A career-best performance by Ben Sanderson - who took 7 for 22 from 13 overs on a pitch of variable bounce - enabled Northamptonshire to win their first Specsavers Championship game of the season as Glamorgan were bundled out for just 95 in 37.4 overs at the St. Helen's ground in Swansea.

Northants added a further 31 runs from 19 balls when play resumed, and after losing two wickets, declared with a lead of 346, with Timm van der Gugte ending with career-best figures of 5 for 61. Sean Terry, one of the batsmen dismissed, was clearly not happy with his decision when he was caught behind, and the former Hampshire batsman could well be reported for dissent.

Glamorgan made a disastrous start to their chase when Nick Selman, their first-innings centurion, was caught down the leg side from the second ball of the innings, and it soon became 2 for 2 when Will Bragg feathered one to the wicketkeeper.

Owen Morgan, who had been promoted to open after batting at No.9 in the first innings, was the next to go when he was bowled leg stump by Rory Kleinveldt, and when Jacques Rudolph drove to gully, Glamorgan had capitulated to 12 for 4.

Northants then began to spill their catches, with Aneurin Donald dropped three times from four balls, but after scoring 28, Donald showed his inexperience by attempting to heave a ball out of the ground eight balls before lunch, but only succeeded to give White a simple return catch. There was some resistance from Mark Wallace, but Sanderson polished off the tail, as Glamorgan suffered their second worst defeat in terms of runs against Northants since 1925.

Resuming at 56 for 5 after lunch, Glamorgan lost their last five wickets for 39 runs as Sanderson, bowling to a 7-2 field on the off-side, bowled an excellent line that had the batsmen continually playing and missing The 27-year-old Yorkshireman, who ironically had a trial with Glamorgan last season, completed a remarkable final spell by taking his last four wickets without conceding a run from 17 balls.

Had the Northants fielders not dropped five catches the home team would have been further embarrassed, and although they were without five first-team players, this was a poor batting performance with little application and technique.

Sanderson was understandably delighted with the team's win and his personal performance.

"At the start of the innings, there was little swing, but after working hard on the ball, it really was booming," he said. "We thought it would be hard work, but we also knew that if we hit proper lengths, we would be rewarded."

Asked about his post lunch spell Sanderson said: "The food is not great here, so I had a protein shake and it seemed to work!"
