Dulwich lost their fourth game on the bounce at the weekend when they fell to defeat against Cheam Cricket Club (CC).
The Southwark side made 219 when batting first but Cheam reached their target with the loss of just four wickets to register a six wicket victory.
Their latest loss comes on the back of a reverse against leaders Walton on Thames, which was preceded by other defeats against Epsom CC and Esher CC on the two previous weekends.
This poor run of form means Dulwich now sit at the bottom of Division Two of the Ryman Surrey Championships.
