DURHAM Cricket Board had no intention of going quietly.

Lord's may have decreed that this would be their last hurrah in the Cheltenham and Gloucester Trophy, but Durham went out with a bang rather than a whimper.

After chasing leather around Feethams during Glamorgan's innings, former England Under-19 man Philip Mustard took apart Australia pace bowler Michael Kasprowicz.

And once the aggressive Mustard had fallen on his dashing blade for 33 from as many balls, Chester-le-Street's Alan Worthy struck an attractive 59.

Australian Marcus North, a professional at Gateshead Fell, added a fighting 46 as Durham lost their last six wickets for 48 runs to be bowled out for 226.

Realistically, Durham were never going to cause an upset, even when Mustard - who made 75 on his first-class debut against Sri Lanka last year - was cutting loose.

But Kasprowicz in particular was left licking his wounds as the National League champions returned to Cardiff last night.

He was withdrawn from the attack by captain Robert Croft after his first five overs went for 42 runs.

Mustard got off the mark by slapping Kasprowicz over mid-on for six; the 20-year-old then hit three fours in another over from the Queenslander.

It was too good to last, however, and left-hander Mustard's belligerent knock, which contained two sixes and four fours, ended when he gave a steepling catch off Croft to Kasprowicz at mid-off.

Glamorgan moved into the fourth round with an 86-run victory, exposing the chasm in class between the teams.

But at least the Durham Cricket Board, in their valedictory C&G Trophy appearance due to cutbacks in the ECB budget, went down fighting.

Mustard said: "I know Kasprowicz is a class bowler, but I was happy playing my shots at him. If the ball was there to hit, I was going to hit it.

"I've played in friendlies against Durham University and for my club, but playing against the likes of Glamorgan is great experience for me. This year, I want to play a few first-team games. It would be a massive break to get in the first team, but I've just got to be patient."

Glamorgan paid Durham the ultimate compliment by fielding the strongest side available to Croft.

And there was the briefest of suggestions that Durham - denied the services of the injured Quentin Hughes, Gary Scott and Ashley Day - would run the visitors close.

Mustard and Worthy led the North-Easterners to 68 for one off nine overs before Croft applied the brakes. Worthy fell when he mistimed a drive off Adrian Dale's medium pace and skied a catch to Michael Powell at mid-off.

Dale then accounted for Karl Coetzer (30) in his next over, and Durham's effort subsequently petered out as Glamorgan squeezed the life out of their innings.

Earlier, Matthew Maynard made a century on the same Darlington ground where, 12 years ago, he hit 151 not out against Durham when they were still a Minor County.

Maynard smashed his fifth ton of a golden 2003 to form the bedrock of Glamorgan's total of 312 for nine. He struck 115 off just 86 balls and despatched Durham's attack to all parts of Feethams before hoisting Ian Hunter to deep square leg.

The hosts were left to rue dropping Maynard twice as the 37-year-old former England batsman continued to enjoy the Indian Summer to his career.

Opener Ian Thomas compiled 93 as he put on 135 in 19 overs with Maynard, and but for a late flurry of wickets Glamorgan would have compiled an even more imposing score.
