Another skilful run by Templeton took him past three United defenders before he was closed down in the box by Watson and, though the winger went to ground, referee Iain Brines was unmoved by shouts for a penalty by the travelling fans and Templeton himself made no great appeal for a spot-kick.
Basso came well off his line to deal with Danny Butterfield's hopeful ball into the box but McCombe tried to head it clear, leaving his keeper in no man's land as Watson directed a superb looping header into the unguarded net.
