Joselu was on target as Newcastle United got themselves up and running in the Premier League this afternoon.
Ciaran Clark and Aleksandar Mitrovic also netted in a convincing 3-0 win over West Ham United at St James's Park.
Joselu was handed his debut after Dwight Gayle failed a late fitness test.
And the striker, signed from Stoke City earlier this month, had a memorable afternoon as Newcastle finally got a win.
The result saw the club, knocked out of the Carabao Cup in midweek, end a difficult week on a high.
There was only one flag in the Gallowgate End at the stadium before the game, and it depicted manager Rafa Benitez, who had questioned whether he could still look at Newcastle as a "long-term" project in the build-up to the fixture.
Newcastle started well. They were better than West Ham with and without the ball.
Joselu won a series of headers and put himself about up front before he got his chance. Mikel Merino played in Christian Atsu, who centred for him on the edge of the six-yard box.
Joselu rolled the ball past Joe Hart to open his account.
Newcastle deserved their half-time lead, and they had Clark to thank for keeping their advantage intact early in the second half.
Rob Elliot saved from Aaron Cresswell, and Clark cleared Javier Hernandez's follow-up effort off the line.
Matt Ritchie forced a save from Hart at the other end of the pitch after good work from Ayoze Perez, and Joselu soon left the pitch to a standing ovation. Aleksandar Mitrovic replaced him.
Newcastle's second goal came in the 73rd minute. A persistent Matt Ritchie won the ball back on the right, and Clark headed in his cross to score his first top-flight goal for the club.
And Mitrovic took the ball around Hart to score a third goal three minutes from time.
