Sunderland claimed a sixth successive derby win over 10-man Newcastle United in controversial circumstances this afternoon.
A 45th-minute penalty from Adam Johnson and second-half strikes from Billy Jones and Steven Fletcher gave Sam Allardyce's side a 3-0 win at the Stadium of Light.
Johnson's goal, and events leading up to it, infuriated United head coach Steve McClaren and his players.
The winger struck from the penalty spot after referee Robert Madley dismissed visiting captain Fabricio Coloccini for a foul on Fletcher.
Madley had waved away a penalty appeal from Georginio Wijnaldum seconds earlier after he went down under a challenge from Lee Cattermole.
Up to then, United had dominated the match, but Sunderland took control after the break.
Newcastle started well, and Coloccini forced an early save from Costel Pantilimon after Aleksandar Mitrovic flicked a Jack Colback free-kick into his path.
Mitrovic also headed wide before Cheick Tiote got an early booking for a late challenge on Johnson.
United dominated the half, but the team lacked conviction in the final third of the pitch, and Sunderland's 45th-minute breakthrough came seconds after a penalty claim from Wijnaldum at the other end of the pitch.
Coloccini was penalised for a brainless challenge on Fletcher, who was stretching to reach a ball which goalkeeper Rob Elliot was likely to claim first.
Johnson swept home the resulting penalty to take his derby record to four goals from six games.
McClaren, furious at the decision, remonstrated with the officials.
Tiote made way for defender Jamaal Lascelles at the break, and McClaren was forced into another change early in the second half.
Colback was forced off injured after Lee Cattermole clattered into him. The Sunderland midfielder, however, was not shown a yellow card by Madley, who had earlier warned him about his behaviour.
Anita replaced Colback, who was abused by some home fans as he walked around the perimeter of the pitch.
Mitrovic forced a forced from Pantilimon after the ball was deflected to him, but United's hopes of a comeback were all but ended in the 65th minute, when Jones poked a Yann M'Vila volley into the net.
Johnson hit the crossbar with a shot from outside the area, and Florian Thauvin replaced Dummett in a final United change.
But there was to be no way back for Newcastle.
Fletcher added a third goal four minutes from time.
The result dropped the team to 19th in the Premier League.
