SKIPPER Rory Hamilton-Brown's match winning knock fired Surrey to their their first silverware in eight years at Lord's.

The opener hit a match-winning 78 to lead his side to a five-wicket CB40 final win over Somerset.

It was a fifth straight cup final defeat for perennial runners-up Somerset, who made just 214, owing even that mostly to Jos Buttler's expansive 86.

Despite three rain breaks, Surrey then reached their revised target of 186 in 30 overs with 15 balls to spare.

"This feels pretty good," admitted a delighted Hamilton-Brown after the game. "Winning a trophy is a very special moment and it hasn't quite sunk in yet. I should have a decent stab at a five-month long celebration.

"But we're still a young side and I hope our best days are still ahead of us and that we can prove a force to be reckoned with.

"I don't care who gets the runs. I'm just glad we've won a trophy. But, if I hadn't got a score, then someone else would have done.

"We took wickets at crucial times when they batted and, in the end, after all the rain interruptions, we chased it down well."

Surrey had been without a trophy since their Pro 40 and Twenty20 double-winning year of 2003.

Despite having won the toss and opted to bat, and with Trescothick passed fit to play, still nursing an ankle injury, none of Somerset's top six got decent starts against a spin-based attack, in which England's latest South African recruit, Jade Dernbach, played the starring role, taking 4-30.

Had it not been for Buttler's late assault, hitting two sixes and seven fours in his 86 off 72 balls, Somerset would have not had any sort of total to defend.

As it was, when Buttler was last out to become Dernbach's fourth victim from the second ball of the final over, Somerset had at least taken their total past 200.

Somerset needed early wickets to stand any chance. And, although Murali Kartik crucially dropped Hamilton-Brown before he had scored, they made two breakthroughs around two brief rain breaks, Steve Kirby snaring Steven Davies before getting Jason Roy caught behind.

At 46-2 off seven overs, rain then forced the two sides off again, at which point the weather had caused so much delay that Duckworth/Lewis came into the equation.

Surrey's revised target was 186 off 30 overs, meaning another 140 needed off 23 at pretty much six an over. But although Arul Suppiah had Tom Maynard caught behind, Chris Schofield (26) helped Hamilton-Brown put on 58 for the fourth wicket.

Just when this pair looked to be cruising home, Schofield slammed it straight to Trescothick before Hamilton-Brown was run out by a direct hit from Buttler at mid-on.

But Surrey were to have the final say. Matt Spriegel (24 not out) and Zander de Bruyn (17 not out) saw their side home in the 28th over - to complete a memorable week for the Brown Caps, just three days after winning promotion back to the top flight in the County Championship.
