Sutton took the lead with their first attack as a good run from Matthias Curley ended with him finding the net with the aid of the inside of the post.

The game was over nine minutes from the end when substitute Connor Kennedy hammered home from close-range after Aaron Brown headed another Bell corner back into the danger area.
It was 4-1 when Iaciofano crossed from the right and Spencer Weir-Daley finished it off for his first goal since returning to the club.
And Corby rounded off a terrific second half when Aaron Brown headed home the fifth from yet another Bell corner.

During a goalless first half, Poppies goalkeeper Liam Gooch made a fine save to tip an effort onto the post while Kettering’s best chance saw Aaron O’Connor shoot just wide from a Nathan Hicks cross.

The Poppies equalised with seven minutes to go when James Brighton skipped past two players and then laid it off to O’Connor who fired home.
