It was goalless at the break but Harry Phipps, Shay Harrison and Gold Omotayo struck in the second half to put Steve King’s men through.
This was a sixth straight win for the Sports, who are in the middle of a three-tie cup week. They beat Welwyn Garden City in the FA Trophy last Saturday and go to Thame United in the third qualifying round of the FA Cup this coming Saturday.
