Kent's wait for silverware goes on after they were comfortably beaten by Hampshire in the Royal London One-Day Cup final at Lord's on Saturday.

Opener Rilee Rossouw's magnificent 125 helped lead Hampshire to a formidable total of 330-7 which also included an unbeaten 75 from former Kent skipper Sam Northeast.

Daniel Bell-Drummond (86) and skipper Sam Billings (75) led Kent's reply but the damage was done in the middle overs as the Hampshire bowlers, led by Liam Dawson, turned the screw.

It was Kent's eighth successive defeat in Lord's finals and they remain without a win at cricket's headquarters since their Benson and Hedges triumph 40 years ago.

After Sam Billings had won the toss and put Hampshire in on a true track left-handed openers Tom Alsop and Rossouw made serene progress with barely a false shot as they put together a century opening stand.

Kent's new-ball pair of Harry Podmore and Matt Henry bowled tidily enough but without getting past the bat too often and Hampshire finished the 10-over powerplay on 58 without loss.

Calum Haggett experienced a torrid initiation to the attack with four boundaries coming from his opening over and the all-rounder was withdrawn after just two overs, which cost 26 runs.

Darren Stevens and Joe Denly gave the batsmen a little bit more to think about but as the runs continued to flow Alsop was first to his fifty, getting there in the 17th over.

Hampshire's 100 followed in the next over, with Rossouw then greeting Henry's return to the attack by hitting him over deep square for six to reach his half-century.

The breakthrough finally came with the introduction of spinner Imran Qayyum, whose second delivery, in the 23rd over, tempted Alsop down the wicket to give Billings a comfortable stumping.

The Hampshire opening stand had been worth 136 with Alsop's 72 coming from 75 balls with 11 boundaries.

Hampshire reached the halfway mark on 157-1, with Rossouw and Vince (23) going on to add 57 before the Hampshire skipper clipped a catch to Denly at long on to give Qayyum his second wicket, in the 31st over.

Vince's departure brought Northeast to the crease and the former Kent captain was subjected to more than a few uncharitable boos as he came out to face his ex team-mates for the first time in a Hampshire shirt.

The 200 came up in the 32nd over and Rossouw continued to plunder on, bringing up his 12th List A hundred in the 35th over, from 97 balls.

He and Northeast had added 77 in seven overs when he chanced one big hit too many and holed out off Denly to Alex Blake at deep midwicket for 125, with the total at 270. The former South African Test man faced 114 balls, hitting nine fours and three sixes.

The same Kent combination accounted for Liam Dawson, caught at cover for eight, with the total on 287, as Denly remarkably produced a wicket maiden in the 44th over.

The Kent vice-captain then struck twice in the 46th over, seeing Sean Dickson hold a superb running catch in the deep to dismiss Lewis McManus (6) before trapping Joe Weatherley – a centurion in the group match between the sides – leg before without scoring.

That wicket left Hampshire on 297-6 and gave Denly a spell of 4-7 from three overs as he went onto finish with 4-57 off 10.

Haggett, brought back for the final over, bowled Gareth Berg for nine, but all the while at the other end Northeast carried on where Rossouw had left off, reaching his fifty from 43 balls before finishing unbeaten on 75, from 60 balls, with six fours and two sixes.

Qayyum finished with 2-60 from nine overs while Stevens bowled his 10 for 59. Podmore ended with 0-54 from nine overs and Henry – in his last appearance before returning to New Zealand – took 0-64 in nine. Haggett claimed 1-34 from his three overs.

Hampshire's total was a record for a One-Day Cup final but Kent openers Heino Kuhn and Daniel Bell-Drummond set about the chase with gusto.

They had reached 55 with relatively few alarms when Kuhn – the competition's leading run maker – went for a chancy single and was run out by Berg's direct hit for 32. He faced 39 balls hitting a six and four fours.

Denly fell for 12, chipping a catch to Vince off the bowling of Berg to make it 83-2, but Kent brought up their 100 in the 20th over, quickly followed by Bell-Drummond's half-century, secured with a boundary off Mason Crane – one of three in the over.

The opener survived a tough diving chance to Rossouw off Vince in the 60s, and at halfway Kent were 127-2, at which stage the run rate had risen above eight an over.

Spinner Dawson proved particularly difficult to get away, bowling his first seven overs for 23, while in contrast Mason Crane was expensive.

However recalled after his first three overs had gone for 29 the young legspinner claimed the third wicket, when he induced Dickson to sky the ball to Rossouw for 30. He and Bell-Drummond added 75 but Dickson managed just one four and one six in his 41-ball knock.

It meant that by the time skipper Billings arrived at the crease the pressure was on, and, as the run rate started to approach 10 an over, Bell-Drummond played on to Chris Wood having hit 11 fours from 89 deliveries.

Alex Blake (9) hit Dawson for six but was superbly run out two balls later with the total on 190 as he failed to beat Crane's direct hit from deep square leg after calling for two.

By now the task was already looking an uphill one, and when Stevens (12) and Henry (0) perished in successive overs all hope subsided.

Stevens was clearly angry with himself as he clubbed Dawson to Weatherley in the deep to leave Kent on 217-6 , and just one run later Henry hooked Dale Steyn down Alsop's throat on the boundary.

Billings did his best to keep the chase alive, completing an excellent half-century in 39 balls, but Hampshire's third direct hit of the day – this time by Vince – accounted for Haggett (1) as he attempted a single to mid off with the total on 241.

The fourth run out of the Kent innings came when Podmore (1) failed to beat Wood's throw to the bowler's end, at 256, with the innings wrapped up in the 48th over on 269 when Billings was caught by Steyn off Berg for 75, made from 60 balls with eight fours and a six.
