Bourne Town picked up three more points at the expense of their lowly visitors.
Zak Munton’s 32nd-minute goal had the Wakes ahead at the break.
They had to wait until the closing stages to seal victory with Tyler Sculthorpe scoring Bourne’s second after 76 minutes and Munton making the points safe ten minutes later.
Sean Barker scored a last-minute consolation for the Saints.
Bourne are up to seventh in the league table after ending a run of four games without a win which had seen them knocked out of two cup competitions.
They return to action at ON Chenecks on Saturday.
