One-Day Cup: Leicestershire, Hampshire, Kent, Essex, Durham and Sussex all win

Rishi Patel has scored more than 1,400 runs in the County Championship this season including four centuries

Rishi Patel struck a career-best 161 as Leicestershire surged to the top of Group A in the One-Day Cup with a record-breaking win over Lancashire.

The Foxes piled up their highest ever total in List A cricket as they made 411-6 at Old Trafford with Colin Ackermann also cracking a century.

Keaton Jennings replied with a ton for Lancashire but they were bowled out for 317.

The Foxes leapfrog Hampshire who had earlier replaced Nottinghamshire at the top after beating them by 91 runs.

Elsewhere, Essex held their nerve superbly to win a thriller against Middlesex by three runs in Chelmsford to claim their first win, while Kent's 330-6 proved too much for winless Surrey who lost by 87 runs at the Kia Oval.

In Group B, four batters hit half-centuries as Durham beat Derbyshire by 54 runs while Sussex got their first victory at Somerset, inspired by another sparkling innings from Cheteshwar Pujara.

Patel lays foundation for massive Foxes total

On a belting track at Old Trafford, Leicestershire signalled their intent on making it a special night under the lights as Patel and Sol Budinger put on 159 for the first wicket in 21 overs after winning the toss.

That smashed the county's previous opening stand against Lancashire in limited-overs games of 124 set by Nigel Briers and Laurie Potter at Grace Road 37 years ago before Budinger was out for a 61-ball 81.

The quick loss of captain Lewis Hill and Peter Handscomb didn't slow momentum as Ackermann joined Patel in adding 110 for the fourth wicket.

When Patel was finally out after hitting 17 fours and five sixes in his 129-ball effort, Ackermann slipped through the gears to reach his third List A hundred with his second fifty coming off just 21 balls.

In the face of such a daunting target, Jennings did his best to be the linchpin as Lancashire chased their highest ever List A score to win.

At 152-2 after 19 overs, they were in a decent position but Vilas, going brilliantly on 57 from 32 balls, was farcically run out as Jennings sent him back following a reverse sweep off Ackermann (2-46).

Jennings powered on despite the mix-up but regularly lost partners as Lancashire's challenge faded.

Despite a county List A record stand against Leicestershire of 80 for the eighth wicket with Tom Bailey, who clubbed 60 off 42 balls, Lancashire finished well adrift as they suffered their first defeat by 95 runs.

Hampshire indebted to captain's knock

Nick Gubbins scored his eighth List A century in his innings against Nottinghamshire

Having thrashed Essex and then seen off East Midlands rivals Leicestershire - either side of their washout against Yorkshire - in their two previous games, Nottinghamshire chose to test Hampshire's in-form batters first after winning the toss at Welbeck Cricket Club in Mansfield.

At 62-4 after 15 overs it looked like Hants were about to crumble, only for captain Nick Gubbins to stand firm.

Impressively strong through mid-on and mid-wicket, Gubbins glued the innings together as he steered their recovery beyond 250 before they were bowled out with one ball of their 50 overs remaining, with in-form South Africa seamer Dane Paterson taking 4-41.

Gubbins' effort of 119, including 13 fours and two sixes, spanned three hours and 47 overs as he became the first visiting batter to score a century at Welbeck against Notts since games were first hosted there in 2015.

The home side's reply started badly with Ben Slater out to the fifth ball of their innings and, when skipper Haseeb Hammed missed a sweep to leg-spinner Mason Crane's second ball, Notts were 51-4.

A punchy stand of 44 for the sixth wicket between Matthew Montgomery and Liam Patterson-White offered some resistance before teenage seamer Eddie Jack (2-28) plucked out Montgomery's off stump for 44 to leave them eight down, as the 17-year-old claimed his maiden wicket in only his second first-team game.

Jack then took an excellent diving catch at long-off to remove last man Ben Hutton off Crane (3-38) as Notts were bowled out for 163 to slide to their first defeat.

Essex hold nerve to squeeze out Middlesex

Tom Westley notched the 29th half-century of his List A career against Middlesex

In the game between two sides without a win so far, Essex and Middlesex served up an epic night of drama at Chelmsford.

At 111-3 with nearly 32 overs left and skipper Tom Westley and Luc Benkenstein well set, Essex would have hoped for a total in excess of 300.

