.
‘Thankfully Byron got us back in it after our terrible start chasing a target of 166 runs.
‘Three of our top four batsmen went for ducks and that’s never good.
‘It was a spicy wicket and the ball was fizzing around a bit.
‘In the end, Byron put on match-winning partnerships with Andrew Reynolds (16) and Sam Hillman (33 not out).’
Hillman was the pick of the bowlers taking three wickets as the home side batted first.
Twenty-year old Tom Southall also took his first two senior wickets as Waterlooville made it six wins from six.
Fareham & Crofton slumped to a disappointing 76-run home defeat against Easton & Martyr Worthy.
Portchester suffered an eight-wicket thumping in a rain affected contest at Hook & Newnham Basics.
