The Glovers recorded a sixth straight league victory thanks to Paddy Madden's first-half strike - his eighth goal in the last five matches - at fellow play-off hopefuls Coventry.
Yeovil's charge has come just as those above them in the table begin to drop points and that is no accident according to the Town manager.
He said: "The work that they are having to put in at the moment is normal.
"When I say that they look at me as if to say 'that can't be normal', but it's normal for teams that want to win the league and win promotion.
"That desire and commitment, they are the two words because we show good skills at times and every now and then you have to throw yourself in front of something and work back. They have really put everything into it.
"Their work is dragging back the rest of the field. I did say we had to be ready if there were going to be any blips from the teams that are higher up.
"If you believe that a couple of the teams that are up there are going to stay there, then I think you are wrong. Hopefully we can hang on enough to get closer to the top two, but we have to get in those play-off places first."
Madden showed great composure to put Yeovil in front in the final minute of the first half as the Glovers broke at pace when Coventry striker Leon Clarke missed a one-on-one at the other end.
The Sky Blues threw everything at Yeovil in the second half, Stephen Elliott hit the crossbar while Carl Baker had a number of chances.
