The tempo of the first-half continued in the second, as Kemp was forced into a good save soon after the restart to deny Sussex substitute Brad Santos and keep the score level.
The visitors dominated the majority of the second period but failed to capitalise on their overall possession as the London defence stood firm.
With eight minutes to go Pattenden tried his luck from twenty-five yards out, his dipping strike brought the save of the night from Kemp as he expertly tipped the ball over his crossbar to preserve a point for the hosts.
The draw ended Sussex’s hopes of securing the Championship, but there is plenty of promise for the future…
