But they had to work hard to beat already-relegated Rotherham United who showed plenty of spirit, if not a great deal of finishing power, in front of new boss Mark Robins.
Robins, the former Manchester United striker, was quick to identify the need for fire-power after his side slipped to defeat. Despite the slender margin he said: "It was a fair result. We weren't at the races.''
Yeovil fielded a strikeforce much stronger numerically than usual in a bid to get the goals that have eluded them at home and their manager Russell Slade admitted his players should have clinched victory much earlier.
He said: "It was a massive win and I'm obviously delighted. We could have had a few more goals, but we know that three more points will clinch a place in the play-offs.
"We've got to prepare for another important home game against Doncaster next week.''
Yeovil almost snatched the lead in the 24th minute when Marcus Stewart lost his defender to a strike the bottom of a post with a header, but it was second time lucky for the former Premiership man on the stroke of half-time.
Yeovil needed a clincher and almost got it on 51 minutes when loan signing Adam Rooney threaded a superb ball through the defence for Arron Davies. The Welshman lost his angle but fired straight into the side netting.
Chris O'Grady had earlier wasted a couple of chances before the break for the Millers but in fairness they rarely threatened the home goal, as Robins took the opportunity to give the returning Richie Partridge and defender Nat Kerr a run out, with little but pride left to play for in their season.
