JER Lane remain unbeaten after five rounds of fixtures in the Foster's Halifax League.
However, the defending champions are not top as Mytholmroyd lead the way in the Premier Division on 52 points, with Jer four behind in second.
Lane returned to Copley, scene of their Parish Cup final defeat last August, and exacted revenge with a seven-wicket win.
A tough afternoon looked in store for the Bradford club when Chris Dennison (81) and Nick Gomersall (53) put on 135 for Copley's first wicket.
But Nabil Khan dismissed them both on the way to 5-89 off 19 overs and Copley had to settle for 210-6.
Lane knocked off the runs in 33 overs, with Wayne Cotton making 50 before Raqeeb Younas crashed eight sixes in an unbeaten 96.
Steve Senior, stand-in goalkeeper for Ovenden West Riding in their Halifax & District FA Cup final victory recently, hit 126 for Mythomroyd at home to Thornton, who lost by 198 runs, with Ross Parr taking 5-61 for the losers.
Booth were 32-run winners at Queensbury, despite 56 by No 9 Matthew Bruce and 5-64 and 37 from Gurdev Singh.
In Division One, Oxenhope's last pair denied Northowram Hedge Top maximum points but Chris Conroy's side will be happy with an Adam Stocks-inspired success after Jazdev Jheeta took 5-89 for Oxenhope.
He made 92 out of 253-9 and Oxenhope, in the hunt halfway through their reply, could not find anyone to hang around with left-hander Graham Smith (81) and never threatened the home total, although a late flurry of runs left them only 27 short.
Bridgeholme continued their pleasing start to middle-section life with a four-wicket win at Low Moor, who were dismissed for 143.
Low Moor slipped to the bottom as Stones knocked off 254 to beat visitors Bradshaw.
Cullingworth are the new leaders of Division Two after they amassed 329-7 en route to victory over Greetland, Antony Partington making exactly 100, Adie Powis 80 and Graham Rankin 48 before Dave Robinson took 4-26.
Matthew Jordan's 7-31 was the catalyst for Great Horton Park Chapel's nine-wicket victory over Shelf, who were dismissed for 105, Richard Hassall then making an unbeaten 55.
Old Crossleyans slipped to defeat at Clayton, for whom Andrew Sutcliffe made 61, while Denholme Clough were pipped by two wickets at home to Outlane.
