Worcestershire Under-19s will take a 124 run lead with two second innings wickets remaining into the final day of the three-day match with Northamptonshire Under-19s at Desborough.
Jujhar Johal picked up four wickets as the home side were bowled out for 277 – a lead of just 19 – as their last five wickets went down for 36 runs.
It was a fine fightback as Northants had stood on 124-1 at one stage in reply to Worcestershire's first innings total of 258.
But then Worcestershire ended the day on 143-8 with the top seven in the order all reaching double figures but no-one topping 30.
Northants had resumed this morning on 138-4 and reached 241-5.
Johal removed top scorer B. Claydon at that juncture for 76 off 134 balls with 15 boundaries and polished off the lower order.
He finished with 4-57 from 24.3 overs and Ryan Wheldon 3-81.
Callum Lea, who had scored an unbeaten 79 in the first innings, was promoted to open second time around.
He again top-scored with 28 but wickets fell at regular intervals.
