Leicestershire ensured they finished in the top half of Division Two with a 10-wicket win over Northamptonshire at Wantage Road in their season finale.
Off-spinner Naik finished with 4-58 and seamer Nathan Buck 3-89 as Northants were skittled for 198 in their second innings, having resumed at 10-1 on the final morning.
Only a ninth-wicket stand of 74 between James Middlebrook (62) and Lee Daggett (48) extended the game beyond early afternoon.
The Foxes were left to chase a target of just one, which Matthew Boyce (4) achieved by hitting the first ball from Alex Wakely (0-4) to the boundary.
Leicestershire finish in fourth place in the table, two places above Northamptonshire.
James Taylor hit his third County Championship century of the season on Wednesday as Leicestershire's batsmen dominated against Northamptonshire at Wantage Road.
The 20-year-old passed the 1,000-run mark for the season en route to a magnificent 156 off 316 balls as the visitors declared on 448 for nine.
Taylor started the day on 32 - his side 91 runs behind Northamptonshire - alongside Greg Smith, who could only add two more to his overnight total of 102 before David Burton toppled his leg stump.
Former England wicketkeeper Paul Nixon (65) put on 132 with Taylor before edging Jack Brooks' delivery to wicketkeeper David Murphy, while Tom New (43) shared a further stand of 68.
Taylor reached 150 off 308 balls before holing out to David Sales at short third man off Burton, who also claimed Jigar Naik (27), Nathan Buck (two) and Matthew Hoggard (nought) on his way to figures of five for 75.
The hosts, who made 250 in their first innings, reached 10 for one in their second when bad light ended play - stand-in captain Stephen Peters (four) trapped lbw by Buck in the second over.
Greg Smith's second century in a row allowed Leicestershire to reach 159-2 in reply to Northamptonshire's first innings of 250 before rain brought a premature end to the second day at Wantage Road.
Opening batsman Smith, fresh from a career-best 158 in last week's win over Gloucestershire, was unbeaten on exactly 100 when play was called off shortly after tea.
Smith added an unbroken 101 with James Taylor (32no) for the third wicket to leave the Foxes, who still have an outside chance of earning the second promotion spot in Division Two with a victory, 91 adrift of their hosts at the close.
Northants had earlier advanced from an overnight position of 186-6 to 250 all out, Leicestershire skipper Matthew Hoggard finishing with 5-48, his third five-wicket haul of the season.
Rob Newton's maiden first-class century helped Northamptonshire reach 186-6 in the 58 overs possible on the opening day against Leicestershire at Wantage Road.
The Foxes came into the final round of Division Two fixtures still harbouring faint promotion hopes - they require a victory, coupled with defeats for Glamorgan and Worcestershire to have any chance.
And they made a strong start, skipper Matthew Hoggard (3-39) taking two wickets with the new ball to help reduce Northants to 23-3 after opting to bat.
But stand-in skipper Stephen Peters (55), leading the hosts as Andrew Hall is injured, put on 99 either side of lunch with Newton to repair the damage.
And Newton, the 20-year-old Taunton-born right-hander, progressed to three figures for the first time after an early tea had been taken due to rain.
He reached the landmark from 111 deliveries, including 14 fours, before falling for 102 to left-arm spinner Claude Henderson (1-13), bad light ending play early shortly afterwards.
