Promotion-chasing Alfreton CC suffered a setback as Marehay stormed to an impressive victory on Saturday.
Batting first, Alfreton got off to a shaky start as they lost Graham Bush for 4 with captain Mace following as he was removed for 1.
Christian Pratt (40) and Andy Gwatkin shared a 50-run partnership before the latter fell for Dean Mills for 28.
Jake Simpson then fell to Ben Perry-Taylor to give him his first wicket before he then removed mainstay Pratt to leave Alfreton teetering on 92-5.
Bilawal Bhatti was the only batsman who hung around as he scored 61 off 54 deliveries before he fell late on to Perry-Taylor, Alfreton finishing on 177 all out, and Perry-Taylor finishing with figures of 7-58.
Marehay’s chase started off in emphatic fashion as openers Stephen Lee (80) and Jonathan Bradder (62) shared a 124 run opening partnership.
The damage was already done before Mace removed both openers and Marehay cruised to victory by 8 wickets.
On Sunday, Alfreton were hoping to bounce back in the Marston’s Smooth Trophy final.
Alfreton bowled first and soon had Matlock on the ropes with early wickets from Alex Mace (4-40).
A good middle order partnership from Devon Conway (32) and John Aspinall (37) guided Matlock to and past 100, before Stuart McRobert removed both batsmen as Alfreton wrestled back control.
However, late order resistance made sure Matlock batted out the 50 overs and set a competitive total of 167-9.
In reply, Pratt and Mace fell early before Bush and Gwatkin rebuilt the innings. Gwatkin fell next but Bhatti joined Bush and the innings kicked on.
However, when Bush fell for 33, stability in the Alfreton innings went with him and regular wickets saw Alfreton’s chase stymied.
These regular wickets, especially when Bhatti fell for 30 ensured Alfreton could not reach their required target as they finished 139 all out, Conway finishing with figures of 3-27.
Alfreton have a double-header next weekend on the last weekend of the season which with two wins could see Alfreton playing in the Derbyshire Premier League.
