CARL Greenidge, son of former West Indies opening great Gordon Greenidge, helped make it a miserable night for Glamorgan at Bristol.

The 27-year-old dismissed top three Glamorgan batsmen Sourav Ganguly, Matthew Elliott and Ian Thomas at a personal cost of just 10 runs (he finished with 3-15), the latter pair in the space of three balls in a double wicket maiden.

That left Robert Croft's men in tatters at 33-3 off five overs in both side's second Twenty20 encounter and a succession of miserable shots left them on 123-9 at the end of their innings.

That was never enough even against a Gloucestershire side beaten in nine of their last ten games and whose previous win was in the county championship back on May 9 - against Glamorgan at Cardiff.

They eased to a seven-wickets win, their first in the competiton after conceding a record score last time against Northamptonshire, with 17 balls to spare at 132-3.

Openers Craig Spearman with 39 (30 balls, six fours) and Phil Weston with 31 (20 balls, five fours) sent them on their way with a stand of 59 in seven overs and though spinners Croft and Dean Cosker grabbed a few wickets, it was all too easy.

Afterwards Glamorgan skipper Croft said: "We must not be too down. We stuck to the task when it would have been easy to give in and this competition is a marathon, not a sprint. I'm sure five wins (out of eight) will get us through.

"We have to make sure we are up and at Warwickshire (at Swansea) on Saturday.

"We panicked a bit last night and did not really assess what a good total would be.

"We also have to try to work out our best batting order and how to make best use of our players and we'll maybe change a few things against Warwickshire."

That Glamorgan passed 100 and their previous lowest Twenty20 total of 113 against Warwickshire, at Edgbaston in 2003 was thanks to their skipper.

He cracked a six and four fours in an unbeaten 38 off 29 balls, and his last wicket stand of the same total with Dean Cosker (10 not) was the highest of the innings.

What had gone before them on a grey, drizzly night when barely 3,500 turned up, may have owed something to the conditions, but it was more a case of bad batting.

The ground had been under water in the morning after two heavy thunderstorms, but was in good condition for a prompt start.

Ganguly tamely holed out at point for a duck to the first ball he received, Elliot miscued very high to short-midwicket for 19 and Thomas missed with a heave for eight.

David Hemp was at least bowled by a decent yorker by Mark Hardinges, who also grabbed the wicket of Mike Powell, hero of Glamorgan's opening win against Somerset on Wednesday.

Mark Wallace, stumped, Darren Thomas, run out in a mix-up with Croft, and Alex Wharf, caught at deep mid wicket, hardly troubled the scorers but tailend pair Andrew Davies (11) and Cosker, with their captain, avoided complete disaster.

Also in Glamorgan and Gloucestershire's group, Northants beat Warwickshire by 39 runs last night.

Northamptonshire now lead the group with two wins from two games.
