Harry, a centre forward, fired Leeds ahead with a sixth-minute penalty which was all set to decide the game until the late twist of Boro’s James Wilson levelling in the 94th minute.
England youth international Harry was bagging his fourth league start of the season for the under-18s and the forward’s strike continues his run of netting in every game.
Alfie Cresswell, younger brother of Charlie, captained the young Whites who sit eighth in under-18s Premier League North.
