Somerset 250 for 9 (Allenby 69, Jayawardene 55) beat Hampshire 245 (Smith 59, Adams 50, Groenewald 3-56) by five runs
Scorecard

Mahela Jayawardene and Jim Allenby both scored half-centuries to set Somerset up for a five run victory, knocking Hampshire out of the Royal London Cup in the process. Somerset already had their South Group top spot guaranteed with Essex's washed out game at Gloucestershire and will face Worcestershire in the quarter finals.

Hampshire went into the final over needing 14 to win with two wickets in hand but Gareth Andrew fell to Tim Groenewald's first ball, via a steepling catch. Mason Crane and Brad Wheal scampered nine off the next four deliveries but Groenewald sealed victory with a catch off his own bowling.

Two wickets a piece from Lewis Gregory, Roelof van der Merwe and Max Waller helped complete the victory in tense circumstances.

Jayawardene and Allenby, who had won the toss and batted in gloomy conditions, appeared in little trouble as they put on 108 for the first wicket. Former Sri Lanka international Jayawardene was the first to reach fifty, from 54 balls, before he was followed to the milestone by Allenby, who had earlier passed his 2500 List A runs, in 62 deliveries.

But the partnership, which had come in little over 20 overs, ended when Jayawardene slogged Crane to Jimmy Adams at long on, who slipped but held the catch. Allenby departed nine overs later spooning a catch to Gareth Berg at short fine leg, to start a regular fall of wickets for the visitors.

Tom Abell was bowled round his legs by Crane and Peter Trego caught on the fine leg boundary ropes by the spinner after an industrious 31, including two huge sixes over the leg side.

Hildreth was unlucky with his dismissal as Andrew produced an outrageous one-handed catch at backward point before Gregory was bowled by Liam Dawson. Ryan Davies was caught by long-on Will Smith, Groenewald was on the wrong end of a fleet-handed stumping and van der Merwe was the last man back in the shed but the visitors reached 250 for 9.

Adams and Tom Alsop attempted to follow the example set of Allenby and Jayawardene by steadily accumulating runs in the chase but could not have the same effect as Alsop was lbw to Gregory after a stand of 49. Adams, reached 3500 career format runs, on his way to his 27th limited-overs half-century off 58 balls but after facing just one more ball was trapped leg before by van der Merwe.

Adam Wheater was also adjudged lbw to the slow left-armer before stand-in skipper Liam Dawson and Smith added 30 for the fourth wicket to keep the score ticking. But Dawson became the fourth player to fall leg before as Hampshire felt the squeeze, the run rate dropping to three an over.

A frustrated Ryan McLaren was bowled trying to give himself more space, while Smith reached fifty in 77 balls.

Hampshire needed 83 from the final 10 overs, and lost the important Smith when he was caught behind and Gareth Berg was run out attempting an over throw. That left Hampshire 192 for 7 but Lewis McManus and Andrew kept Hampshire in the hunt with a partnership of 32 in 4.2 overs.

Andrew struck a sweet six over midwicket and a swept four but Groenewald took his 100th List A scalp when McManus was bowled and although Wheal hit a four and a six in Gregory's penultimate over it was not enough.
