Surrey held their nerve at The Oval to beat Hampshire by just one run in a thrilling final over, despite some heroics from 19-year old tailender Hamza Riazuddin.

Jade Dernbach began the last over with Hampshire on 112 for nine, needing 14 more, but Riazuddin carved two boundaries from the first and fifth balls and faced the final ball needing another four for victory.

Dernbach held a hurried conference with Usman Afzaal, his captain, and several other Surrey players, and then bowled full and straight.

Riazuddin managed to hit the ball out towards the cover boundary, but James Benning made sure of the stop and two runs were not enough.

It was Surrey's second win from three matches in the Twenty20 Cup South Division, and Hampshire's first defeat.

Another player at the heart of Surrey's tigerish display in the field was Chris Schofield, the leg-spinning all-rounder who was in England's inaugural World Twenty20 squad in South Africa in September 2007.

Schofield may have only scored 11 runs but he took the vital wicket of Chris Benham, who had earlier swept him for two sixes over mid-wicket in a top score of 39 from 37 balls, and also pulled off two magnificent direct hit run-outs of Jimmy Adams and Nic Pothas to further undermine Hampshire's chase.

It was no surprise, on football's Champions League final night, that only around 5,000 turned up on a gloomy evening that always carried the threat of rain.

But they were rewarded with an exciting - if low-scoring - contest in which Hampshire initially slid to 34 for three in reply to Surrey's 125 for eight before rallying through Benham and Michael Carberry.

At 91 for four after 15 overs, indeed, it was Hampshire who were clear favourites.

But Schofield's strike to get rid of Benham began a collapse in which he ran out Pothas from short mid-wicket, with the Hampshire wicketkeeper punished for backing up too far.

Dimitri Mascarenhas was bowled by Dernbach, returning from a two-week injury lay-off, and Imran Tahir was also bowled, swinging wildly at Grant Elliott's medium pace, in the penultimate over.

Michael Lumb had earlier been stumped off Matt Spriegel from the second ball of the Hampshire innings as Surrey, exactly like their opponents earlier, were rewarded for the imaginative ploy of opening the bowling with a spinner.

In Surrey's innings, it was Usman Afzaal who gave Liam Dawson, the slow left-armer, a return catch.

Schofield ran out Adams from mid-on and Sean Ervine's brief but explosive innings of 25 was ended by a well-judged catch at deep mid-wicket by Benning.

Benham and Carberry, once of Surrey, added 56 in nine overs for the fourth wicket but, in the end, it was not enough.

Scott Newman and Mark Ramprakash both hit early sixes in the Surrey innings, but apart from some late hitting by Benning and Gary Wilson the only real Surrey innings of note came from Stewart Walters, who scored 30 from 22 balls before being bowled by Mascarenhas' second ball in the 10th over.
