Everton loanee Ellis Simms marked his debut with two goals as Sunderland gained their first three-point haul since returning to the Sky Bet Championship with a 3-2 win at Bristol City.
The striker netted inside four minutes, firing low past Dan Bentley from 20 yards after Ross Stewart had won a tackle on the edge of the box.
City were level in the 10th minute, Andreas Weimann collecting a Zak Vyner pass inside the area and making space to turn and shoot home from a central position.
The hosts went in front six minutes after the break when Chris Martin bundled in a Weimann cross from the right. However, Simms was on target again two minutes later, shooting low through Bentley’s legs from 10 yards, before Stewart headed the winner from Alex Pritchard’s 72nd minute cross to leave the home side with no points to show for their first two matches.
