Match report
Leicestershire rewrote their record books in hammering Warwickshire by 103 runs in the Royal London One-Day Cup.
Batting first after winning the toss, the Foxes smashed 363 for seven off their 50 overs, their highest List A score against another first-class county.
The foundation of the score was a superb List A personal best of 159 from opener Mark Pettini, hit off just 135 balls and including 19 fours.
With the game being played on a pitch which had yielded 680 runs in less than 100 overs in the match against Worcestershire two days earlier, Leicestershire openers Pettini and Cameron Delport knew they had to get their side off to a fast start.
They did exactly that, hitting 76 off the first eight overs before Delport, on 34, swept Josh Poysden powerfully to backward square leg where Sam Hain took a fine catch two-handed to his left.
It was the first of four catches for Hain, but the next was a long time coming as Pettini and Aadil Ali added 104 in 20 overs for the second wicket.
Ali, making his second first-team appearance of the season, looked as impressive as he had in scoring 88 against Worcestershire and this time made 52 before his attempt to loft Jeetan Patel over long-on failed to clear Hain.
With Pettini busy and productive, mixing a series of wristy flicks through the leg-side with perfectly placed cover drives to the off-side boundary, the rest of the Leicestershire batsmen had licence to hit.
Mark Cosgrove middled a couple before holing out, but Tom Wells hit four sixes straight down the ground in going to his half-century off just 36 balls.
Though Pettini became the third to be dismissed by the safe hands of Hain, trying to lift Keith Barker over long-off, the late clatter of wickets did little to slow the scoring rate.
Warwickshire's reply began badly when Will Porterfield was adjudged leg before to Dieter Klein's full, fast first delivery. Jonathan Trott also fell to Klein, edging an attempted drive behind the wicket, but Hain and Ian Bell ensured the visitors' run rate initially did not fall too far behind that required.
Their partnership had reached 68 when Bell mistimed a drive at Wells and was caught low down by Ali at extra cover.
With Hain ticking over at a run a ball, Tim Ambrose hit consecutive boundaries off both Wells and Jamie Sykes before Hain's reverse sweep off Delport brought up the 200 at the end of the 33rd over.
Hain went on to bring up his hundred off 102 balls and Warwickshire still had hope but an outstanding catch by Ali, running back from mid-on and holding a skier as it fell over his shoulder, began a collapse that saw Warwickshire lose their last seven wickets for just 31 runs as Wells and Gavin Griffiths finished with three apiece.
