Northampton earned a narrow win at Plymouth to move level on points with the Pilgrims at the top of League Two.

James Collins gave the Cobblers the lead after he dispossessed Plymouth keeper Luke McCormick from Kelvin Mellor's ill-advised back-pass.

Marc Richards doubled the visitors' advantage after the break when he finished off a swift passing move.

Gregg Wylde turned in Ryan Brunt's cross to give the hosts hope, but they could not find an equaliser late on.
