Twenty wickets fell for only 151 runs at Chapel Gate, where Bournemouth bounced back from losing to champs BAT to nail ECB SEPL rivals South Wilts.
Bournemouth were dismissed for 99, but hit back to skittle South Wilts for 62.
Skipper Richard Scott ripped through the visitors' tail to finish with four wickets for just one run.
Portsmouth, meanwhile, made it two wins out of two with a narrow five-run victory over Liphook & Ripsley in a truncated affair on Southsea seafront.
Fordingbridge teenager James Manning was Portsmouth's hero with both bat and ball.
Panel umpires Roger Bowles and John Hardy were the two busiest men on the field at Chapel Gate, with nine leg before decisions being given.
But the two officials got it right every time. "The umpires had good games and the fact that so many batsmen were either bowled or trapped leg before was simply that the bowlers bowled wicket-to-wicket," explained Bournemouth's Martin Miller. "In total, there were eight bowled and nine leg befores. Just three batsmen fell to catches."
The respective sets of medium-pace bowlers excelled on the damp, green surface, with Bournemouth facing a second consecutive top-order collapse after Nick Park (21) and Scott had got them away to a 33-run start.
But, just as at BAT the previous week, Bournemouth's top order collapsed.
Hampshire left-armer James Tomlinson bowled Scott and then South African Alan Kruger nipped out Park and Miller with consecutive deliveries.
Worse was to follow, with Bournemouth lurching to 38-5 and 50-6 - the Kimberley debutant finishing his initial new-ball spell with three scalps.
Dan Jackson (22) and Nick Reeves (16) redressed the balance with a 39-run seventh-wicket partnership, which went some distance towards securing Bournemouth's eventual victory.
They raised the total to 89-7 before Adie Holewell (2-3) broke the stand and Kruger (4-27) and Tomlinson returned to mop up the tail at 99 all out.
With ex-Hampshire opener Jason Laney golfing in Portugal, South Wilts' batting looked brittle - and so it proved.
A disastrous start saw Wiltshire captain Russell Rowe trapped leg before by Tasmanian Rob Hodgson's first ball.
Jamie Glasson followed in identical fashion and minutes later Combined Services all-rounder Alex Senneck was castled by left-armer Martin Mixer to leave South Wilts tottering at 6-3.
South African-born Grant Mather (3-30) produced another effective spell of 'cutters' to breakthrough again after Rob Wade - making a comeback after last summer's bizarre collarbone break - begun to repair the damage.
Jo Cranch (24 not out) helped Kruger (15) lift South Wilts from 34-5 to 55 when Scott introduced himself to the attack.
The Bournemouth skipper bowled Kruger at 55-6 and then shot out John Chandler, Lysander Wolf and Tomlinson in quick succession as South Wilts lost their last five wickets for seven runs to plunge to 62 all out.
Liphook & Ripsley fell five runs short of a rain-adjusted target against revitalised Portsmouth in the gathering gloom.
Portsmouth had their 181-7 off 33 overs cut to 148, which Liphook had to chase in 27 overs.
Eastern Province opener Carl Bradfield made his Portsmouth debut but, unaccustomed to batting on soft surfaces, became a prize early victim for lanky teenager Matt Jones, who was making his Premier League debut.
The South African, who has scored over 4,500 first class runs in Provincial cricket, got an inside edge early on and departed for a disappointing three.
The Liphook seamers kept Portsmouth in check for some while and, after Ben Thane (29) departed, were in some difficulty at 82-5.
Thane fell to Nick Gay, whose 2-18 return also included the scalp of Lee Savident, a 121-run hero against the Hampshire Academy on day one.
Manning (49) added 59 in a key sixth-wicket stand with James Moon (22) and, at 179-7, was only denied his maiden Premier League half-century by a catch in the deep by Jeremy Bulled.
Weather interruptions left Liphook 27 overs to score 149 for victory - and while left-hander Graham Tyler was in, it appeared as though Portsmouth might come off second best.
Dominic Ridley, whom Liphook have signed from the University of Cape Town, played some elegant shots and will surely make sizeable scores when the strips firm up.
At 103-3, Liphook were well placed, but their threat subsided when Paul Ancell (4-31) and Manning, who capped a fine performance with a 3-23 return, sparked the fall of four wickets for just 13 runs.
But Liphook, chasing eight an over in the fading light, didn't give up the ghost.
Andy Brown (19) hit out - and was then run out - to leave Liphook needing 14 runs off Ancell's final over.
They got eight of them but lost their last two wickets and closed at 143 all out.
