However, the home team made it 3-0 soon after the break for the third, as Richardson ran clear after Rossi's astute touch and rifled a fine shot past SaulDeeney.
The lead should have instilled confidence into the visitors, but instead Torquay hit back minutes later, restoring parity through a sumptuous Hargreaves strike from the edge of the area that nestled into the bottom corner of Saul Deeney's net.
