Clarkson on the double as in-form Motherwell push on
Clarkson and Chris Porter found the net in the opening nine minutes, and although Don Cowie soon reduced the deficit for the Highland visitors, Clarkson made it 3-1 with a sweetly-struck volley just before the interval.
Motherwell took a seventh-minute lead when Ross McCormack sent a crossfield pass to Clarkson on the right side of the box, and he lashed his effort into the roof of the net.
