Warwickshire 279 for 9 (Barnard 100) beat Sussex 275 for 8 (Alsop 68, Ibrahim 56, Haines 55) by one wicket

The 27-year-old all-rounder, who had earlier taken his 11th wicket in this season's competition, took his aggregate to 590 runs with 100, two days after he'd made 161 - his maiden List A century - against Durham. He has also scored three fifties.

Sussex had fancied their chances of ending a dismal campaign with only their second win when they had Warwickshire 126 for 4 halfway through their pursuit of 276 and again when they removed Barnard and Ethan Brookes, who'd put on 78 for the fifth wicket, in successive overs with 64 still needed.

Jake Lintott hit a breezy 28 but Henry Crocombe picked up two wickets to keep Sussex in contention and when last man Oliver Hannon-Dalby walked out Warwickshire still needed 13 off 16 balls.

Sussex had one last opportunity but sub fielder Zach Lion-Cachet dropped Danny Briggs on the boundary and Briggs swung the next ball over mid-on for four to seal his team's seventh win out of eight.

Barnard was stumped giving off-spinner James Coles the charge, having hit nine fours and twice cleared the short boundary on the eastern side while Brookes (43) was leg before sweeping Bertie Foreman in the next over.

For Sussex it was a seventh defeat in their eight games, a bitter disappointment after they reached the last four a year ago, although this was a much better performance.

Put in by Rhodes, their 275 for 8 featured three half-centuries, but no one was able to push on and make the big score that would have given them a more competitive total on a slow pitch.

At least Sussex made a decent total without a major contribution from Cheteshwar Pujara, who was leg before to Henry Brookes for 23 from 40 balls and looked unusually out of sorts.

Warwickshire bowled tightly. The competition's leading wicket-taker Hannon-Dalby claimed his 24th victim when Ibrahim feathered an edge to wicketkeeper Kai Smith and there were two wickets for leg-spinner Lintott, who pinned Haines leg before to end a second-wicket stand of 83 with Alsop.

Alsop has been in poor form in the tournament with single-figure scores in five of his previous seven innings but looked more assured until holing out in the deep to give Lintott a second wicket.

Ibrahim and Foreman swelled the total in the closing overs, their partnership spanning just 35 balls with Ibrahim's 56 coming from 46 deliveries.
