Hampshire (4 pts) need 117 more runs to beat Notts (6 pts)
Title-chasing Nottinghamshire are closing in on an extraordinary victory against Hampshire on a day in which 19 wickets fell at Trent Bridge.
After the visitors were bowled out for 304 in their first innings before lunch, Hampshire, mired at the foot of the County Championship table and 73 behind on first innings, transformed the home side's 13 without loss to 47-6.
Eddie Jack, who turned 21 on Wednesday, swept aside the top three in 17 balls and 17-year-old Manny Lumsden, on debut, had two in his first seven.
After Scott Currie joined the wicket-taking, Lumsden, with pace and lift, then swept away three more in 13 balls to return 5-36 in 104 all out, leaving Hampshire to reach 178 for a third win of the summer.
Roused, Notts reduced them to 11-4 when Jake Lehmann went for two after his unbeaten 133 earlier. It became 27-6 when two fell on the same score. By the time bad light halted frantic proceedings at 17:00 BST, the unbroken seventh-wicket had lowered the target to 117 more runs required with four wickets in hand.
There was more life than on Wednesday in a pitch that had perhaps started to crack and both Olly Stone and Dillon Pennington claimed three wickets in seven-over new-ball spells.
Felix Organ top-edged a swipe to be held at a tantalising second attempt at mid-on by Pennington who then had Nick Gubbins and Toby Albert in three overs.
Albert, driving, was outstandingly taken low down at backward point by Sam Seecharan, a substitute fielder, on a day when no chances escaped amid the high tension. Lehmann, cutting and top-edging, followed as Stone reprised the bowling that brought him 10-94 in Nottinghamshire's last win, against Surrey three matches ago.
When Nottinghamshire had batted again 35 minutes from lunch they might have turned thoughts to when their declaration might follow and how generous a target they could risk.
Haseeb Hameed had in fact soon gloved the muscular Jack behind for five and Freddie McCann miscued him to third man for four as the carnage commenced.
Six balls after the interval, Jack hit the top of Ben Slater's off stump and after 22 runs had doubled the score, Lumsden produced the superb balls of speed and sharp bounce that did for Jack Haynes and Mitchell Hay, as captain Ben Brown moved further towards 10 catches in the match.
Currie removed Liam Patterson-White from a top-edged pull and, after 28 had come in a counter-attacking six overs, he starightened one to bowl Fraser Sheat for 16. Lumsden removed Olly Stone to make it 88-8.
Not so for Nottinghamshire. Four overs later, after Joe Clarke, for 37, and Pennington had both gone to fine running catches trying to take on Lumsden, they were all out at an early tea.
Notts had earlier grasped their third and final bowling point with 16 balls to spare after Hampshire resumed their first innings on 267-7 with 10 bonus-point overs remaining. Hampshire, their last pair together, were nine runs short of a second batting point at the cut-off point before finishing on 304.
Should they win, the bonus-point element could yet be critical for Notts, four behind leaders Somerset, but would look academic for Hampshire if they lose. They would need to close a 32-point gap to avoid relegation.
