Callum Wilson took his Premier League tally to 15 goals for the season as Newcastle fought back to beat bottom club Southampton at St James’ Park and strengthen their place in the top four.
Saints, who started the day six points adrift of safety, took a surprise lead in the first half when Stuart Armstrong turned in Kamaldeen Sulemana’s low ball following a swift counter.
Newcastle sent on Wilson, who scored twice in the 4-1 win at Everton last Thursday, at half-time and he made an almost immediate impact when he poked in from close range following a free-kick nine minutes after the break.
Wilson then saw a header tipped over before a second was ruled out by the Video Assistant Referee for offside.
But Newcastle completed the turnaround when Theo Walcott deflected a corner into his own net and Wilson finally got his second when he showed great composure to round the goalkeeper and slot in.
Wilson came close to his third in the final few seconds when he hit the bar, but the victory means Newcastle are third, 11 points clear of Tottenham with five games remaining.
Southampton, meanwhile, remain six points adrift at the bottom of the table and staring relegation to the Championship in the face.
