LEALHOLM made title challengers Boosbeck work hard for their three points, forcing the Cleveland side to come from behind.
Lealholm took the lead on 20 minutes when Crossman cleverly chipped the keeper from the edge of the penalty area.
In an attempt to contain the free-scoring Boosbeck side, Lealholm packed their midfield and played Stuart Marsden, who had an excellent game, as a lone striker.
The game was end-to-end and Boosbeck were not having any luck as they hit the woodwork. Gibson in the Lealholm goal made a number of great saves.
In the second half, Boosbeck came out more determined and showed they are worthy title contenders. Quick passing football allowed Shane Breckon to get beyond the Lealholm defence to score on 60 minutes.
And the game was won with a brilliant goal from Dom Tokorski on 75 minutes with a solo effort, breaking down the left wing and hitting a superb shot that flew over Gibson into the net to give the leaders three valuable points.
