Dagenham & Redbridge left it late to beat Rochdale 2-1 on Saturday.
The Daggers had dominated the first-half and squandered numerous chances through Brian Woodall and Sam Williams.
Surprisingly it was Rochdale who looked like the better side after half-time.
The visitors had numerous chances in the first 20 minutes of the second-half but it wasn't until the 72nd minute that they took the lead through Andrew Tutte - the ball was cut back from the by-line for Tutte to put in the top right-hand corner past trailing keeper Chris Lewington.
However the lead only lasted three minutes, as sloppy defending allowed Daggers captain Abu Agogo to get an easy tap-in.
Daggers then finally got what they deserved after consistently applying pressure, three minutes into stoppage time. Sam Williams passed to Medy Elito in space to fire past Josh Lillis in goal, and gain a dramatic win for the League Two side.
The result moves The Daggers above Oxford into 13th, whilst Rochdale drop to 14th on goal difference.
