A second-half goal from Jon Nurse was the difference as Dagennham & Redbridge saw off relegation rivals Yeovil.
A thrilling first half saw chances created by both sides, but the visitors could consider themselves unlucky not to be ahead at the break.
John Still's men who took the lead against the run of play on 30 minutes when leading scorer Romain Vincelot was completely unmarked to head in Darren Currie's corner.
Just three minutes later the Glovers were level though when Ollie Johnson seized on a slip from Scott Doe to slot past goalkeeper Tony Roberts from just inside the penalty area.
The second half did not see as much goalmouth action, but Johnson should have headed in Luke Ayling's cross, but nodded wide from six yards.
The Daggers took full advantage of the lifeline they were offered and substitute Bas Savage crossed for Nurse in the 72nd minute and the striker turned his marker and shot past goalkeeper Stephen Henderson from close range.
