Perez headed Ki Sung-yueng’s in-swinging free-kick past Ben Foster after the South Korea international had been felled on the edge of the Watford penalty area. Newcastle claimed their first win of the season as Ayoze Perez’s second-half goal handed them victory against a profligate Watford side at St James’ Park.
The visitors – aiming to register their fifth straight Premier League win over the Magpies – went closest to scoring in the first half, with Adrian Mariappa and Gerard Deulofeu both guilty of spurning excellent opportunities to put the Hornets ahead.
Mariappa scuffed a shot wide moments after seeing a close-range header hacked off the line, before Deulofeu dragged a tame effort off target following a delightful through-ball from Abdoulaye Doucoure.
Roberto Pereyra rattled the crossbar in the opening minutes of the second half, but Newcastle – who lost Yoshinori Muto, Jamaal Lascelles and Jonjo Shelvey to injury before the hour mark – rallied to earn their first home points of the season.
The victory lifts Rafa Benitez’s side out of the relegation zone above Cardiff and Fulham.
