Thornton did their fellow Foster’s Halifax League title-hopefuls a massive favour by reeling in leaders Jer Lane following a comprehensive five wicket success.
Copley made sure that they benefitted as they picked up maximum points in an even more emphatic seven wicket victory at Sowerby Bridge which means they stay in second place.
Lane got off to a scorcher against third-placed Thornton, Andrew Pinfield and Raqeeb Younas putting on 130 for the first wicket.
Pinfield went on to make 61 while Younas provided a few fireworks with 18 boundaries in his 132.
Things fell apart somewhat as only two other batsmen reached double figures in a closing total of 251 for seven.
Thornton were 43 for two in reply, but 49 from Nikki Hutchinson steadied things before Josh Hutchinson smashed a vital mid-order 88 with Ross Parr, who had earlier taken three Lane wickets, remaining unbeaten on 52 as the visitors reached 257 for five.
Copley brought Lane’s lead down to just eight points with their success which was based on a fine bowling stint from Connor Turner and a smashing innings from James Clarke.
Bridge were always up against it after slumping to 96 for five, Paul Gledhill top-scoring with 55 in a closing total of 161. Turner was the man to do the damage, bowling 22 overs for a reward of five for 67.
Clarke then wielded the bat to excellent effect, punching an unbeaten 74 with Craig Taylor keeping him company at the other end on 39 not out.
Mytholmroyd piled further misery on bottom club Clayton in a high-scoring encounter.
Tom Earle blasted 85 at the top of the ‘Royd card and there were decent contributions throughout on the way to a healthy total of 290.
It could have been better had it not been for Sam Wilson producing figures of six for 74.
Wilson then played a major role in the reply, hitting 10 boundaries in a battling 75 batting at seven. Last man Joel Metcalfe also chipped in with an excellent unbeaten 63, but Clayton fell 54 runs short, Zahid Mahmood hastening their departure with five for 68.
Batsmen from Triangle and Booth clearly enjoyed themselves with a number making big scores in a game which saw Triangle emerge 86 run winners.
N. Madden made 83 at the top of the order with Chris Silkstone chipping in with 68.
However, it was Tony Sykes who pushed the scoring along with 110, while Jack Gledhill contributed 66 as Triangle made 379 for eight, Nigel Horsfall taking four for 78.
Booth had their share of big-hitters on show with Patrick Thomas making 63, Andrew Truscott 84 and Rob Layock an unbeaten 92. However, the overs ran out on their efforts at 293 for two.
Bradshaw teenager Joe Lewis will have reason to remember his contribution in Bradshaw’s 144 run success over Warley.
The under 15 player claimed a hat-trick which included dismissing the Keywood brothers with the last ball of one over and the first ball of the next. He followed that by having Luke Duckitt caught at mid-wicket.
Warley were hustled out for just 93 in reply to Bradshaw’s 237 for eight for whom Simon Collins was the best with 52.
Division One leaders Southowram were well beaten by second placed Queensbury at Old Guy Road, with spinners Amjad Ali and Girdev Singh claiming the honours.
Batting first, Queensbury moved steadily to 90 for four before a partnership of 65 between Singh (55) and Tom Watson (24) added some impetus to the innings.
With Nick Richardson plundering 21 from one over from Scott Griffiths the home men sailed past the 200 mark to end on 216 for nine.
Southowram spinner Andy Measey was the stand out bowler, capturing four for 59 from 16 overs while Gavin Moody proved difficult to score off.
Spinners Ali (four for 42) and Singh (four for 81) then bowled throughout the Southowram innings. With only Tandy (30) showing any positive intent against them the innings never got off the ground and at 86 for seven it looked as though the visitors might be dismissed for less than 100.
Three boundaries from Ashley Johnson (19) and some stubborn resistance from Mohammed Mushtaq and Andy Measey earned one batting point and denied rampant Queensbury a maximum 12 point win.
Sowerby St Peters consolidated their third position with a four wicket win over Outlane.
Martin Schofield proved the key man, his five for 85 helping to skittle the home side for 194 for nine.
Opener Ben Watkins hit 47 in Sowerby’s reply, but it needed Schofield’s 50 to help tip the scales in his side’s favour as they went on to reach 196 for six.
Bridgeholme collected what could be a priceless four wicket win over Northowram Hedge Top as they battle to avoid the drop.
Tahir Mahmood (three for 32) amd Allah Ditta (four for 39) kept Northowram in check after opener Kier Litjens had scored 63.
The target of 147 was within Bridgeholme’s capabilities, but at 98 for four the game looked to be in the balance.
