Alex Hales inspired Nottinghamshire to a five-wicket victory over Worcestershire under the Duckworth-Lewis method as they maintained their 100 per cent Yorkshire Bank 40 record.
In a rain-shortened match at New Road, Hales impressed with the bat by making a quick-fire 72 from just 41 balls to make sure his side came away with their third win in the competition.
On a cool, murky afternoon all-rounder Gareth Andrew gave the home side what seemed to be a workable total of 132-5 in 16 overs thanks to a whirlwind innings, hitting eight fours and two sixes.
Moeen Ali got Worcestershire off to a blistering start with 28 in four overs but then made a tame exit when hoisting the Andy Carter's next delivery to Ed Cowan at wide mid-on.
But the home team only added a further 13 runs in the next five overs as Jake Ball and Samit Patel shared four wickets.
Worcestershire made the most of the remaining 30 balls, plundering 80 runs in all as Andrew roughed up Patel's figures with 19 in an over and then took 24 off the last over from Steven Mullaney.
Australian newcomer Michael Johnson chipped in 17 towards an unbroken partnership of 80 in 7.1 overs.
Nottinghamshire were then set a reduced target of 127 and despite losing Michael Lumb to a stunning catch by Thilan Samaraweera at short mid-wicket, Hales delivered exactly what the hosts wanted as he dipped into his repertoire as a Twenty20 international player.
He struck eight fours and two sixes before he was caught at point off Ali.
Riki Wessels (28) drove Brett D'Oliveira's first two deliveries, both full tosses, into the seating at long on before Jack Shantry claimed his second wicket.
There was just a hint of pressure when Daryl Mitchell bowled Samit Patel in a nagging spell of medium-pace but Nottinghamshire had four balls to spare when Steven Mullaney pulled Andrew for the winning boundary.
