Whitburn succumbed to a six-wicket defeat in their trip to Hetton Lyons.
Opener Daniel Shurben top-scored with 44 as the Villagers were all out for 149, with Ross Carty adding 32 and Luke Smith 18.
Four Lyons bowlers - Eddie Watson, Ben Whitehead, Mahesh Rawat and Cameron Grimwood - took two wickets apiece to set up their victory push.
Chris Martin’s unbeaten 67, with 11 boundaries, proved decisive, backed by 34 from Rob Talbot and 30 from pro Rawat, with six and five boundaries respectively. Ian Elliot (2), Craig Smith and Mark Elliott took the wickets to fall as Lyons reached their target for the loss of four wickets.
Chester-le-Street are in scintillating form, crushing bottom club Gateshead Fell by 55 runs at Eastwood Gardens.
The visitors won the toss and elected to bat and, after the early loss of James Thompson, opener George Harrison (101 off 151 balls, including 13 fours and a six) and Richard Waite (49), put on 91 together for the second wicket.
A further partnership of 82 between Harrison and skipper John Coxon and then 64 with Liam Simpson (44), allowed Coxon to declare after 54 overs and give his bowlers time to bowl Fell out, which they did.
However, the returning Graham Onions had other ideas and he hit a fine 92 for the home side, including 15 fours, putting on 82 runs with Sam Roseby (35) for the fifth wicket.
Gurman Randhawa (3-51) and Quentin Hughes (3-20) eventually proved too much to handle and Fell are now in serious relegation trouble, 63 points adrift at the bottom.
The battle at the bottom ended in a draw.

He put on 116 for the fourth wicket with Sameet Brar (48) then added 87 with Mark Dale (45) and declared the innings closed for a massive 282-6.
In reply, Eppleton dug in and Kyle Davis (33), Liam Mallaburn (34) and Jack McBeth (51) batted well to ensure the draw. Of the nine bowlers used by the home side, only Brar, with 3-70, made any inroads.
Durham Academy have only lost one of their last nine league games and continued their excellent form with a six-wicket win against Tynemouth, denting the team from the Preston Avenue club’s title ambitions along the way.

Christopher McBride, with 34 off 52 balls, and Ross Greenwell’s half century (51 off 133 balls), slowly led their team to victory and they now move into sixth place.
