LEEK plunged Burslem deeper into the relegation mire with a comfortable 108-run victory in the Potteries.
Paul Hammersley (3-18) and South African Jean Rossouw (3-35) played a big part in reducing Burslem to 94 all out.
At one stage, the home side were 16-4 against the defending Premier Division champions.
Chris Roberts made 24 in the middle order, but the damage had already been done.
Leek had earlier run up 202-9, thanks to solid contributions from skipper Greg Willott (49) and his Staffordshire county team-mate Alex Thomson (40).
Rutvik Botadra (4-47) and Michael Brown (3-56) toiled in vain to stem the runs tide.
It was a 'must win' match for Leek in their fight to get away from the relegation zone.
Burslem are now 45 points adrift from safety in bottom spot.
