Dunstable dropped to fourth place in the Saracens Herts League Championship after a poor batting performance during their top-of-the-table clash against West Herts on Saturday.
Jack Kilduff took his first five-wicket haul for the club with 6-33 as the visitors were restricted to 221-9.

Dunstable struck a reasonable 194-9 on a difficult pitch with Ned Whitney top scoring with 52, whilst Richard Kilduff added 33 and Sam Marshall 24.
Marshall, Joe Thorne and Adam Lewis then all took three wickets as Dunstable bowled Watford out for just 91 in 26 overs.
Adam Stearn top scored with 26 for the IIIs as they struggled to 116-9 from their 53 overs against Old Elizabethans IIs as Ian Horton managed 25. Joe Moss, Tarnjit Biryah and Ayaz Ahmed claimed two wickets apiece but Old Elizabethans reached 117-7 with over 18 overs to spare.
The IVs had to concede again due to poor availability.
Dunstable’s Sunday first team claimed a dramatic win over Luton Town and Indians as Rob Simpkins’ single off the final ball of the match was enough for victory.

Ned Whitney (39) and Josh Thompson (37) set Dunstable on their way before Harry McBrearty’s crucial 29 not out late on saw Dunstable home.
Ben Adamson took 3-33 and scored 33 for the IIs but they were bowled out for just 156 by Harrold.
