Worcestershire Seconds completed their second successive innings victory after bowling out Northamptonshire Seconds twice in a day at Kidderminster.
The county followed up their innings win over Middlesex at Radlett last week by triumphing by an innings and 63 runs.
Worcestershire had been bowled out for 386 on the opening day and dismissed Northants for 178 and, following on, 145, to win the three-day match at Chester Road with a day to spare.
Ross Whiteley and triallist Ben Sanderson picked up three wickets apiece in Northants first innings and then Chris Russell, who last week signed a new two year contract with Worcestershire, returned figures of 5-61 in their second innings.
Northants reached 63-1 in their first innings after a stand of 57 between Zaakir Khawaja and Harry Evans but then lost four wickets at that total.
The only other resistance came from Vicram Sohal and Saif Zaid, who made 54 off 91 balls with 10 fours, in a seventh wicket partnership of 59.
Worcestershire skipper Matt Pardoe enforced the follow on and this time Russell did the early damage as Northants were reduced to 37-4.
Olly Stone (41) and Zaid, who was run out by Brett D'Oliveira's throw from backward square leg, added 53 for the fifth wicket but Northants were bowled out in just 36.3 overs.
Worcestershire end their Seconds campaign with a three-day fixture against Hampshire at New Road starting on Monday September 1.
