Littletown got the better of Murton for their sixth win of a decent first season in the league, despite being bowled out for 161 as Keith Chapman (3-49) and Thomas Spinks (3-16) held sway, backed by two wickets apiece from Chris Winn and Michael Coulthard.
Philip Bennett (59), Shashikant Kadam (28) and Matt Nixon (21) top-scored for Littletown, who then dismissed Murton for 102 in 27.1 overs, despite 24 from Ben Wicling and fellow opener Liam Aiken’s 21. Adam took 4-20 in 12 overs, with Steve Sorrell grabbing 4-23 and Tommy Hodgkiss 2-5.

In reply, opener Adam Thompson hit 41, with three fours and two sixes, with Paul Reddel hitting 22 and Ross Bainbridge 20 but Jamie Winn’s haul of 7-18 had the visitors all out for 117 in 25.1 overs.
