Haringey Borough ended their Essex Premier Division season in second place after a 3-0 win over Takeley.
Boro missed out on top spot by a point as Great Wakering Rovers won at Basildon United on the final day.
Haringey reversed their recent trend and scored all their goals in the second half. The hosts should have been ahead by the interval but their finishing was not up to the standard of some promising approach play.
Takeley rarely threatened but keeper Ashley Harris was called on for one vital contribution midway through the half when he pushed away a close-range header. Darrell Cox scored with a spectacular hook on the turn into the top corner two minutes into the second half and a more relaxed Borough then dictated play for the rest of the match.
Cox completed his second hat-trick in three days with more straightforward finishes in the 61st and 70th minutes. The match was their 15th successive victory and was enough to hold on to second place on goal difference over Enfield (1893).
Boro managed to get the better of Great Wakering Rovers on Tuesday with a 4-0 home win in the Gordon Brasted Trophy second round.
After a goalless first half, Cox maintained his excellent scoring form with a close-range finish.
Dean Fenton headed against the bar but Rakim Richards followed up to net at the far post.
Fenton ensured victory when he raced clear to score and he rounded off the victory with his second of the game two minutes from time.
The win earned Haringey a home tie against Takeley in the quarter-finals tomorrow.
