Hampshire 367 (Vince 95, Dawson 63, White 4-80) beat Northamptonshire 56 (Barker 4-13) and 176 (Zaib 57*, Whiteman 45, Dawson 6-61) by an innings and 135 runs

Dawson claimed 6 for 61 for his sixth first-class five-for and his best figures at the Ageas Bowl to reignite Hampshire's title hopes after two winless matches with victory by an innings and 135 runs coming inside three days.

Northamptonshire, who have one win and a solitary batting bonus point so far this season, only claimed three points from the match as they sit rock bottom of Division One.

Hampshire have dominated Northamptonshire in their three Championship clashes - starting at the Ageas Bowl last September and continuing in home and away drubbings this term.

Their three innings have resulted in 1,249 runs - in response, Northamptonshire have only cobbled together 840 in six innings. This thrashing was fashioned on the first two days.

Northamptonshire were bowled out for a new Ageas Bowl low of 56 in 30.2 overs and were already two down in their second innings by the close.

Their head coach John Sadler called for "fight, graft and resilience" and promoted the idea of classic red ball batting going forward. Sam Whiteman and Rob Keogh took that to heart. The duo batted out 39 of the first 42 balls of the day as dots and took few risks, while starting to nibble away at the deficit.

Whiteman would face 93 balls and Keogh 113, but after an hour of occupation under stunning blue skies, a collapse wasn't far away.

Dawson's second over of the day was long enough to see Australian Whiteman attempt a drive out of the rough, only to get bowled through the gate.

Ricardo Vasconcelos also took the attacking route out but missed his slog sweep by a distance to leave his stumps exposed.

Keogh had been dropped earlier in the morning by Dawson before the left-arm spinner had him leg before with an arm ball and Northamptonshire were now 150 for 5, having been 89 for 2 little more than 10 overs earlier.

Mohammad Abbas had James Sales lbw with the first ball after lunch to begin a post-interval collapse of 33 for 5.

Dawson returned to pin Tom Taylor in front for a pair - joining Hassan Azad in the scoreless corner - before Jordan Buckingham went back to another one which went on with the arm.

But Dawson kissed the top of Jack White's off stump with a ragging delivery and Mason Crane - on his first appearance of the season - got Alex Russell to edge to first slip to end Northamptonshire's miserable trip to the south coast at 2:40pm. The last eight wickets had been lost for just 87 runs.
