Matt Coles claimed career-best figures of 6-51 as Kent powered to an innings-and-120-run victory over Northamptonshire early on day three.
The Kent all-rounder took four of the remaining six Northants wickets to ensure the visiting Spitfires recorded their first LV= County Championship Division Two victory of the season with five sessions to spare.
Resuming on 50-4, still 186 runs away from making Kent bat again, Northants lost their remaining hope of salvaging a result when captain David Sales (42) was bowled by Coles in the ninth over of the day.
The 21-year-old medium-pacer added the wickets of David Willey, Jack Brooks and Lee Daggett - all caught behind the wicket - as Northants crashed to back-to-back defeats.
Nial O'Brien was left unbeaten on a painfully slow 25 from 115 balls as the home side picked up just two points from the fixture, with dominant Kent coming away with 23.
Mike Powell hit an unbeaten 128 as Kent took control of their Division Two clash against Northampton at Wantage Road.
The 35-year-old veteran hit 19 fours off 227 deliveries, as the visitors posted a challenging 368 in their first innings.
Powell was ably assisted by wicket-keeper Geraint Jones whose patient 53 came off 144 balls, with the pair putting on a vital 165 for the seventh wicket.
The partnership enabled the visitors to the County Ground to collect a first-innings lead of 236.
Northants, in their second innings, were reduced to 50-4 by stumps, still needing another 186 runs to make Kent bat again.
Home hopes appear to depend on David Sales who is 31 not out - off 34 - but on Saturday they are likely to slip to their second County Championship defeat of the season.
Kent finished an eventful opening day at Wantage Road on 127-3 after dismissing hosts Northamptonshire for just 132.
Charlie Shreck, Matt Coles and Darren Stevens each claimed three wickets apiece to leave home skipper David Sales, standing in for the absent Andrew Hall, regretting his decision to bat first after winning the toss.
It was actually Mark Davies who struck the first blow for Kent, removing opener Rob Newton for just seven when he edged to James Tredwell.
Kent's seamers simply never let up after the early breakthrough, the only real resistance coming from Alex Wakely (33) and David Willey, who made a breezy 24 before being the last man out.
In reply, the visitors lost skipper Rob Key for seven and Scott Newman followed for 26 when he slashed Jack Brooks to James Middlebrook at gully.
Ben Harmison reached 46 off just 64 balls, including seven fours, before he was run out by Willey's direct hit at the stumps from point, ending an 83-run stand with Brendan Nash (40 not out).