However, Mohammed Basharat (41) and Oliver Challis (26) shored up the middle order as Bridgeholme met their target to bag the 12 points.
Shelf moved up a couple of places in Division Two after seeing off leaders Low Moor by 55 runs.
Steve Priestley defied all efforts from the Moor bowlers to dislodge him as he struck 22 boundaries in his unbeaten 124
Chris Wolfenden (42 no) joined him to help lift the total to 250 for five.
Moor were always in the hunt early doors but stalled at 178 for five, Mark Mills (50) and Charles Holdsworth (61) having provided the bulk of those runs.
The visitors then lost their remaining five wickets for the addition of just 17 runs, Robert Ramsden (four for 53) and Nick Patefield (five for 45) doing the damage.
Luddenden Foot remain second after their two wicket success over Augustinians.
Grant Helliwell claimed five for 46 as Augustinians were shuffled out for 165.
Chris Roy gave Foot a fine start on the way to making 63 and after a few wickets had gone down, the late order boys rallied round to take their total to a winning 166 for eight.
Greetland edged closer to mid-table security after banking 12 points from a 72 run victory over Stainland.
S. Malik (60) and Tariq Mahmood (84) laid the platform for a closing total of 270 for seven.
Stainland huffed and puffed, Ryan Severn again top-scoring but only managing 69 this time, as Malik (three for 42) and Mahmood (two for 40) returned to inflict further damage, this time with the ball.
Sadaqat Zaman was in good all-round form as Brighouse maintained their impressive form in Division Two of the Bradford League in defeating Keighley by two wickets.
Zaman claimed five for 39 as Keighley were shot out for 165. He then went on to make an unbeaten 39 as Brighouse eased home with 10 balls to spare.
Jack Beetham (56) and Amjid Hussain (33) were the top scorers for Keighley while Joe Stead (five for 48) was their best bowler.
It wasn’t such a good day for Lightcliffe in Division One as they suffered a five-wicket defeat against Pudsey Congs.
Alex Stead (68) and Jonathan Wilson (50no) top scored in Lightcliffe’s 180 for six, but the home side were prevented from posting a more challenging total by another good spell from left-arm spinner Glenn Roberts who took four for 30.
Congs eased home with eight balls to spare with opener Callum Geldart (68), Nick Lindley (32) and skipper Gareth Phillips (30no) leading the way.
Elland’s Huddersfield League Premiership victory at Kirkburton was unusual in that they were awarded five penalty runs by the local umpires for ‘persistent damage to the wicket’.
The one wicket win saw Elland go clear in second place, overseas man Rahul Bakshi top-scoring with 76.
Chris Greenwood took five for 33 as Barkisland inflicted a seven wicket defeat on Shelley.
The visitors were all out for 135 which skipper Darren Robinson helped knock off with an unbeaten 40.
Illingworth’s recent run of successes in Division Three of the Aire-Wharfe League came to an end at New Rover.
The Jammy Green side were handicapped by Aussie Matthew Battle being unable to ball due to a back injury while the previous week’s centurion Veryan Brooksby lined with a dislocated shoulder.
Illingworth started slowly on a wicket enlivened by midweek thunderstorms, but at 81 for two looked to be heading for a defendable target.
The first four batsmen all got starts but no one was able to push on ith James Lawton top scoring with 29.
Illingworth suffered a customary middle order collapse, losing six wickets for the addition of just 23 runs and it was only a brief rally by the tail with the last two wickets adding 42 that put a little gloss on the performance.
A target of 146 always looked light but Rover were made to fight all the way with Alex Ledger returning his best figures of the season of four for 38, aided by two smart catches from Ben Robertshaw and Richard Farrell Smith.
The difference between the sides was New Rover’s number three batsman Dinsdale who anchored his side’s reply to finish with an undefeated 60 and lead his team home by four wickets.
A career best unbeaten 92 by Ben Sutcliffe took Todmorden to a nine wicket win over Rishton in their Lancashire League clash at Centre Vale.
The opener hit 14 boundaries and passed 500 runs for the season during his innings.
He put on 71 with Simon Newbitt, who made 35 before falling to a Matt Lambert full toss, and an unbroken 98 with professional Geeth Alwis who was unbeaten on 26 when victory was achieved with almost 15 overs in hand.
Alwis had earlier taken five for 40 in Rishton’s 165 for nine. Professional Daniel Salpietro top scored with 38, Garth Wyse made a career best 32, Mo Patel 22, Lambert an unbeaten 19 and Craig Smith 19.
