Glamorgan won a rain-affected Twenty20 Cup clash against Northamptonshire at Cardiff by 10 runs..
In a 17-over contest Glamorgan, who won the toss, made 154 for six with the visitors needing to make 158 for nine under the Duckworth-Lewis method.
They reached 147 for nine, failing to get the 23 needed off the final over.
It is Northamptonshire's second consecutive defeat after they won their opening four matches while Glamorgan's victory keeps them in the mix for a quarter-final place.
After play began 10 minutes later than scheduled at 7.10pm because of rain the Glamorgan openers, Robert Croft and David Hemp, made a positive start against Northamptonshire's South African seam contingent of Johannes van der Wath, Johann Louw, Lance Klusener and Andrew Hall.
Hemp and Croft raced to 53 without loss in 30 balls before the former was bowled by Hall.
Croft continued to take the attacking option hitting, both spinners - Jason Brown and Monty Panesar - for straight sixes before he was bowled by the England slow left-armer for 46 from 29 balls - 36 coming in boundaries.
The momentum was kept up by Herschelle Gibbs and Michael Powell, who was particularly effective flicking both Panesar and Louw over their heads for four.
But as the steady rain continued umpires Peter Willey and Steve Garrett took the players off the field at 7.55pm with Glamorgan 106 for two after 12 overs.
When play resumed at 9.10 Gibbs, 42 from 32 balls, and Powell helped Glamorgan up to 154 for six in their 17 overs.
Rob White got the Steelbacks' reply off to a confident start with two sixes in the opening two overs before fellow opener Klusener chopped David Harrison onto his stumps.
Hall was bowled by Alex Wharf as Northamptonshire were reduced to 35 for two in the fourth over.
After White struck Dean Cosker for a third six he lost David Sales caught at short midwicket off Croft.
Northamptonshire lost too many wickets at regular intervals and when Niall O'Brien was bowled in the final over Glamorgan were home and dry.
