A couple of quickfire strikes in the first half from Alexander Isak and Anthony Gordon gave the Magpies a solid lead at the interval. Isak netted his second early in the second period before Fabian Schaer adding the icing on the cake with a fourth of the afternoon late in the day.
It was a fiery start to the match at St James' Park, with both sides getting a few early tackles in. However, it was the hosts that looked sharper in the early knockings and carved out the first chance of the game as Anthony Gordon broke down the right and into the Spurs box, but his cross was just behind Harvey Barnes and Isak and Spurs were able to clear.
Spurs got their first opportunity just a few minutes later when Brandon Johnson beat Dan Burn for pace and picked out Timo Werner in acres of space in the box, but the RB Leipzig loanee was unable to get over the lofted cross and fired his shot high over the crossbar.
Newcastle then began to control the game and came close to the opening goal after two quick corners, the second of which saw Barnes rise the highest but he failed to get enough on his headed attempt and glanced wide.
However, the Magpies' pressure eventually paid off at the half-hour mark when they launched a counterattack through Bruno Guimaraes. The Brazilian found Gordon, who shrugged off Destiny Udogie and put through Isak, who beat Micky van de Ven before slotting the first goal of the afternoon past Guglielmo Vicario in the Spurs goal.
Just 95 seconds later, Eddie Howe's side extended their advantage after Pedro Porro's poor clearance fell to Gordon in the Spurs' penalty area, and the attacker made no mistake with his finish after leaving Van de Ven on the ground with a quick cut inside.
While Spurs were still seeing plenty of the ball, the hosts were the ones that were doing more in possession and could have been three up before the interval had it not been for some good last-ditch defending by Udogie and Van de Ven in the closing moments.
However, the Magpies did not have to wait too long for their third of the afternoon, which came just five minutes after the break, with Isak getting the run on the Spurs backline from inside his own half, and the Newcastle number 14 showed plenty of composure, producing a smart finish to extend his side's lead further and bag his 21st goal of the season.
Ange Postecoglou tried shaking things up at the hour mark, withdrawing Heung-min Son, Yves Bissouma and Rodrigo Bentancur, but the Lilywhites were still struggling to create clear-cut chances while the Magpies looked in total control.
