A superlative all-round performance by Liam Dawson helped Hampshire secure a fifth win of the Royal London One-Day Cup campaign and sent his side top of South Group, as they defeated Surrey by 53 runs at the Kia Oval.

All-rounder Dawson continued his impresseve early season form by hitting a 93-ball 108 in Hampshire’s 307 all out and then taking 2 for 39 with his accurate left-arm spin as Surrey were dismissed in reply for 254 in 46.2 overs.

Dawson, who hit four sixes and seven fours, now has 232 runs at an average of 46.40 in the competition so far, plus 13 wickets at just 18.00 from his 59 overs bowled, at an econony rate of just under four runs per over.

The 29-year-old came in at six with Hampshire stuttering at 124 for 4 after being put in to bat

Tom Alsop departed early, well caught at slip by Rory Burns off Stuart Meaker, and after some glorious shots – one of his five fours was a magnificent back foot force through mid off – James Vince was bowled for 28 by a superb ball from Meaker.

Sam Northeast played nicely for 24 before being bowled by a Ryan Patel nip-backer that looked to have caught a thin inside edge before disturbing the stumps and Rilee Rossouw was dismissed by medium pacer Patel, shortly after.

Meaker, the pick of Surrey’s seamers with 3 for 58, later removed Gareth Berg for 15, caught in the deep, but was withdrawn from the attack when sending down a second full toss over waist high towards the end of his ninth over.

By then Dawson had rallied Hampshire, initially in a partnership of 77 in 14 overs for the fifth wicket with the composed Aiden Markram, whose brilliant 88 from 90 balls featured nine fours.

Markram eventually fell to a good running catch at deep mid wicket off Will Jacks’ off spin and paceman Conor McKerr, who had suffered earlier at the hands of Vince, who hit him for three fours in one over, returned strongly to snap up three lower order wickets – first that of Aneurin Donald for 12 and then James Fuller and Kyle Abbott in successive balls.

Dawson, who reached three figures with a four swatted past mid on off McKerr, flipped Jordan Clark’s seam-up for six behind square leg at the start of the final over before being caught on the boundary from the next ball.

Surrey’s reply only really threatened when openers Mark Stoneman and Jacks put on 66 with some ease – Jacks playing one gorgeous straight drive for four and then flicking fast bowler Brad Wheal almost contemptuously for six to wide long leg.

Dawson, who had been brought on to bowl the 11^th over, made the breakthrough in his second over when he turned one enough to have Jacks caught at the wicket for 29.

Dean Elgar got himself into a tangle against a short ball from James Fuller on 5 and gloved a catch to keeper Alsop, and Stoneman’s excellent 70 off 68 balls, with a six and 10 fours, ended tamely when he miscued Markram’s off spin to point.

A promising 19 from Ben Foakes also finished in disappointing fashion when, aiming towards mid on against Berg’s medium pace, he lobbed a catch to mid off.

Dawson struck again when he had Burns caught for 38 in his penultimate over and, with 132 more runs still needed from the last 15 overs, the Surrey innings slid to 202 for eight, as Abbott and Fuller whittled their way through the lower order, before some defiant late blows from Freddie van den Bergh and especially Meaker, who flipped an extraordinary six over the keeper’s head off Abbott before holing out on the cover boundary next ball for 27.

Hampshire have now won five of their six group matches and are close to securing qualification to the knock-out stages, but for Surrey it was a fifth defeat in six games.
