Dagenham striker Jon Nurse bagged an extra-time double to end Blue Square Bet Premier side Bath City's FA Cup adventure in their 3-1 first-round replay defeat at Twerton Park.
After being held to a 1-1 draw in the first match, League Two Dagenham - who have lost their last seven league games - made the breakthrough through Brian Woodall's header on 20 minutes.
But the Romans drew level via Adam Connolly's stunning strike on 71 minutes before Nurse struck in both halves of extra time to seal a much-needed victory for John Still's men.
Young substitute George Bowerman was the hero as his goal seven minutes into extra-time secured Walsall a 3-2 victory over fellow npower League One strugglers Exeter.
The 20-year-old burst on to a through ball, rounded goalkeeper Artur Krysiak and slotted home for his second senior goal in four days.
The Saddlers were first to threaten when Alex Nicholls cut inside and hammered a 25-yard drive against the crossbar.
The visitors were making little headway, but might have had a penalty in the 39th minute when Richard Logan appeared to be pulled back by Ollie Lancashire.
But Logan a deserved goal three minutes before half-time, cleverly hooking the ball into the roof of the net when Danny Coles headed on a Liam Sercombe free-kick.
Walsall equalised 20 minutes into the second half when Jon Macken hooked in a header from Ollie Lancashire, and Nicholls put the Saddlers in front when he hammered home Bowerman's pass.
However, Grecians sub Elliott Frear forced extra-time as his shot deflected past James Walker before Bowerman had the final say for the Saddlers, who will visit Dagenham in the second round.
