Asked to bat first, Warwickshire lost three wickets for 58 in the opening powerplay. Brett Hutton dismissed Vaansh Jani caught behind and captain Rob Yates, who top-edged a slow bouncer to slip. James had Zen Malik caught at gully.

On a tricky surface, Warwickshire stumbled to 121-6 after Kai Smith chopped on to seamer James, Alex Davies bottom-edged left-arm spinner Pocklington, and Jake Lintott top-edged a reverse sweep.

But Garton and Bamber transformed the innings, their stand a seventh-wicket List A record for Warwickshire against Notts.

Garton burst into life by smashing three fours in an over off rookie seamer Byron Hatton-Lowe. He lifted Farhan Ahmed’s off-spin over the long-on boundary and pulled James for two sixes, reaching three figures with his 10th four, from 87 balls. While he has five half-centuries in first-class cricket, his previous best List A score was 38.

Bamber, with a previous List A best of 21, hit seven fours before holing out to wide long-off. Taz Ali fell leg before to Pocklington and Oli Hannon-Dalby departed to the penultimate ball of the scheduled overs after Garton, having cramped up after clobbering Hatton-Lowe for his third six, was caught at long-off.

Slater twice needed on-field treatment for a muscle injury but he and McCann gave the Outlaws a solid platform, before Slater was undone by bounce and turn as Yates had him caught at point.

Two wickets in his first seven balls by leg-spinner Lintott raised Warwickshire hopes of atoning for defeat in their first outing against Northamptonshire two days ago, bowling both McCann and Outlaws captain Haseeb Hameed.

After Ben Martindale had sliced Yates to short third and Lyndon James miscued Lintott to mid-off, the Outlaws were 190-5, with 93 still needed.

But, with time still on their side, Verreynne and Pocklington stayed calm and added 82 in 86 balls before the latter departed for 31 from 45 balls. Ahmed also picked out a fielder but Hatton-Lowe struck the winning boundary with nine balls to spare.
