Stevenage gave their promotion hopes a huge boost with victory over fellow contenders Morecambe.
Jon Nurse's first-half goal allowed them to leap-frog their opponents into third place.
From a free-kick, Nurse worked himself into a one-on-one with Steven Drench and then lobbed the advancing keeper.
Morecambe thought they had equalised when Garry Thompson's point-blank effort looked to have crossed the line before goalkeeper Alan Julian cleared.
