Jenkins was out in just the 22nd over for 77 off 65 balls, and helping lift Darfield to 249/8 in their allotted 45 overs.
Scott Burnett was the standout Cheviot bowler, claiming a five-wicket bag.
Shipley opened the Darfield bowling and removed Ted Whelan and the dangerous Harry Fitzpatrick, before Liam Foulkes' off-spin through the middle overs completed the dominant win.
Only Cheviot opener Ryan Ellis, with a well-made 61, showed much resilience at the Magpies collapsed to be all out for 129 in the 33rd over, falling to a heavy 120-run defeat.
Oxford-Rangiora, with a few of their consistent performers away, picked up a quality 80-run victory over Ohoka at Mandeville.
New opening pair of Jonty Fleming (44 off 68) and Eden Sinclair (40 off 90) set up the win with a fine 83-run opening stand, as Oxford-Rangiora made 169/8 in their 45 overs.
Ohoka, also depleted, never threatened the total especially after Jake Waghorn knocked off three key scalps at the top of the order.
Then it was Nathan Cook who stole the show. Cook's left-arm spinners tore through the remaining Ohoka batsmen who had no answer, leaving him with the quality figures of 6/22 off 6.3 overs.
Sefton overcame Leeston-Southbridge to claim a solid away victory, after defending 237/6.
Five Sefton plays scored more than 30, with Matt Laffey the pick, making a run-a-ball half-century
After Canterbury seamer Fraser Sheat blasted out three top-order wickets, Toby Doyle (49 off 57) and Chris Beatson (49 off 65) set about resurrecting the chase.
But when they fell in the 21st and 26th overs respectively, nobody else was able to step up and the visitors claimed a 72-run win.
In the final game of the round, Weedons walloped Lincoln by 83 runs, with Brad Nightingale the standout performer, top-scoring in the match with 64.
Southbrook had the bye.
