Northamptonshire took another giant step towards promotion from Division Two after crushing Glamorgan by an innings and 25 runs with a day to spare at Wantage Road.
The second-placed Steelbacks picked up a maximum haul of 24 points after bowling Glamorgan out for 241 and 187 having posted 417 in their only innings.
Starting day three with a 212-run deficit, Glamorgan lost Gareth Rees and Murray Goodwin before lunch, both to Australian seamer Trent Copeland.
Will Bragg and Chris Cooke added 70 for the third wicket but Azharullah (3-42) ended their stand when the former dragged on having made 44.
Cooke then went cheaply, having played well in making 42, when he gloved Azharullah's leg-side delivery to Northants wicketkeeper David Murphy.
It was now becoming a sorry procession for Glamorgan as their captain and wicketkeeper Mark Wallace (nine) was also taken by Murphy, this time off the bowling of Crook.
John Glover soon followed him back to the pavilion after making only a single and became the third wicket to fall in 12 balls when he edged Azharullah to Murphy.
The visitors slid ever closer to defeat when Andrew Salter (three) fell to Murphy's ninth catch of the match to give Andrew Hall his first wicket.
Dean Cosker (four) then smashed Copeland to Crook at fine leg to leave Northants on the brink of victory and maximum points.
Graham Wagg did give the hosts some resistance but he was to be left stranded on 34 as the result was wrapped up two overs before tea was due when Michael Reed (eight) was taken at first slip by Copeland off Hall.
