Michael Lumb continued his excellent form as a 43-ball half-century carried Hampshire to a nine-wicket win under the Duckworth/Lewis method in their NatWest Pro40 League Division One match with Durham.

Lumb followed his 219 in the LV County Championship match at Trent Bridge last week with an unbeaten 57 out of a total of 87 for one after 11 overs, which put Hampshire well ahead of their target when bad light ended play at Chester-le-Street.

The target at the start of their innings was 197 in 31 overs, but the game's third interruption for rain came when they were 12 for one in the third over.

On the resumption the revised target was 163 in 24 overs and once Lumb and 18-year-old James Vince had taken 17 off the sixth over, bowled by Ben Harmison, they were always well ahead of the required rate.

After choosing to bat, Durham had reached 145 for three after 28 overs when the rain first arrived. The contest was initially reduced to 36 overs a side and they finished on 207 for five after Kyle Coetzer took three fours in an over off Chris Tremlett in plundering 29 not out off 18 balls.

More rain delayed the start of Hampshire's innings, then Jimmy Adams departed to the first ball of the third over, when a skied pull off Mitchell Claydon was very well caught by Ian Blackwell, running round from short fine leg.

But Vince struck the ball very cleanly in his 22 not out, while Lumb reached his 50 with his only six, cleanly struck over extra cover off Will Gidman. He also hit 10 fours.

Phil Mustard and Shivnarine Chanderpaul made half-centuries for Durham, both at roughly a run a ball.

It was Mustard's third 50 in four Pro40 League games this season, but before he could add to it he was run out.

Harmison turned left-arm spinner Liam Dawson's first ball to deep midwicket and went back for a second run which left Mustard with no chance of beating Vince's throw.

Mustard opened the scoring by lifting Dimitri Mascarenhas' third ball of the match over long-off for six. But he played responsibly after Blackwell drove at Dominic Cork and edged to wicketkeeper Tom Burrows in the second over.

Chanderpaul had to wait for Harmison to get out, hitting across the line at Imran Tahir, before going to the crease in the 20th over.

He completed his half-century with an exquisite square drive off Cork in the final over before holing out at long-off for 54.
