HAMPSHIRE recorded their first totesport National League win of the season - thanks to a record-breaking performance at Lord's.

Simon Katich (85 from 63 balls) and Kevin Pietersen (80 from 50 balls) performed further heroics following their return to form in the championship at Canterbury as the Hampshire Hawks recorded a mammoth 353-8 - the county's highest score in the competition's 36-year history.

It surpassed the 335-6 that the Hawks made against Somerset at Taunton in 2003 to become Hampshire's highest total since the Sunday League began in 1969 - and it was the basis of a 105-run win at the home of cricket.

Katich scored a century in that game at Taunton two years ago and he provided a pulsating innings, scoring four leg-side sixes and eight fours before his 72-run partnership with John Crawley ended when he was caught at the wicket.

Left-hander Katich helped Hampshire get off to an electric start with the help of fit-again Nic Pothas (27 from 33 balls).

But after being dismissed midway through the Hampshire innings Australian international Katich was upstaged by Pietersen for the second time in three days.

Pietersen responded to his exclusion from the England squad by smashing SIX sixes on the ground where the first Test of the summer will be played against Bangladesh next week.

Pietersen's highest National League score for Hampshire came on the back of his maiden championship ton for the county and included one maximum that sailed back over the head of off-spinner James Dalrymple and into the middle tier of the Lord's pavilion. The 24-year-old had hit Dalrymple over the mid-wicket boundary moments earlier but that was not as brutal as the punishment reserved for Middlesex captain Ben Hutton.

Three successive deliveries from medium pacer Hutton were dispatched for sixes. The first two came from a no-ball and a free-hit and both sailed over the mid-wicket boundary and into the grandstand.

The third was lifted over long on and into the Compton Stand.

Pietersen put on 55 in seven overs with John Crawley (39 from 43 balls), who was caught after top-edging a sweep, and 66 with Greg Lamb, who was recalled after his excellent form for the second XI last week.

Lamb also scored at a fair lick (24 from 31 balls), lofting Paul Hutchison for a six of his own, before he was run out by a direct hit from Ed Joyce as Hampshire closed in on their record total.

The previous record was passed off the last ball of the penultimate over of the innings and Dimitri Mascarenhas (50 from 26 balls) took 17 off the last over from Scott Styris, which began with a six over mid-wicket.

Middlesex began the day at the top of the National League, having won all three of their games, while Hampshire had lost all three of theirs before making the most of a perfect batting track and a quick outfield after Shane Warne had lost the toss.

But of the Middlesex batsmen, only Owais Shah (89 from 64 balls) matched the sustained clean hitting of this Hampshire side.

He put on 68 for the fourth wicket with left-hander Ed Joyce (30 from 47 balls) but Middlesex's hopes of an unlikely win vanished when both were trapped leg before.

Hampshire's 105-run win was complete when they bowled Middlesex out for 248 in 39 overs, and it was fitting that Pietersen took the final wicket, when Hutchison nicked the ball into the hands of Warne at slip, after being given his first over in one-day cricket for the county.
