Relegation fears worsen for Grimsby
Ashley Westwood and Clayton Donaldson scored second-half goals as 10-man Crewe saw off battling Grimsby 4-2 at the Alexandra Stadium.
The home side cold have been out of sight after half an hour but Donaldson and Shaun Miller were thwarted by a string of fine saves from Nick Colgan.
The Alex took the lead in the 29th minute though, Joel Grant nodding down Westwood's centre before Byron Moore swept home from 12 yards.
The lead lasted just three minutes as Grimsby striker Jean-Louis Akpa Akpro shot between defenders John Brayford and Danny O'Donnell and found the far corner of the net.
But, just two minutes later, Moore returned the earlier favour to set-up Grant for a precise side-footed finish.
The battling Mariners were level again four minutes before the break though, as Brayford's loose headed clearance fell to Nick Hegarty who picked out Dean Sinclair to net from six yards.
Crewe moved 3-2 ahead 10 minutes after the break, Donaldson's cut-back found Westwood 25 yards out and the midfielder drilled a stunning first-time finish into the roof of the net.
Steve Phillips pulled off a stunning save from Lee Peacock's close-range header to keep the Alex in front, and Carl Martin was harshly sent off for a late challenge on Michael Leary before Donaldson put the result beyond doubt with a solo effort at the death.
