GLOUCESTERSHIRE opened their Royal London One-Day Cup campaign with a comprehensive eight-wicket win over Glamorgan at Sophia Gardens.

Chris Liddle and Danny Worrall laid the foundations with four and three wickets respectively as Glamorgan were all out for 264 after 49.3 overs.

George Hankins (85) and Chris Dent (80) put on 147 for Gloucestershire's opening wicket before Benny Howell's 68 not out eased his side to their 265-run victory target with 10 balls to spare.

It was no less than the 2015 winners deserved, with their bowlers sticking to their task, especially inside the final 10 overs when Glamorgan lost their final six wickets for 39 runs.

After electing to bat first, Glamorgan were forced to rebuild when they lost openers Jack Murphy (nine) and Nick Selman (32) inside the opening 12 overs.

Shaun Marsh and Colin Ingram (44) settled into a productive 98-run partnership before the latter, leading Glamorgan for the first time in his new role as one-day captain, pushed too early at Worrall's medium pace to give Howell at short cover a simple catch.

Marsh appeared set for a big innings but Worrall found some extra bounce and forced the Australian batsman to edge a lifting delivery to wicketkeeper Gareth Roderick to depart for 57.

Chris Cooke and David Lloyd then added a useful 75 for the fifth wicket but neither was able to kick on as Glamorgan's innings unravelled in the final eight overs.

Cooke's dismissal - bowled by Howell for 39 - started the collapse while Lloyd departed after making 45 when he found deep backward square leg off Liddle.

The lower order failed to make significant contributions and they were all out with three balls unused.

Gloucestershire's reply was ignited by back-to-back fours from Hankins, the 21-year-old making only his fourth List A appearance, in the third over as he and Dent made an excellent start.

Timm van der Gugten dropped a difficult caught and bowled chance to give Dent a life and the Gloucestershire captain was given another reprieve when a skier fell between fielders Cooke and Lloyd.

Dent was the first to his half-century from 51 balls, with Hankins reaching his landmark from another five balls, and such was their domination, that 15 fours were struck in the first 16 overs.

Graham Wagg - who, after bowling four overs of seam, reverted to spin in his fifth - made a belated breakthrough when Dent picked out Marchant de Lange at long-on.

With 39 needed, Hankins' excellent innings, a career-best effort in List A cricket, ended when he was leg before to Andrew Salter's off-spin.

Howell, who struck four fours and two sixes in his 81-ball innings, got Gloucestershire over the line in the penultimate over.
