It may have been pulsating holiday entertainment but there were anxious moments for the home fans before Yate emerged with the three points needed to keep up the pressure on table-toppers Blackfield and Langley, writes John Davis.
Despite their lowly position, Mangotsfield pushed the home side all the way-coming back from behind on three occasions and almost salvaging a point with two late chances.
A scrappy opening spell was finally given a lift after 18 minutes when Mike Bryant and Ross Langworthy combined well to play in Dave Sims-Burgess who moved to the right of the goal before firing across Kieran Hodges into the far corner.
The impetus was then ramped up considerably with a burst of three goals in a three minute spell. Luke Spokes put United level after Yate had given the ball away, Jack Twyman headed home a cross from Langworthy to make it 2-1 to Yate and then Kyle Tooze found the roof of the net with a rising drive to make it two goals each.
There were further chances at both ends before the home side edged 3-2 ahead at the break, Josh Ford getting up to head in an Adam Price corner from close range.
After Mangotsfield had penalty appeals waved away when Spokes went down in the box midway through the second half, Matty Tanner levelled the scores at 3-3 when he forced the ball home through a crowded goalmouth.
Play then ranged from end to end until Yate got back into the driving seat when Sims-Burgess robbed a hesitant Sekani Simpson and went on to play the ball round the advancing Kieran Hodges into the net.
The action continued unabated until the end. Price shot wide and Bryant was denied by Hodges at one end while Mangotsfield almost snatched a point when Spokes hit the crossbar with a header from a free kick and a long range drive from Tanner sailed just wide of the post.
