Captain Tom Fleming was Bridlington’s match-winner as his goal saw off Garforth.
Playing in a more advanced role, Fleming netted the winner in the 56th minute, before later dropping back into his more familiar midfield role to help to keep the visitors at bay.
Town had enjoyed plenty of possession in the early stages, but they were grateful to keeper James Hitchcock for a fine double save to keep them level.
They eventually broke the deadlock three minutes before half-time.
A throw-in on the left found its way to Chris Adams and his shot took a slight deflection as it crept into the net, via the far post.
Garforth replied quickly, equalising in the first minute of the second half.
Town’s defence was sliced open far too easily and sub Ashley Preece set Mark Simpson through on goal and he tucked the ball past Hitchcock.
Visitors keeper Paul Hagreen was relieved to see the ball drop past the post after he palmed Benn Lewis’ effort up in the air, and he then dived to his right to beat away Ash Allanson’s piledriver from the resulting corner.
But the corners kept coming and Town made one count when Fleming, with his back to goal on the six-yard line, reacted quickest when a flag kick was nodded down and flicked the ball home.
Not the most elegant overhead kick, buteffective.
Garforth bounced back, and won the midfield battle, meaning Brid could never relax.
In injury time, Garforth should have equalised, when sub Chris Simpkins found himself unmarked six yards out but he headed Sinmi Oyebanji’s deep cross wide.
