Former fireman Rhys Griffiths scored on his professional debut as Plymouth Argyle beat Northampton Town for their first League Two win of the season.
Alex Nicholls gave the visitors the lead, firing Ben Tozer's cross home on the turn, before Warren Feeney headed home a leveller.
Griffiths, 32, calmly side-footed home to give them the lead and Curtis Nelson added a third with a looping header.
David Artell headed home deep into injury-time for the Cobblers.
Griffiths, a summer signing from Port Talbot, only played 27 minutes after coming on as a half-time substitute and then coming off with an injury for fellow goalscorer Nelson.
VIEWS FROM THE DRESSING ROOM
Plymouth Argyle manager Carl Fletcher told BBC Radio Devon:
"I'm pleased with Griff, all he wants to do is play and show what he can do and you can see what he can do after 20 minutes.
"We had a good second half which showed a good hunger and desire to do the right things and that got us the win.
"You always want to get the first win of the season, it's like a monkey on your back, you want to get it done and out of the way and move onto the next one.
"You see what an organised and good side Northampton are, and they're going to be there or thereabouts come the end of the season so it's a good win for us today."
Northampton Town manager Aidy Boothroyd told BBC Radio Northampton:
"It was a disappointing result. It is a difficult place to come. We did very well in the first half and got a deserved lead.
"In the second half, we set our stall out to hang on to what we'd got, it was very lacklustre.
"We gave them momentum. We were architects of our own downfall.
"In three months' time, we'll be looking back on these fixtures thinking we've missed out on five points."
