Simmer took 5-39 as third-placed Academy cruised to a 160-run victory over a Berridge side that started the day second from bottom in the top-order.
In reply to Burridge’s 279-8 declared at the Ageas Bowl Nursery Ground, the hosts raced to 32-4 with White taking all four wickets.
His three victims – Charlie Mumford, Jude Wright and Andrew McEwan – failed to score, facing just seven balls between them.
Opener Wilf La Fontaine Jackson (25) watched all four depart before being fifth for 52, dismissed by Dan Stancliffe.
Academy reeled to 81-1 when Sullivan picked up his fifth victim, Sam Raffel.
It was the third time in his career that White had taken five wickets in the SPL’s top division, with his career best remaining 5-20 against Bashley six years ago.
But his latest five took his league tally to 28 – setting a new career best.
The extra points (29) ended up being the Academy’s highest score as they all went down to 119.
Skipper Joe Collings-Wells had earlier hit the highest score of 2022 – 76 – after winning the toss and electing to bat.
Azimunnor Chowdhury, who usually opens the game, came in at number 6 and also scored his best score of the campaign, 60. In the process, he shared the seventh wicket stand of 51 with Jack Watson (24).

Chowdhury also shared a fifth-wicket stand of 66 with Will Donald (38) as Burridge posted their highest score of the SPL season.
Bournemouth remain bottom despite an excellent three-wicket win over Bashley.
After being inserted at Chapel Gate, Bashley slumped to 29-7 (Dan Conway 5-16) before Finley Gordon (36) and George Wilson (31 not out) lifted the score to 103 all out.
Bournemouth’s reply was almost as poor as Bashley’s start – Dan Goody (6-25) starring as the home side slumped to 37-6 and 60-7.
At that stage in the game, 17 wickets fell for just 163 runs. But Jake Hurley and skipper Chris Park, batting at Nos. 8 and 9 respectively, put together a match-winning effort for the eighth wicket.
Hurley finished on 45 not out – with three fours and three sixes – and Park on 13 not out as Bournemouth reached their small target in the 28th over.
Goody’s tally was the third best in the top flight this season, ahead of only Josh Digby 7-21 (Bashley v Burridge) and Josh Krum 6-16 (South Wilts v Bournemouth).
