Middlesex 156 for 3 (Malan 91*) beat Gloucestershire 168 for 8 (Hammond 42, Finn 3-18) by nine runs (DLS method)

Dawid Malan's imperious unbeaten knock of 91 steered Middlesex to a rare Vitality Blast victory against Gloucestershire at Radlett as they climbed to second place in the South Group.

Middlesex had registered only one win in their previous seven home T20 games against the West Country side - but always looked in control as they triumphed by seven wickets in the ground's inaugural Blast fixture.

The Seaxes' skipper entertained a sell-out crowd of 2227 as he flayed the Gloucestershire bowling to the tune of 91 from 59 deliveries, including seven fours and four sixes. At 156 for 3, Middlesex still needed 13 from 11 balls when a heavy downpour descended on the Cobden Hill ground - but their nine-run lead under the Duckworth-Lewis-Stern system was enough to secure the two points.

Gloucestershire opted to bat after winning the toss and Miles Hammond immediately went on the offensive, hitting Tom Helm for successive boundaries and sweeping Mujeeb Ur Rahman to register the first six of the match.

The left-hander dominated an opening stand of 53 with Michael Klinger, but Toby Roland-Jones and Steven Finn, bowling accurately in tandem, put the squeeze on Gloucestershire as they picked off three wickets for 20 runs. Roland-Jones made the breakthrough with one that kept low and uprooted Klinger's middle stump, while Finn found the outside edge of Ian Cockbain before having Hammond caught on the boundary.

Former Middlesex allrounder Ryan Higgins picked up the baton with 19 from 13 balls, including two maximums off Nathan Sowter - who had the last word by taking the catch to dismiss him when he skied Finn to deep midwicket.

James Bracey and Jack Taylor both holed out after threatening to dominate the closing stages, while a late flurry from Graeme van Buuren guided the visitors to a total of 168 for 8.

Gloucestershire needed wickets in the Powerplay to stand much chance of defending that total, but they failed to collect any as Malan and Paul Stirling quickly made inroads into the target.

Stirling displayed an effective mix of power and placement, punching two boundaries off Van Buuren's first over and swinging across the line to slam David Payne for an enormous six over long-on. The opener had made 33 from 26 balls when he speared Chris Liddle into the hands of deep extra cover - but his departure was no more than a fleeting setback for Middlesex.

Malan took a particular liking to the bowling of Tom Smith, dispatching the left-armer back over his head for the six that brought up his half-century from 30 balls and following that by sweeping and reverse sweeping the next two deliveries for four.

Stevie Eskinazi became Liddle's second victim as he miscued to cover and Eoin Morga also perished before the heavens suddenly opened to bring the game to a premature conclusion.
