The two remaining Norfolk sides in the National Club Championship are set for a showdown this weekend.

Vauxhall Mallards will face Great Witchingham on Sunday in the group semi-final of the Kingfisher Beer Cup after both teams recorded comfortable wins in their second round ties last weekend.

Mallards registered an eight-wicket win at reigning East Anglian Premier League champions Cambridge Granta.

Skipper Paul Bradshaw removed both Granta openers with only 20 runs on the board, before Stuart Lipshaw's five-wicket burst saw the hosts fold to 130 all out in the 40th over. The off-spinner claimed five for 23.

Carl Amos and David Turner put on 70 for the first Mallards wicket and Amos went on to steer the visitors to victory in the 40th over with an unbeaten 72 from 104 balls.

Witchingham thrashed Boston by 205 runs as Sam Arthurton, pictured, hammered a century.

Arthurton made 133, while James Hale (48no) and Carl Rogers (41) also contributed in a total of 279 for four from their 45 overs.

Boston were then skittled out for just 74, with Jonathan Spelman claiming four for 32 and two wickets apiece for James Spelman and Tom Collishaw.

Sunday's match at Great Witchingham starts at 1pm.
