Worcestershire Seconds are leading the Second Eleven Trophy table ahead of Monday's clash with Durham at New Road (11 am start).
Coach Kevin Sharp's side boast a 100 per cent record after the opening four games of the 50 over competition.
The Seconds have defeated Warwickshire, Nottinghamshire, Derbyshire and MCC Young Cricketers.
It is a splendid effort after the challenges of last summer in white ball cricket for the Seconds.
The top two in each group automatically qualify for the semi-finals on June 2.
Worcestershire are a point ahead of second placed Yorkshire while Somerset and Middlesex currently occupy the top two spots in the South Group.
Each county plays six games in the group stages.
After facing Durham, Worcestershire wrap up their programme against Lancashire at Neston CC on May 22.
