Will Porterfield returned from international duty with Ireland to lead Gloucestershire to a 128-run Friends Provident Trophy win over Surrey at Bristol.

Fresh from captaining his country to qualification for the 2011 World Cup, Porterfield hit 74 in a total of 268 for nine after Surrey had won the toss. Chris Taylor made 63, while Andre Nel was the pick of the visiting attack with three for 39 from his 10 overs.

In reply, the Brown Caps could manage only 140 all out in a poor batting effort, Usman Afzaal top scoring with 36. Ian Saxelby claimed four for 31, Alex Gidman two for 29 and Vikram Banerjee two for 34.

Porterfield, in the Gloucestershire CCC side for the first time this season after leading Ireland in South Africa, hit his runs off 84 balls, with eight fours, after openers Kadeer Ali and Hamish Marshall had fallen cheaply.

Skipper Gidman made 31 in a third-wicket stand of 96 with Porterfield before Taylor took charge, timing the ball sweetly in making his 63 off 58 deliveries, with seven boundaries.

Batting was not easy early on as the ball seamed around under cloudy skies. But from 29 for two Gloucestershire fought back well to set a testing target.

Jon Lewis (32) helped Taylor add 60 for the seventh wicket as the home side scored 36 runs from their five-over batting power play, taken at the start of the 41st over.

Surrey progressed to 25 without loss before James Benning cut Saxelby to Taylor at backward point. It was 37 for one after 10 overs and Gloucestershire immediately took their bowling power play.

The five overs saw Surrey score only 14 runs for the loss of skipper Michael Brown, caught at mid-on miscuing a delivery from Saxelby, and Mark Ramprakash, whose first domestic innings of the season lasted only five balls before he was caught behind off Steve Kirby for a duck.

Banerjee was then introduced into the attack and the left-arm spinner varied his pace and flight well.

Jonathan Batty was run out by Kirby attempting a swept single off Banerjee before Taylor removed Grant Elliott with a superb one-handed catch at full stretch above his head at backward point off Gidman.

Chris Jordan was lbw playing across a ball from Banerjee, who then caught and bowled Chris Schofield off a leading edge to an attempted slog sweep as Surrey's tail folded meekly.

Gloucestershire outplayed their opponents in all departments and look set to be a one-day force again following the return of John Bracewell – the man who led them to five trophies in two seasons in 1999 and 2000 – as director of cricket.
