Penalty by Ben Chorley hands Orient a slim advantage in match.
The centre-back always backs himself from 12 yards and made no mistake here, sending Cray keeper Whitehouse the wrong way.
Spot kick was won by George Porter on the his debut for Orient at his old club. The 17 year-old was floored inside the box by a ex-team mate.
Orient dominated the play against non-league opponents in the first half.
Now the whole side is to change for the second half.
Trialist Craig Dobson has impressed in centre-midfield as he bids for a contract.
Mike Cestor, the footballer formerly known as Cestor Mike, also caught the eye as well. He was neat and tidy at left back and loved to forage up the field. He beat two challenges to supply a cross into the danger zone, early in the match