But two wickets fell quickly checking their progress before Westley found a lively ally in Charlie Allison (70) who then put on 64 with wicket-keeper Will Buttleman (32) once Westley had gone for 80.

Essex fell just short of 300 on 298-9 as Josh de Caires (3-52) took half of the six wickets to fall to spin.

Middlesex were then put well on the way to victory as captain Mark Stoneman (93) and Joe Cracknell put on 124 for the first wicket.

At 246-4 after with 14 overs to go, a win looked a formality but the loss of Ryan Higgins (25) triggered a collapse as Middlesex lost five wickets for 46 runs leaving them needing seven runs off 12 balls with only one wicket left.

Debutant number 11 Ishaan Kaushal was then dropped off his first ball by Buttleman off Westley, leaving Ethan Bamber to try to finish it in the next over from Beau Webster.

Bamber ran two off the third ball and looked like he'd at least tied the game when he edged the fifth down the deep third only for Allison's sensational diving stop saving a boundary. His return throw was perfect for Buttleman who demolished the stumps with Bamber short of his ground coming back for a second.

Surrey lose again

At the Kia Oval, Surrey's poor competition continued as they first watched Kent rack up their highest score so far - and second highest in 50-over cricket against the Brown Caps - as captain Jack Leaning (87), Daniel Bell-Drummond (65) and Alex Blake (62) propelled them towards 300.

Wicket-keeper Harry Finch (34) and Grant Stewart (26) crashed 60 off 30 deliveries between them to pile the pressure on, to leave Surrey 331 to claim their first win.

A 98-run stand for the second wicket between Ryan Patel (68) and skipper Rory Burns (43) laid a platform but when both were dismissed within four overs of each other, the home side's effort ultimately never recovered.

Jordan Clarke's 55 kept them faintly in the chase but when he was out to the off-spin of Hamidullah Qadri (3-50) Surrey needed almost 10 runs an over in the final nine overs, with three wickets left.

On-loan leg-spinner Matt Parkinson (4-43) then helped mop-up the tail as Surrey were bowled out for 243 with nearly seven overs remaining.

Pujara takes Sussex to thrilling first win

Cheteshwar Pujara now averages 151 in the One-Day Cup this season

Cheteshwar Pujara was again the star for Sussex as they chased down 318 to beat Somerset at Taunton in Group B, in a match that saw three centuries.

The India batter made an unbeaten 117 - his second ton of the competition - marshalling the visitors' reply superbly as they reached 319-6 with 11 balls to spare to topple Somerset, who had hoped hundreds from Andy Umeed and Ireland's Curtis Campher had given them a winning total.

Pujara's innings came off just 113 balls and was paced to perfection as he received noble support from Tom Alsop (60), wicket-keeper Ollie Carter (44) and spinner Jack Carson (22 off 12 deliveries).

Somerset's total represented something of a recovery after they stumbled to 80-3, with in-form James Rew out for 22.

But Umeed (119) and Campher (101) put on 163 for the fourth wicket, falling five runs short of a new record against Sussex, to get them back on track before captain Sean Dickson (40) helped add 49 from the last four overs.

But Pujara's brilliance ensured it was not enough, as Sussex finally won for the first time.

Durham see off spirited Derbyshire

Graham Clarke and former England batter Alex Lees gave Durham a superb start against Derbyshire at Chester-le-Street.

The pair put on 142 for the first wicket - a county record against Derbyshire in List A cricket - as they cashed in on being asked to bat first.

Lees then ran himself put attempting for run a bye off wicketkeeper Brooke Guest for 62, before Clarke was pinned LBW by left-arm spinner Mark Watt 11 short of a century.

When Scott Borthwick was bowled first ball by spinner Alex Thomson (3-53), a large total looked unlikely with Durham 218-6 with 15 overs left.

But Liam Trevaskis blitzed 76 from 54 balls, in another record stand against Derbyshire of 80 for the seventh wicket with Michael Jones (56), as the home side got up to 333-8.

Those runs were to prove crucial as the visitors made an excellent fist of their chase as Harry Came (44) and David Lloyd (30) gave them a solid start, before Wayne Madsen's 65 and Guest's 63 kept them in the hunt.

But Migael Pretorius (4-56) took two late wickets in as many overs as Derbyshire's spirited effort ended on 306 - 27 runs short.
