Plymouth Argyle boss John Sheridan praised teenager Tyler Harvey for making the most of his surprise call-up in the 3-0 Sky Bet League 2 Devon derby win over Exeter City.
Plymouth-born Harvey, 19, swept home a 14th-minute free kick from the angle of the box and then finished off Argyle's best passing move of the game to enable Reuben Reid to claim his third goal in two games.
Skipper Curtis Nelson, whose third-minute header came back off the bar, wrapped up the Pilgrims' first win of the season by thrashing the ball home from an 83rd-minute corner.
Speaking about Harvey, Sheridan said: "I thought first half he was tremendous. He got a great goal and had a great little ball for the second goal.
"I am really pleased. I thought our first-half performance was tremendous and ultimately that's what has won us the game. In my eyes really it should have been all over by half-time.
"Everyone knew their job - and did it - and we created a lot opportunities and we had a good work ethic about us.
"Some of the football we played at times was tremendous and to play that sort of football and get that result against your local rivals was pleasing.
"Obviously it's a big game for the supporters, and this one is for them and it's good we have come out of the game with a 3-0 score line.
"Exeter are a good footballing side if you let them play. I think Reuben's goal was great, especially the passage of play leading up to it - and we did that a few times to be fair.
"If we had been a little bit cuter we could have won by more goals but I'm certainly not going to moan with a win, three goals and a clean sheet."
Exeter manager Paul Tisdale refused to press the panic button after the derby loss.
He said: "It is disappointing, but we have got 44 games to go and we are only two games in.
"I will be judging them on how they learn from today's performance. The big picture is that we have got a game at Burton on Tuesday and we have to move on. It is not the time to dwell on it. We have to go into Tuesday's game with renewed optimism, get back on the horse and start again. There are no excuses.
"Plymouth played their game and we didn't play our game. They deserved their goals and their win.
"We know what we are capable of and when it comes to the game I am disappointed that we didn't do what we practice.
"They were more powerful than us, they played their trump card and we didn't play our trump card. I am disappointed we wasted the best pitch in the league.
"We were a lot better in the second half, we competed. There will be players who will learn from this and they will have to learn quickly because the games are coming thick and fast."
