GLAMORGAN head into their last floodlit game of the season at Sophia Gardens tonight knowing the difference between winning and losing their NatWest Pro40 League clash against Northamptonshire could be dramatic.

Defeat could mean Glamorgan are dragged into a dogfight towards the bottom, while victory against Northants, and Lancashire on Sunday week, could give the Welsh county the outside possibility of finishing top.

''It's turning into quite a competition and you just can't relax, which can only be a good thing,'' said Glamorgan's director of cricket John Derrick.

''There does not seem a happy medium, you are either looking above or below you.

''I was quite happy to see Northants have their game against Lancashire rained off on Sunday, even though it meant they went above us because they have more wins.

''It should be a good game under the lights and we are always confident we can do well at home.''

Glamorgan give a recall to left-hander Dan Cherry as a replacement for Mark Cosgrove, who returned home at the weekend because of international commitments.

Cherry is the only change in the lineup from the side which beat Nottinghamshire by five wickets at Trent Bridge at the end of last month.

But it is likely that skipper Robert Croft will open with Richard Grant.

Glamorgan Dragons: R Croft (capt), R Grant, M Powell, D Hemp, J Franklin, R Watkins, D Cherry, M Wallace, D Harrison, A Davies, D Cosker.
