Newcastle had opened the scoring in eight of their previous nine home league fixtures this term, and Eddie Howe’s men looked to extend that record but had two goals disallowed for offside in the first half.
The first was from Anthony Gordon as he tapped Yoane Wissa’s pass into an unguarded net, and the second was Joelinton as he latched onto Fabian Schar’s long ball before finishing well.
Dean Henderson was also by far the busiest goalkeeper in the opening period, as he had to save Schar’s own close-range header, as well as further strikes from Wissa and Lewis Hall.
Still, Palace could have stolen the lead themselves just before half-time, as Jean-Philippe Mateta and Will Hughes struck narrowly wide.
Most Eagles’ eyes were on new signing Brennan Johnson though, and he almost made an immediate impact on debut midway through the second half. The Welshman was played through by Adam Wharton, but could only scuff his effort as Nick Pope saved comfortably.
Newcastle were still threatening though, and Bruno Guimaraes unbelievably almost scored his second direct goal from a corner this season, as the ball clipped the top of the crossbar.
However, the Brazilian was on target with his next effort as he put the Magpies in front, heading home Lewis Miley’s cutback.
The opening goal lifted the hosts to push for a second, and they got it within seven minutes when another dangerous Guimaraes corner delivery troubled Henderson, and Malick Thiaw pounced to poke home his first goal at St. James’ Park.
Joe Willock missed a sitter in stoppage time, but it didn’t matter as the points were secure for Newcastle, who certainly have Palace’s number as they have now kept five successive clean sheets against them at home, with the Eagles now winless in five league matches (D1, L4).
