Kirton scored for the visitors inside the first minute, and they held the advantage for 20 minutes.
Hammers reserves gradually came back into the game and goals by Barter and Lister gave them the lead at half time. West Ham were so much on top in the second period it was only a question of how many they would score. In fact the only addition was one by Barter. Coventry were lucky to get away so lightly.
