A sparkling innings of 70 by Ben Slater saw Chesterfield cruise to a comfortable win against Barnsley on Saturday.
The Yorkshire Premier team batting first struggled against a fine opening burst from Michael Deane who picked up three early wickets but Danny Rafiq led a recovery reaching 50 before retiring.
But Barnsley were bowled out for 166 in 48 overs as a string of Chesterfield change bowlers each claimed a wicket. Chesterfield then took full advantage of the improving conditions and a Brian Gladwin six that sailed out of the Shaw Lane ground secured a five wicket win at 167-5 with Slater retired 70 as one of the five wickets down.
Chesterfield had the poorer of conditions at Castleford on Sunday and were rescued from a precarious 78-8 as senior players Paul Burdett (48 not out) and Tim Kirk (26 not out) took their side on to a 45 over total of 129-8.
Castleford needed most of their overs to overhaul the Chesterfield total to record a five wicket win.
Chesterfield have a final practice match against Eckington mid-week before opening their league season at Alvaston & Boulton on Saturday.
