Nottinghamshire 39 for 4 (Edwards 3-9) trail Hampshire 277 (Vince 74, Dawson 72, Abbott 60*) by 238 runs
Fidel Edwards produced a blistering evening six-over spell of 3 for 9 to complete an action-packed first day of Hampshire's Specsavers County Championship fixture with Nottinghamshire.
Nottinghamshire were forced to negotiate 15 evening overs having bowled Hampshire out for 277.
And Edwards, who now boasts 20 wickets against Nottinghamshire in five innings, blasted through fellow West Indian Kraigg Brathwaite, Jake Libby and nightwatchman Matt Milnes in an incredible fast bowling showcase.
Gareth Berg also managed to claim a scalp as the visitors struggled to 39 for 4, a deficit of 238.
Steven Mullaney found three wickets in five balls, before Luke Fletcher lead a spell of three wickets for the visitors without a run and then Matt Henry rounded off the innings with another flurry.
Mullaney elected to bowl without a toss but only managed to use the fast-bowling friendly conditions of heavy overcast clouds and floodlights to wrangle a single morning wicket.
Having seen play delayed by 45 minutes, Mark Footitt, on his first Championship appearance for Nottinghamshire since last August, found the outside of Weatherley's bat, with stand-in keeper Riki Wessels completing the catch.
It was two overs after lunch, though, when Nottinghamshire sparked Hampshire's first mini collapse with Mullaney's nagging top of off-stump length proving awkward to face.
Jimmy Adams, Sam Northeast and Tom Alsop will all compare notes of how Mullaney sneaked past their outside edges with just a hint of seam movement to clip the top of their bails. It meant Hampshire fell from 58 for 1 to 62 for 4 inside five Mullaney deliveries, over two overs.
Vince had watched the carnage unfold from the non-striker's end, unmoved with a steely stare after each team-mate moped back to the pavilion. The Hampshire captain sensibly, yet with plenty of aggression, dragged his side away from immediate danger by unfurling a series of off-side glorious shots.
Vince's recovery act saw him score 11 fours in a counter-attacking 74, his fifty coming from 68 balls. He had added 75 with Rilee Rossouw for the fifth wicket before a second crumple which saw Hampshire lose three wickets without scoring a run.
Rossouw was the first of the trio of scalps as he drove loosely to Matthew Carter at first slip off Luke Fletcher. Vince's rearguard ended when his attempted cut flicked up to Mullaney at first slip, who caught on the second juggle. Fletcher pinned Berg on the pads to complete the treble of wickets on 137.
But like the first flurry, a large partnership followed, this time between Dawson and Abbott. Dawson had only managed 101 runs in his first seven Championship innings of the summer, with a top score of 34 not out, but maturely batted his team out another sticky situation.
An innings built on hard running, with just five fours and a six, Dawson reached fifty in 69 deliveries. He fell for 72 when he charged down the wicket, swung his bat wildly, and was bowled by Carter.
Abbott had been the more watchful in the partnership but collected his own half-century in 95 balls. But Dawson's dismissal sparked another burst of wickets, with Steyn caught at first slip and Edwards run out by fellow West Indian Brathwaite - with Hampshire bowled out for 277.
Edwards got his revenge on Brathwaite in just the eighth over when Adams pulled off an impressive catch at second slip. Nash, who had two massive lbw appeals from Edwards turned down, was caught behind off Berg, before Edwards castled Libby and Milnes.
