Lewis Millington and Jair Minors had fired the Pilgrims into a 2-0 lead after half an hour at The Jakemans Stadium and although the visitors responded before half-time, Millington added his second and United’s third on 71 minutes.
Humbertherm cut the deficit three minutes later and equalised three minutes into stoppage time to seal United’s second 3-3 draw inside 48 hours.
