Belper Strutt No 2 and Alfreton Palmer Morewood were both vying for top spot in Group B going into the final qualifying round of matches in the Bob McCartin Six Red Cup.
Andrew Beardsley is showing fine form in early season and continued his run of impressive performances with a 46-7 win in the opener to strike first blood for Alfreton.
However, Justin Weller equalised and then Keith Hubbold edged Belper ahead with a 39-19 verdict in the next.
Dave Needham made it 3-1 before Weller and Hubbold sealed the match in the first of the scotch doubles.
The visitors had to wait until the final frame before Beardsley and Ralph Edgson got them back on the scoreboard, though both teams will qualify for the next stage.
Belper Strutt No 1 were already through from Group C and were joined by Matlock Cons and Edgefold No 2.
Cons got the win they needed but only by the minimum margin, meaning both teams will progress into the quarter finals.
Gareth Johnson and Chris Parker saw the hosts 2-0 up before Gary Blackburn pulled one back and eventually Richard Deakin and Charlie Hodgkinson took the decisive scotch doubles leg.
In Group A Bolehill No 2 ended Edgefold No 1’s unbeaten run in all competitions 4-3 in the only other match.
Richard Ferguson (28 break) saw the Matlock side in front, but four unanswered frames sensured a home victory .
