Eastleigh boosted their National League play-off hopes and dented Sutton’s automatic promotion chances with a 1-0 win at the Silverlake Stadium.
Sam Smart hit a post for the hosts after six minutes when his shot was deflected onto the woodwork, but Adam Marriott was unable to convert the rebound from close range.
Smart saw another shot parried by Sutton goalkeeper Dean Bouzanis shortly after, while at the other end Donovan Wilson forced a low save from Joe McDonnell.
McDonnell produced a brilliant save to tip Isaac Olaofe’s effort around the post before Marriott grabbed his first Eastleigh goal on 42 minutes.
Tyrone Barnett’s fine ball found Smart, who instantly cut the ball back for Marriott to sweep home.
Bouzanis denied Marriott, who should have done better, from six yards in the second half and the Sutton goalkeeper did well to prevent Jack Payne’s free-kick from going in.
Omar Bugiel fired over from 20 yards for the visitors, who would have gone top with a draw, on goal difference, but stay third.
The Spitfires now take on Notts County for the second time in three games tomorrow night as they look to make it three wins in a row.
