East Grinstead have promotion from County League division two within their grasp following a 1-0 win at Broadbridge Heath.
Manager Bob Smith said: "The next three games are very important. If we can get positive results then it is going to be very hard for the teams below us to make up ground."
Kris Trevor scored the only goal with a 65th-minute penalty after he had been tripped by Heath's Dan Attwater.
Victory came at a cost as defender Dave Garrett was stretchered off with a badly swollen knee and there was more bad news for Smith when Kevin Wright dislocated an elbow playing Sunday football the following day.
