Yorkshire moved to second place in Division Two of the NatWest Pro40 League after defeating Glamorgan Dragons by 49 runs at Scarborough.

Set 231 to win, Glamorgan's run chase was halted by bad light immediately after former Tyke Alex Wharf had been dismissed by Darren Gough.

That left the Dragons on 135-7 in the 30th over, Yorkshire winning under Duckworth-Lewis regulations.

Glamorgan were ahead of the required rate until Mike Powell was out.

He steered Rana Naved to Richard Pyrah at backward point and then Deon Kruis bowled Tom Maynard to return the tidy figures of 1-26 from eight overs.

Glamorgan slumped to 71-4 in 16 overs as Gough bowled Jamie Dalrymple and rain was starting to fall when Pyrah bowled David Hemp.

Although the rain stopped, bad light made it impossible to complete the match.

The bulk of Yorkshire's runs came from a 164-run partnership for the third wicket between Jacques Rudolph and Anthony McGrath.

After a slow start to his innings, South African Rudolph dashed on to 84 off 93 balls with 11 fours and a six while McGrath smashed 73 from 96 deliveries with four fours and three sixes.
