Championship leaders Doncaster Town romped to an eight wicket win at struggling Hallam B.
New signing Duncan Heath continued his impressive start to the season, shining with bat and ball.
The comfortable victory made it three wins from three for Doncaster since their relegation from the ECB Yorkshire South Premier League.
Town invited their hosts to bat first and Robert Basu (22) and stumper Matthew Godden (45) took the score to 52-1.
At this point spinner Heath joined the attack and the innings collapsed as Basu was removed and four batsmen followed without scoring.
Hallam were all out for 88 and Heath finished with superb figures of 6-18.
In reply Paul Van Den Heuvel (43) and Heath (40no) built an opening partnership of 84. Doncaster eased to victory with eight wickets to spare.
Conisbrough paid the price for conceding too many extras as they lost by just four runs against Whiston Parish Church at St Peter’s Drive.
Sri Lankan Nisala Gamage once again impressed for the Doncaster club, claiming 5-45.
But the extras (48) ended up as second top scorer for Whiston who posted 204.
Amit Kundra opened with 34, Gary Strephan hit 36 and Jack Whittaker looked as though his contribution could be the winning one.
But in a tense conclusion Whittaker was left 70 not out when the final Conisbrough wicket fell on 200.
