VAUXHALL MOTORS suffered a second half collapse as Blyth Spartans inflicted a worst defeat of the season.
The Motormen held a 2-1 half-time lead on Saturday afternoon at Rivacre Park but five goals in less than half an hour from the North East visitors stunned the home crowd.
Obi Anorou (25) and Leighton McGivern (45) made sure Carl Macauley's men held the advantage at the break, despite John Alexander pulling one back for Blyth.
However the avalanche of goals came when Stephen Turnbull (49) notched the equaliser before Paul Brayson (58, 68 and 76) and then Alan White (78) turned the game dramatically in the visitors' favour.
The 6-2 defeat leaves Vauxhall 15th in the Blue Square Bet North table.
Meanwhile, Marine did their hopes of securing a play-off spot no harm with victory over Bradford Park Avenue at the weekend.
Aaron Rey bagged the only goal of the game in the 56th minute to keep the Mariners in touch with those vying to end the regular season in the Evo-Stik Premier Division top five.
On Friday night, Burscough were edged out 1-0 by high-flying Buxton thanks to a Kieran Lugsden goal in the 16th minute.
Chris Simm scored two late goals to turn the game in Chester's favour against Harrogate Railway Athletic on Saturday.
The Evo-Stik First Division North leaders had fallen behind to Wayne Harratt's 13th minute strike but equalised through George Horan on 27.
However Harrogate shocked the home side just after the break when Steve Palfrey re-established their lead on 49.
However a double from Simm put Neil Young's men in front for the first time and keeps their lead at the summit intact.
