Lewis Simper’s long-range cracker gave Sutton a come-from-behind 2-1 win at Yeovil.
The Glovers took the lead just after the half-hour mark when Ciaran McGuckin chased a long ball over the top and finished coolly.
But half-time substitute Siju Odelusi equalised when he headed home a deep Simper free-kick six minutes after the break.
Simper then let fly from 25 yards to secure all three points for the visitors, who sit 13th and seven points outside the play-offs with a round to go, giving some optimism for next season.
