Bristol City 0-3 Peterborough
Britt Assombalonga scored twice as Peterborough beat Bristol City.
Tyrone Barnett put Posh ahead, netting from close range after keeper Frank Fielding parried Craig Alcock's shot.
Fielding made up for his mistake when he saved well from Lee Tomlin's penalty, awarded for James O'Connor's trip on Assombalonga.
But the DR Congo-born striker added two to finish the game - an unstoppable 25-yard drill followed by an audacious shot over Fielding.
The result means Bristol City remain without a win in the league this season, while Peterborough have taken 16 points from seven games.

Bristol City head coach Sean O'Driscoll told BBC Radio Bristol:
"Goals change games. When they scored it definitely gave them a lift.
"The first was a goalkeeping error. We thought we were almost on top of the game.
"I was behind him [Assombalonga] for the second goal. If he hits a better shot than that this season then I'll eat my hat.
"They paid £1.2m for him. He's someone I was interested in on loan. We always knew he had that in him."
