Chigumbura's four keeps Northants ahead
Glamorgan 207 trail Northamptonshire 494 by 287 runs
Zimbabwe international Elton Chigumbura took four wickets on his County Championship debut as Northamptonshire continued to dominate against Division Two leaders Glamorgan at Wantage Road.
Glamorgan captain Jamie Dalrymple took 4 for 71 as Northamptonshire were bowled out for 494 after lunch, losing their last five wickets for 42 runs, with their skipper Andrew Hall finishing unbeaten on 84. Chigumbura then claimed figures of 4 for 67 as the hosts' attack reduced the visitors to 207 all out, with David Lucas taking three wickets of his own.
Northamptonshire began the day on 355 for 5, with Chigumbura and Hall resuming on 5 and 6 respectively. Glamorgan's attack continued to toil, as they had on the first day, as the sixth-wicket pair dug their heels in, with Hall reaching a deserved half-century from 87 balls with a four through cover.
Dalrymple gave the visitors the breakthrough they desperately needed with the second ball after lunch when he forced Chigumbura (44) to play on to his own stumps to end a partnership of 108. The captain struck again in his next over, when wicketkeeper Mark Wallace caught an edge from his opposite number David Murphy, who faced ten balls without scoring.
Dean Cosker then trapped James Middlebrook (11) lbw before Lucas (8) sliced Dalrymple to Jim Allenby at slip. Dalrymple then claimed his fourth victim when he forced Jack Brooks, who failed to score off five balls, to edge to Wallace to leave Hall stranded on 84 not out.
Glamorgan's reply started disastrously when, in the first over, Mark Cosgrove went for a golden duck by edging Lucas to Murphy. It soon got worse when Tom Maynard (6) launched Brooks high in the air to Murphy, who took the catch at square leg, before Ben Wright (5) edged Lucas to the same man.
In the second over after tea, Dalrymple (8) drove at Lucas but Stephen Peters took a fantastic one-handed catch diving to his right at third slip. With the first ball of the next over Brooks pinned Gareth Rees lbw for 29 to leave Glamorgan floundering on 55 for 5.
Wallace made 21 before throwing his wicket away by lofting Chigumbura straight to Nicky Boje at midwicket. Chigumbura then took two wickets in consecutive balls in the 35th over when he caught Harris leg before then emphatically bowled Cosker, taking out his middle and off stumps.
He then struck again by bowling David Harrison (18) before Will Owen, who smashed 38 off 41 balls, sliced Boje to Murphy with the final ball of the day to leave Allenby on 59 not out.
