Only three additional runs were added to Worcestershire’s overnight total when Nick Potts completed the innings by dismissing Gibbon, leaving Derbyshire requiring 333 runs to win.
Allison immediately established Worcestershire’s dominance, claiming a double wicket maiden by catching Harry Came at second slip and then bowling Matthew Montgomery for a duck just two balls later.
Allison continued his onslaught, taking the 32nd and 33rd wickets of the morning as he dismissed Wayne Madsen and Yousaf Bin Naeem, collapsing Derbyshire to 32 for four.
Wickets kept falling; Martin Andersson was removed by Gibbon after a 21‑ball cameo, and Allison crowned a stunning display by securing his second five‑wicket haul of the match and third of the season with the dismissal of Brooke Guest.
Reece and Basra offered a brief resistance before lunch, adding 36 runs for the seventh wicket to bring the visitors to 75 for six at the break.
Reece anchored the chase in the afternoon, scoring a sturdy 49 off 67 balls, only to be dismissed one run shy of a well‑earned half‑century when he steered the ball to the impressive Allison.
Basra was removed by a sharp delivery from Gibbon, who bowled him for 40, and the seamer then had Shoaib Bashir caught at slip with the very next ball, edging Derbyshire closer to defeat.
Gibbon sealed the victory by dismissing Potts for 29, bowling out Derbyshire for 157 in the final over of the summer.
